I have search method in my controller:
def search
@search = Sunspot.search [Post, Siri] do
fulltext params[:q]
end
@posts = @search.results
end
Then i have this in my view:
- @posts.each do |p|
%h5= p.title
My question is how to show separately in view if @posts from Post model & if @posts from Siri model.
The reason that i want it seperately is because there is some attr are not exists in Post model but exists in Siri model.
Thanks in advance!
We are using Rake::Task['db:create'].enhance to add a new schema and create an extension in the newly created schema as below.
Rake::Task['db:create'].enhance do
ActiveRecord::Base.connection.execute('CREATE SCHEMA IF NOT EXISTS shared_extensions;')
ActiveRecord::Base.connection.execute('CREATE EXTENSION IF NOT EXISTS "uuid-ossp" SCHEMA shared_extensions;')
end
Can we enhance the test database preparation in the same way?
I have an Event model which has many DateEntry because an event can have multiple datetimes.
I have a view where I see all the events with date entries for a specific day. For which I've made this class method in models/event.rb:
def self.by_date(date)
includes(:date_entries)
.where(date_entries: { begins_at: date.beginning_of_day..date.end_of_day })
end
And it works fine.
Now on the view I loop over the events I grabbed with that query:
@events.each do |event|
# whatever
I am looking for a way to use the date from the selected DateEntry in the loop. I think I have to use ActiveRecords joins method, but I have tried in many ways and when I am not getting an error the output is still the same.
For clarifying, I want to do in the loop something like event.selected_date_entry_by_the_by_date_method.begins_at or something like that.
Lets say I have movies, people and movies_people
class Person < ActiveRecord::Base
has_many :movies_people
has_many :movies, through: :movies_people
class Movies < ActiveRecord::Base
has_many :movies_people
has_many :people, through: :movies_people
class MoviesPerson < ActiveRecord::Base
belongs_to :movie
belongs_to :person
end
The table movies_people has a role attribute, where I want to store the person's job in the movie. Right now I can do things like this in the console:
u = User.first
m = Movie.first
m.people << u
then find the right movies_people entry and set 'role'
retrieving looks like this:
m.people.where(movies_people: {role: :actor})

I am trying to figure out how to execute a "favourite a picture" method in a Rails app, which I am very new to, going from a JS/Meteor background.
The point is I have a User, FavPic, Pic classes:
class User < ActiveRecord::Base
#some user oauth stuff would be here
has_many :fav_pics
has_many :pics_favorited,
class_name: 'Pic',
through: :fav_pics
end
class FavPic < ActiveRecord::Base
belongs_to :user
belongs_to :pic
end
class Pic < ActiveRecord::Base
has_many :fav_pics
has_many :fav_users,
class_name: 'User',
through: :fav_pics
end
and here's my template:
<% if current_user %>
<%= form_tag(root_path, :method => "get") do %>
<p>
<%= text_field_tag :username, params[:username] %>
<%= submit_tag "Search", :name => nil %>
</p>
<% end %>
<ul>
<% @mentions.each do |mention| %>
<li>
<%= mention.text %>
<div class="row">
<% mention.media.each do |media| %>
<div class="col-xs-3">
<%=image_tag(media.media_url, class:"img-responsive")%>
<a href="#" class="fav-img"><i class="fa fa-star fa-2x"></i></a>
</div>
<% end %>
</div>
</li>
<% end %>
</ul>
<% else %>
<p>
Sign in to be able to use the app.
</p>
<% end %>
current_user is a user signed in through Twitter and @mentions is a list of tweets that has the username inputed in the form mentioned. media.media_url is a picture url that is associated with that tweet.
I am trying to get that link (or whatever way it's done in Rails) to add that media URL into the DB so I can list all the images at a separate URL.
my model has a pg array which I use to store integers
Querying using the methods I found from other questions yields errors or gives empty results
MyModel.where("? = ANY (myarray)", 42)
gives
PG::UndefinedFunction: ERROR: operator does not exist: integer = text
and
MyModel.where("myarray @> '{?}'", 42)
gives an empty results, yet I do have a model with 42 as one of the ints in the array
#<MyModel:0x007f9a77dd5608> {
:id => 170,
:myarray => [
[0] 42,
[1] 43,
[2] 58,
[3] 61,
[4] 63
]
Is there a special way to query integers(or floats) within a postgres array in Rails?
the migration
class AddMyarrayToMyModel < ActiveRecord::Migration
def change
add_column :my_models, :myarray, :integer, array: true, default: []
add_index :my_models, :myarray, using: 'gin'
end
end
and schema
t.integer "myarray", default: [], array: true
Currently I'm trying to figure out how to do a calculation the proper and best way using Rails 4.1.
(Simplified example)
id: integer
paid_at: datetime
value: decimal
debit_account_id: references
credit_account_id: references
category_id: references
...
I want a four column list as result, having:
Conditions may be different, an easy case would be:
debit_account_id IN (3, 4)credit_account_id IN (3, 4)
date | earnings | spendings | total |
-----------+----------+-----------+--------+
2015-01-01 | 120.00 | 50.00 | 70.00 |
2015-01-05 | 0.00 | 10.00 | -10.00 |
2015-01-06 | 100.00 | 0.00 | 100.00 |
...
SELECT
DATE(`paid_at`) AS `date`,
SUM(IF(credit_account_id IN(:credit_accounts), value, 0)) AS `earnings`,
SUM(IF(debit_account_id IN(:debit_accounts), value, 0)) AS `spendings`,
SUM(IF(credit_account_id IN(:credit_accounts), value, 0)) - SUM(IF(debit_account_id IN(:debit_accounts), value, 0)) AS `total`
FROM
movements
WHERE
credit_account_id IN (:credit_accounts)
OR
debit_account_id IN (:debit_accounts)
GROUP BY `date`
ORDER BY `date`;
How can I get the expected result in a better way? And how to do it using Rails?

I was looking for quite a long time for a good example on how to de-authorize / disconnect a Stripe Connect account in my Rails app. Perhaps for those that are well versed in making external POST requests, this is trivial, but I'm new and this seemed so hard for someone new to manually crafting POST requests. :)
I'm using the omniauth-stripe-connect gem, which is excellent for connecting an account with Stripe connect. It doesn't appear to have built-in functionality for disconnecting accounts.
Stripe's own documentation says to simply do a POST to their deauthorize URL. But their example is a cURL command, which you can't use natively in Rails. Or rather, it's not advised.
curl http://ift.tt/1b1lNAy \
-u {YOUR_SECRET_KEY}: \
-d client_id=ca_5ry8QONyVRqZAJcezVxwUWlGcJAR7cW1 \
-d stripe_user_id=acct_llriadrqho6HXC
What's the best way to perform that POST in Rails?
Okay, so I created an app with registration system. I successfully deployed the app on Heroku. I can register a user and the confirm links go to their inbox. But when they click the link, it shows "Something went wrong..." on heroku.
the confirm link is like this: http://ift.tt/1bEOsN5
Would really appreciate if someone would give a reply!
My users controller:
def create
@user = User.create(user_params)
if @user.save
UserMailer.registration_confirmation(@user).deliver
flash[:success] = "Please confirm email"
redirect_to root_url
else
flash[:error] = "Something went wrong..."
render 'new'
end
end
def confirm_email
user = User.find_by_confirm_token(params[:id])
if user
user.email_activate
flash[:success] = "Welcome to the Sample App! Your email has been confirmed.
Please sign in to continue."
redirect_to signin_url
else
flash[:error] = "Sorry. User does not exist"
redirect_to root_url
end
private
def user_params
params.require(:user).permit(:name, :username, :email, :password, :password_confirmation, :avatar_url)

self.email = self.email.strip.downcase if self.email
end

if user.email_confirmed
session[:user_id] = user.id
redirect_to root_url, notice: "Logged in!"

default :from => "no-reply@domain.com"

Also added this to my routes file
resources :users do

My app is now going to production and rails-cached-settings after some time expires some configurations I've made. Can anyone help?
I've looked at quite a few other answers on here, but I'm still struggling a bit to figure out how to set up my Rails widget.
I have this code in my widget controller:
def widget
status = Company.friendly.find(params[:id]).widget.active
body = to_json_value(render_to_string('companies/_widget', locals: { profile: self.profile }))
render json: { status: status, html: body }
end
private
def to_json_value(str)
str.gsub!("\"", "\\\"")
str.gsub!(/\n+/, " ")
str
end
The self.profile method just sets up a list of variables that get passed to the partial.
What I want to do is give a user a Javascript script tag that they can embed on their (external) website. When a user hits that page, the script will make an AJAX call to the widget controller and if the widget is turned on, it will receive a string of html to be rendered on the page.
So far I've got the widget controller to return a json object with the status and the html string. What I'm wondering is, how do I set up the js file that the user embeds on their page (ideally without relying on jQuery)?
I should note that the widget will show different information depending on what company (Rails model) it belongs to. I was thinking that this might just be pulled in from params like so:
<script src="http://ift.tt/1GuShkN" type="text/javascript"></script>
I'm also not sure where this widget.js.erb script should live in my rails app. Here is what I have so far for my widget.js.erb:
$.ajax({
type: 'GET',
url: 'http://ift.tt/1IWFXr0 params[:company] %>/widget',
data: {
html: data[key]['html']
},
dataType: 'json',
success: function(data) {
$('#company-widget').html(data.html);
}
});
I have Rails 4 app with two models.
class User
has_many :bids
end
class Bid
belongs_to :user
end
A User can only create one bid per week, so I added the following to the Bid table
add_column :bids, :expiry, :datetime, default: DateTime.current.end_of_week
and the following scopes to the Bid model
scope :default, -> { order('bids.created_at DESC') }
scope :active, -> { default.where('expiry > ?', Date.today ) }
I can now prevent a User creating multiple Bids at the controller level like so:
class BidsController
def new
if current_user.bids.active.any?
flash[:notice] = "You already have an active Bid. You can edit it here."
redirect_to edit_bid_path(current_user.bids.active.last)
else
@bid = Bid.new
respond_with(@bid)
end
end
end
But what is the best approach for validating this at the model level?
I've been trying to set up a custom validation, but am struggling to see the best way to set this up so that the current_user is available to the method. Also, am I adding errors to the correct object?
class Bid
validate :validates_number_of_active_bids
def validates_number_of_active_bids
if Bid.active.where(user_id: current_user).any?
errors.add(:bid, "too much")
end
end
end
I want to show button with image. I have this code
<%= image_submit_tag "down.png", controller: "posts", action: "votedown", post_id: post.id, topic_id: post.topic_id, class: "xta" %>
Its visible properly but not calling action "votedown"
In my routes I have
post '/votedown', to: 'posts#votedown
There is an AcviteRecord Model named User like this:
class User < ActiveRecord::Base
validates :name, :presence => true
validates :email, :presence => true, :uniqueness => true
validates :plain_password, :presence => true, :confirmation => true
validates :plain_password_confirmation, :presence => true
#...other codes
end
It requires that the update of name and email and the update of password are separated.
When only update name and password, using update or update_attributes will cause password validation which is not needed. But using update_attribute will save name and email without validation.
Are there any ways to update particular fields of model with validation without causing the other fields' validation?
I'm a Ruby and Rails newbie and I've been tasked with designing a simple messenger application that takes incoming messages, parses the message for keywords, and translates the messages based on the internal structure to the recipient . I've found resources like Twillo ( This is exactly what I'm looking for http://ift.tt/1xmvv5n) but was wondering if there was a gem or other suggestions you could make that would help me make this small dream a reality. Thanks a bunch!
I'm excited about turbolinks3(it allows you to render only a partial and not reload all the body) You can read more about it from here: http://ift.tt/1HDKIqP It's amazing but I've a problem: In browsers that doesn't support pushState(example ie8/9), I don't know how manage the behavior. It give me this error on IE8:
Could not set the innerHTML property. Invalid target element for this operation.
My Controller code is:
def create
@post = Post.find(params[:post_id])
if @post.comments.create(comment_params)
render '_comment', change: [:comments, :super_test], layout: false, :locals => { comment: @post.comments.last }
else
render json:'error'
end
end
A 'solution' could be that I do:
redirect_to @post, change: [:comments, :super_test]
But then the problem is that it reply with a lot of data that I don't need!(and the response time is bigger) So I reallt want find another solution.
How I can resolve this problem ? I've thought about 2 solution: 1) Use history.js / modernizr for polyfill the pushState on old browsers
But I've tried but I always get the same error(like if I don't have modernizr)

2) Find a way for check if the request is done by turbolinks/pjax or not...and use conditional render or redirect_to
Any suggestions ? I really appreciate it!
PS: Please don't suggest me backbone/angular/ember/react, I already know them(backbone), but I want try turbolinks.
I have several models that are relevant to this question..
Essentially, A User can be assigned a permission through either their UserGroup or directly. UserGroups are tied to specific permissions via the UserGroupPermission model. Users are tied to specific permissions via the UserPermission model.
The end result is to be able to call User.permissions and return every permission assigned to that user either directly or through a UserGroup.
Here is my current model
class User < ActiveRecord::Base
belongs_to :user_group
#Permissions
has_many :user_permissions
has_many :user_group_permissions, :through => :user_group
has_many :permissions, :through => :user_group_permissions #and :user_permissions
end
I've search high and low for a solution to this, but can't seem to find my exact case. Thanks in advance!
Edit: I've been told that is unclear what I'm asking. Hopefully this will help: Basically the User has_many :permissions, :through => :user_group_permissions and :user_permissions, but you can't use an and to join the results together. I'm trying to retrieve and combine the results of both of those relations into one.

secret_key: ENV['STRIPE_SECRET_KEY']
}
# Set our app-stored secret key with Stripe
Stripe.api_key = Rails.configuration.stripe[:secret_key]
Any help will be appreciated!
Update: Thanks for help from stacksonstacks, all I need is asserting 'subscription.user = current_user' under 'current_user.subid = stripe_sub.id', and then call subscription id with "subscription = current_user.subscription" in downgrade method. Now subscription cancelling works!
I have been working on this rails 4 project since yesterday at 3pm and i have not slept. i am all out of ideas as to why this is bombing out. the error message i get is : ActionController::ParameterMissing at /accounts/deposit param is missing or the value is empty: affiliates_account
my accounts_controller looks like this:
class AccountsController < ApplicationController
#before_action :set_account, only: [:show, :edit, :deposit, :credit,
:update, :destroy]
before_filter :set_account, only: [:show, :edit, :credit, :update, :destroy]
before_filter :authenticate_user!
respond_to :html
def index
# @accounts = Account.all
#@accounts = Account.where(id:current_user.id)
if current_user.admin?
@accounts = Account.all
else
@accounts = Account.where(email:current_user.email)
end
respond_with(@accounts)
end
def show
if current_user.admin?
@accounts = Account.all
else
@accounts = Account.where(email:current_user.email)
end
respond_with(@account)
end
def new
@account = Account.new
respond_with(@account)
end
def edit
@accounts = Account.all
end
def create
# @account = Account.new(account_params)
#@account.save
# respond_with(@account)
end
def update
@account.update(account_params)
respond_with(@account)
end
def destroy
@account.destroy
respond_with(@account)
end
def withdrawl
@account = Account.new(account_params)
@account.email = current_user.email
@account.user_id = current_user.id
end
def deposit
@account = Account.new(account_params)
@account.email = current_user.email
@account.user_id = current_user.id
respond_to do |format|
@account.save
end
redirect_to :root
end
private
def set_account
#@accounts = Account.where(id:current_user.id)
@account = Account.find(params[:id])
end
def account_params
# params[:account]
params.require(:account).permit(:created_at, :email, :credit, :debit,
:acctbal, :depotype)
end
end
and my Model for accounts.rb
class Account < ActiveRecord::Base
belongs_to :user
validates :depotype, presence: true
DEPOSIT_TYPES = [ "Check", "Credit card", "Purchase order" ]
validates :depotype, inclusion: DEPOSIT_TYPES
def final_acct_bal
accounts.to_a.sum {|account| account.final_acct_price}
end
end
and i created a new deposit.html.erb because the new.html.erb kept giving me a weird error and someone mention that the create method is tied to that and that i should create a seperate form page. so i did and now im having a tough time linking my deposit action method to that page so that my "add funds" button on my index.html.erb will go to it. and perform the requested actions accordingly.
<h1>Editing account</h1>
<%= render 'form' %>
<%= link_to 'Show', @account %> |
<%= link_to 'Back', accounts_path %>
my index.html.erb with that link_to button
<div class="container">
<h1>Listing Accounts Inquiries</h1>
<h2>Your Account information</h2>
<table border="3">
<table class="table table-striped">
<thead>

</td>
</tr>
<% end %>
<tbody>

<%= link_to "Add Funds", deposit_accounts_path, method: :post, :class =>

<% if can? :manage, Users%>

<% @accounts.each do |account| %>

<% end %>

</div>
<% end %>
i think this part of the params is hosing it up, params.require(:account) but i dont know what to do to change this so that it works and nothing else breaks
Everywhere I looked there were 2 examples
either
Book.where("'history' = ANY (subjects)")
to query a book with a specific subject in the subject array
or
Book.where("subjects @> ?", '{'history', 'drama'}')
to query books that the subjects array has both history and drama
How do I query for books that has either history or drama or both?
In order to test emails in my rails app, I tried adding the mailcatcher gem. When I first ran mailcatcher, I got an error with eventmachine that effectively broke the mailcatcher server. I realized this was due to the version of mailcatcher being used, but after I tried to update to a newer version, I am having dependency issues. I got the following error when I ran bundle:
Bundler could not find compatible versions for gem "thin":
In Gemfile:
mailcatcher (>= 0.6.1) ruby depends on
thin (~> 1.5.0) ruby
thin (1.6.3)
Is there any possible workaround, or other suggestions? I don't want to lock thin at 1.5.0. Older versions of mailcatcher are broken, and the updated versions aren't playing nicely with thin. I may just find another gem to test emails...
I am a little confused as to where "jobs" and "workers" fall in the workflow of background processing. I'm trying to write my first rake tasks that send periodic emails and almost all tutorials are pre-rails 4.2, and so they suggest I create a Sidekiq worker, etc....though now, that Active Job is rolled into Rails 4.2...I think I can just create a Job...am I correct? I am using Redis, Sidekiq, Rails 4.2 and PG. I am using the Whenever gem for scheduling
Here is what I am doing to create these recurring emails:
send_test_job.rb
class SendTestJob < ActiveJob::Base
queue_as :default
rescue_from(StandardError) do |exception|
notify_failed_job_to_manager(exception)
end
# perform(users, project_archives, rakelogs, projects, user_archives)
def perform
@users = User.all
@subject ="Test Email"
if @users.present?
AdminNotifierMailer.hourly_roundup(@users, @projects, @subject).deliver_later
else
end
end
private
def notify_failed_job_to_manager(exception)
AdminNotifierMailer.job_failed(User.find(?), exception).deliver_later
end
end
scheduler.rake
namespace :admin do
desc "sends a test email"
task :send_test => :environment do
puts "sending Test Job"
SendTestJob.perform_later
puts "done"
end
end
config/schedule.rb (for whenever gem)
every 1.minutes do
rake "admin:send_test", :output => {:error => 'error.log', :standard => 'cron.log'}
end
sidekiq.yml (the code hinting color on this is screwy...so this may be an issue)
---
:concurrency: 25
:pidfile: ./tmp/pids/sidekiq.pid
:logfile: ./log/sidekiq.log

- [high_priority, 2]
As you can see I have no workers...but that's because I can't really figure out where to put one or if I need one.
I am implementing website on ruby on rails and i need a gem to help me to track spammers on the website or can i use ahoy gem to help me ? p.s the website for selling products .
I have a problem with using angularjs-google-maps in production enviorment. In development everything is ok, but I can't compile assets on production server.
I noticed that there are a lot of unnecessary files included with ngmap gem.
RAILS_ENV=production rake --trace assets:precompile
** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)

It appears that in some controllers there are comments mentioning which route it uses, however it's not specified in the route file. For instance:
# GET /users
def index
@users = User.all
end
# GET /users/1
def show
@tweet = current_user.tweets.build if signed_in?
@feed_items = @user.tweets.paginate(page: params[:page])
end
(in users_controller.rb)
My question is, how does rails app know that there is an endpoint here? I would like to know whether I can actually collect all the routes in one file?
So I am trying to build a wicked wizard. I have User and Boat Model. When Boat model is created, all the steps starts. The first #show action works fine for the first step. But I have a problem with the `second step.
Here is my
#routes
resources :users
resources :boats, except: :destroy do
resources :pictures
end
resources :boat_steps
#boat_steps controller
class BoatStepsController < ApplicationController
include Wicked::Wizard
before_action :logged_in_user
steps :model, :pricing, :description, :picture
def show
@boat = current_user.boats.last
render_wizard
end
def update
@boat = current_user.boats.last
@boat.update_attributes(params[:boat])
render_wizard @boat
end
end
#model.html.erb
<% provide(:title, "List Boat") %>
<h1>List your Boat</h1>
<div class="row">
<div class="col-md-6 col-md-offset-3">
<p>AHoy! <%= current_user.name %>. It only takes 5 mins to fill the form!.</p>
</br></br>
</br>
<%= form_for(@boat, url: wizard_path, method: put) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<h2>Brand & Model</h2>
<%= f.label :brand %>
<%= f.text_field :brand, placeholder: "Brand Name", class: 'form-control' %>
<%= f.label :model %>
<%= f.text_field :model, placeholder: "Model", class: 'form-control' %>
<%= f.label :boat_category, "Boat Category" %>
<% if @boat.boat_type == "Power" %>
<%= f.collection_select(:boat_category, Power.all, :name, :name, {:prompt => "Select a Category"}) %>
<% else %>
<%= f.collection_select(:boat_category, Sail.all, :name, :name, {:prompt => "Select a Category"}) %>
<% end %>
<% if @boat.boat_type == "Sail" %>
<%= f.label :mast_material, "Mast Material" %>
<%= f.collection_select(:mast_material, Mast.all, :name, :name, {:prompt => "Select a Material"}) %>
<% end %>
<%= f.label :hull_material, "Hull Material" %>
<%= f.collection_select(:hull_material, Hull.all, :name, :name, {:prompt => "Select a Material"}) %>
<%= f.label :boat_length, "Boat Length" %>
<%= f.number_field :boat_length, placeholder: "Ex. 15", max: '50', class: 'form-control' %>
<%= f.submit "Next", class: "btn btn-primary" %>
<% end %>
</div>
</div>
And here is the
#pricing.html.erb
<h2>Pricing</h2>
<%= form_for (@boat, url: wizard_path) do |f| %>
<%= f.radio_button(:captained, "Captained") %>
<%= f.label(:captained_captained, "Captained") %>
<%= f.radio_button(:captained, "Bareboat") %>
<%= f.label(:captained_bareboat, "Bareboat") %>
<%= f.label :daily_price, "Daily Price (TL)" %>
<%= f.number_field :daily_price, placeholder: "Ex. 180.00", max: '1000.00', class: 'form-control' %>
<%= f.submit "Next", class: "btn btn-primary" %>
<% end %>
Lastly,
#boats controller
def new
@boat = Boat.new
end
def create
@boat = current_user.boats.new(boat_params) if logged_in?
if @boat.save
#flash[:success] = "Continue from here"
redirect_to boat_steps_path
else
render 'new'
end
end
def show
@boat = Boat.find(params[:id])
end
def edit
@boat = Boat.find(params[:id])
end
def update
@boat = Boat.find(params[:id])
if @boat.update_attributes(boat_params)
flash[:success] = "The Boat Saved"
redirect_to root_path
else
render 'edit'
end
end
So, the first form, (model.html.erb) opens as; http://localhost:3000/boat_steps/model, when I click next, the url becomes;
http://localhost:3000/boat_steps/id=157
It is because of the #show action (@boat = current_user.boats.last) I believe but I could not find a way to do it. If I make it @boat = current_user.boats then I receive undefined method to_key'
Here is the log when I use ; @boat = current_user.boats.last

I have a website that translates DNA codons to MRNA codons. I created am immutable immutable 64 row DB model with 3 columns with sqlite, which I then preceeded to seed. Basically, what I want is the user to input a string into a text-area and break the string into 3 character string fragments "ttcttaatt..." --> (dnaCodon) [ttc][tta][att] --> that match to the database returning matched results (mrnaCodon ) [uuc] [uua] [auu]. I created a search form on one of my static pages
I am running into trouble now with my routes in the search form. I want to query the search and then return it either to the same page, or a different page- whichever method is easier and makes more sense. I initially created my DB without scaffolding because I don't want it accessible by users for alterations. I ended up creating a scaffolding folder so I dunno why it's not connecting to the database. My page refreshes but does not return the DB query
app/controllers/aa_data_bases_controller.rb
class AaDataBases < ApplicationController
def index
if params[:search]
@aa_data_bases = AaDataBases.search(params[:search]).order("created_at DESC")
else
@aa_data_bases = AaDataBases.all.order('created_at DESC')
end
end
end
views/static_pages/sequence.html.erb It's in this static page that the problem route is, in form_tag("/sequence"... When I run rails server the pages loads, i can input but page refreshes and nothing happens

I'm trying to blank out a bunch of columns in an easy-to-read formatted code. I know I could just do this:
@user = User.find(3)
@user.column1 = nil
@user.column2 = nil
@user.column3 = nil
etc...
But that doesn't seem like a very Ruby way to do things, nor is it particularly clean to read.
I'm trying to figure out why I can't just do an 'each do' array like this:
columns = [ "key", "provider", "uid", "access_code",
"customer_id", "cc_id", "cc_brand", "cc_last4",
"cc_expiration", "last_payment_id", "last_payment_date",
"last_payment_amount" ]
columns.each do |record|
@user.record = nil
end
@user.save
I receive the following error:
undefined method `record=' for #<User:0x00000003a91d18>
I know that similar questions have been asked before, but they are usually related to updated a bunch of different tables. I'm only interested in the user table.
Also, there are a lot of answers linking to http://ift.tt/1apioMa. But that's an old deprecated method that apparently bypasses callbacks. That seems rather dangerous.
Can anyone think why a simple 'each do' array won't work?
I'm fairly new at integrating APIs in Ruby on Rails but I want to use Soundcloud's API to embed a player widget when provided a Soundcloud URL from a user. Right now I have the widgets embedded in my table through a test link. Each post contains string called link but I don't know how to reference it inside the controller. Or would I point to link in my view? Here's what I have so far. Any help would be appreciated.
class PostsController < ApplicationController
require 'soundcloud'
def index
@client = Soundcloud.new(:client_id => 'xxxxx')
@posts = Post.search(params[:search]).order(sort_column + " " + sort_direction)
track = @client.get('/resolve', :url => post.link )
@trackid = track.id
end
private
def set_post
@post = Post.find(params[:id])
end
def post_params
params.require(:post).permit(:link)
end
end
Here's the corresponding view.
<% provide(:title, 'Home') %>
<table>
<thead>
<tr>
<th>Link</th>
</tr>
</thead>
<tbody>
<% @posts.each do |post| %>
<td><div id="player"><object height="70" width="100%"><param name="movie" value="http://ift.tt/1ECyM9F @trackid %>&player_type=tiny{widgetParams}"></param>

I'm writing trading bot on ruby and I need to constantly do some calculations based on Exchange's orderbook depth data across several daemons (daemons gem).
The problem is that right now I'm fetching data via Exchange's API separately in each daemon, so I ran into API calls limit (40 requests/second). That's why I'm trying to utilize ruby Drb to share orderbook data across several processes (daemons) in order to not sending unnecessary API calls.
Although I m not sure how to constantly consume API on the server side and provide the latest actual data to the client process. In the sample code below, client will get data actual at the moment when I started server
server_daemon.rb
require 'drb'
exchange = exchange.new api_key: ENV['APIKEY'], secret_key: ENV['SECRET']
shared_orderbook = exchange.orderbook limit: 50
DRb.start_service('druby://127.0.0.1:61676', shared_orderbook)
puts 'Listening for connection… '
DRb.thread.join
client_daemon.rb
require 'drb'
DRb.start_service
puts shared_data = DRbObject.new_with_uri('druby://127.0.0.1:61676')
Say I have this query:
red_houses = user.houses.where(color: 'red')
How can I pop the last element of red_houses?
I know I can do this red_houses[1..-2], but not red_houses.pop, is there any way I am missing?
Basically I want to delete the last element and get the remaining relation without the last element on it.
I have installed Ahoy to give some user analytics on my rails application. I am running rails 4.1.10 and using Postgres 9.3.10
I have added the gem to my gemfile:
gem 'ahoy_matey'
And I have run :
rails generate ahoy:stores:active_record -d postgresql
rake db:migrate
As per the docs.
I also added //=require ahoy after jquery in the application.js assets file.
I was not sure if visits and events would be tracked automatically - so I went to a couple of pages and checked manually in the DB and I see no entries in the visits or ahoy_events tables. So I manually coded this into my landing page index controller action:
ahoy.track "Viewed Landing", title: "Landing page viewed"
And this line causes the following error:
NameError in LandingPageController#index
undefined local variable or method `ahoy' for #<LandingPageController:0x007fa634fee7f0>
(Listed in full here : http://ift.tt/1Fm5sTH)
Can anybody help me get ahoy logging visits and events please! Ideally I want it to track everything, automatically if there is some golden switch I need to press :)
I'm trying to simplify and DRY up my rails code so as not to duplicate lists of URLs in multiple places and have to keep them in sync. I have a controller with a method parent that has instance variables for lists of urls in different categories, i.e.
def parent
@collection1 = [
["Link 1", "http://link1.com"],
["Link 2, "http://link2.com"]
]
@collection2 = [
["Link 3", "http://link3.com"],
["Link 4, "http://link4.com"]
]
end
Then in my views I have a file parent.html.erb with code
<% @collection1.each do |link| %>
<a href="<%= link[1] %>" target = "_blank" class="btn btn-primary btn-block" role="button"><%= link[0] %></a>
<% @collection2.each do |link| %>
<a href="<%= link[1] %>" target = "_blank" class="btn btn-primary btn-block" role="button"><%= link[0] %></a>
But I have another view, child.html.erb that I want to just display collection 1, so
<% @collection1.each do |link| %>
<a href="<%= link[1] %>" target = "_blank" class="btn btn-primary btn-block" role="button"><%= link[0] %></a>
But in order to do this I have to define another method in the same controller:
def child
@collection1 = [
["Link 1", "http://link1.com"],
["Link 2, "http://link2.com"]
]
which is the same collection as I have in the parent method. That works but then if I want to change one the links I have to change it in both places. Please advise, I am pretty new to rails but realize this can't possibly be the way you're supposed to this! Thank you.
I need to perform a batch action on all of the records after filtering in activeadmin. I've read following question: ActiveAdmin: batch select all pages but in this case select is fairly simple. We can use just Model.all or something similar. But is it possible to select all of the records on all of the pages after the filter was applied?
I was wondering if it were at all possible to change the element type of the wrapper for newly inserted inputs. Going through the docs I was unable to find a way in doing so.
Simply put I need to change nested-fields div into a table and change the inserted inputs, that have a class of input into trs with the inputs wrapped inside tds. This would look something like this:
<table class="track-form nested-fields">
<tr><td><%= f.input :disc %></td></tr>
<tr><td><%= f.input :number %></td></tr>
<tr><td><%= f.input :name %></td></tr>
</table>
Unfortunately manually changing these tags is only ignored when the views are rendered. Here's what the view code currently looks like without the table elements added:
Form View
<%= simple_form_for(@album) do |f| %>
<div class="form-inputs">
...
</div>
<div class="form-inputs">
<%= f.simple_fields_for :tracks, tag: "table" do |track| %>
<%= render 'track_fields', :f => track %>
<% end %>
<div id='links'>
<%= link_to_add_association 'Add a Track', f, :tracks %>
</div>
</div>
Partial
<div class="track-form nested-fields">
<%= f.input :disc %>
<%= f.input :number %>
<%= f.input :name %>
<%= link_to_remove_association "remove track", f %>
</div>
Write a method that takes in a string of lowercase letters (no uppercase letters, no repeats). Consider the substrings of the string: consecutive sequences of letters contained inside the string. Find the longest such string of letters that is a palindrome.
Based on local method Palindrome?(string), I implemented longest-palindrome(string) as below with test cases:
def palindrome?(string)
i = 0
while i < string.length
if string[i] != string[(string.length - 1) - i]
return false
end
i += 1
end
return true
end
def longest_palindrome(string)
dix = 0
lstr = ""
lstrc = nil
while dix < string.length
dix2 = 1
while dix2 < string.length
str = string.slice(dix,dix2)
count = str.length
if palindrome?(str)
if lstrc == nil || lstrc < count
lstr = str
lstrc = count
end
end
dix2 += 1
end
dix += 1
end
puts(lstr)
return lstr
end
# These are tests to check that your code is working. After writing
# your solution, they should all print true.
puts(
'longest_palindrome("abcbd") == "bcb": ' +
(longest_palindrome('abcbd') == 'bcb').to_s
)
puts(
'longest_palindrome("abba") == "abba": ' +
(longest_palindrome('abba') == 'abba').to_s
)
puts(
'longest_palindrome("abcbdeffe") == "effe": ' +
(longest_palindrome('abcbdeffe') == 'effe').to_s
)
Test results as below:
bcb
longest_palindrome("abcbd") == "bcb": true
bb
longest_palindrome("abba") == "abba": false
effe
longest_palindrome("abcbdeffe") == "effe": true
Why did the second test failed?
I have a Spring websocket application that I want to access from another client.
I am using sockjs to do this.
When connection to http://localhost:8080/hello/info is attempted to open, I get a 403 (forbidden) error.
Here is my CORS conf in Spring:
@Component
public class SimpleCORSFilter implements Filter {
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "http://localhost:3000");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE, HEAD, PATCH");
response.setHeader("Access-Control-Allow-Headers",
"Origin, Content-Type, Accept, Cookie, Connection, Accept-Encoding, Accept-Language, Content-Length, Host, Referer, User-Agent");
chain.doFilter(req, res);
}
public void init(FilterConfig filterConfig) {}
public void destroy() {}
}
If I try to use the socket from the page that Spring it self server, it works without problems. But when I do it from another client that uses that same Angular code that I have in Spring, it fails with the error above.
Here is the comparison of Request headers:

Is the problem with the cookie header?
I did this the problematic client but nothing changed. But it should not matter also as both my Spring application and the Ruby on Rails application have exactly the same Angular code that is used to connect to the websocket.
app.config([
'$httpProvider', function($httpProvider) {
$httpProvider.defaults.withCredentials = true;
}
]);
This is a strange one. I've had a working MailChimp, Gibbon, RoR app going for a couple of years now, and I went to go use part of my app this week and realized that the integration was no longer working. I am not receiving any errors, and some basic testing shows that the exception section of the code is never called.
Here is the code I am using:
begin
gb = Gibbon::API.new(mailchimp_api_key)
gb.lists.subscribe( id: mailchimp_list_id, email: {email: email} )
rescue Gibbon::MailChimpError => e
logger.error "Mailchimp threw an error. The code is: #{e.code}, with message: #{e.message}"
end
Some code edited for readability, but assume that the variables are defined and no errors are thrown.
What I'm looking for is some debugging help. I can't seem to find a way to debug the integration to know if there is something silently failing or not. Does anyone have any tips for debugging this outside of trying to catch a raised exception?
I'm using log4jRuby to log the errors in my Rails application. Normally in development, any exceptions raised in the application will be directly displayed on the page. In production I set config.consider_all_requests_local = true in my enviorments/production.rb file. So that the users wont see any ugly exceptions. The page only shows a 500 server error when an exception occurs in production. I except the logs for the exception to be shown in my log files, but it doesn't. Now it's becoming difficult to know the reason why an exception occurred on production. Is there any other configuration that I'd have to set to achieve the same?

I have a user model and boat model. They are associated. The thing is, when user creates a boat, the #create action redirects user to #edit page. In #edit page I have a long form that I want to use for wicked. Every video I watched, they used wicked gem after #create action. So I do not know if I can use it for the edit page. I have tried but encounter with an error.

# map to name and id for use in our options_for_select
@years = brand.years.map{|a| [a.name, a.name]}.insert(0, "Select a Year") #use a.name here instead of a.id
@models = brand.models.map{|s| [s.name, s.name]}.insert(0, "Select a Model")#use s.name here instead of s.id
end
def update_models
# updates model based on year selected
year = Year.find_by_name(params[:year_name])
@models = year.models.map{|s| [s.name, s.name]}.insert(0, "Select a Model") #use s.name here instead of s.id
end
private
def boat_params
params.require(:boat).permit(:brand, :year, :model, :captained, :boat_type, :daily_price, :boat_length, :listing_tagline, :listing_description, :boat_category, :hull_material, :mast_material)
end
end
The edit page works fine. Then when I click next to get the pricing step I get error, it might because of the boat_steps controller' s #show action or the from in the pricing.html.erb. But I could not find a solution. Here is the pricing.html.erb
<h2>Pricing</h2>
<%= form_for @boat, url: wizard_path do |f| %> <!-- HERE PROBLEM-->
<%= f.radio_button(:captained, "Captained") %>
<%= f.label(:captained_captained, "Captained") %>
<%= f.radio_button(:captained, "Bareboat") %>
<%= f.label(:captained_bareboat, "Bareboat") %>
<%= f.label :daily_price, "Daily Price (TL)" %>
<%= f.number_field :daily_price, placeholder: "Ex. 180.00", max: '1000.00', class: 'form-control' %>
<%= f.submit "Next", class: "btn btn-primary" %>
<% end %>
So I get this error;
NoMethodError in BoatStepsController#show
undefined method `to_key' for #<Boat::ActiveRecord_Associations_CollectionProxy:0x007f85a5291fa8>
Or should I use wicked after #create action, instead of #edit action?
I have two models, Room and Student. Room has_many Students. Student belongs_to Room.
I got an error Room can't be blank when I try to add Student to Room during creating a new Room.
My guess is that, upon submission, child object (student) is saved before parent object (room) is saved. Is there a way to bypass the order without remove the NOT NULL setting on room_id? Or my guess is wrong? Or even worse, I am doing it wrong?
# app/models/room.rb
class Room < ActiveRecord::Base
validates :name, presence: true
has_many :students
accepts_nested_attributes_for :students
end
# app/models/student.rb
class Student < ActiveRecord::Base
validates :name, presence: true
belongs_to :room
validates :room, presence: true # room_id is set to NOT NULL in database too.
end
# app/admin/room.rb
form do |f|
f.semantic_errors *f.object.errors.keys
f.inputs "Room Details" do
f.input :name
f.has_many :students do |student|
student.input :name
end
end
f.actions
end

I'm currently working on a project using:
I tried to run bundle install but keep getting the following error:

and, following:

I have a data uri which I want to upload to the server and store it as a paperclip image attachment. So I used the info on this link to convert the data uri into a blob and then used FormData to upload it to the server. My coffeescript file looks like this
dataURLtoBlob = (dataURL) ->
binary = atob dataURL.split(',')[1]
array = []
i = 0
while i < binary.length
array.push binary.charCodeAt(i)
i++
return new Blob [new Uint8Array(array)], {type: 'image/png'}
file = dataURLtoBlob(imageSrc)
fd = new FormData()
fd.append "image", file
$.ajax({
url: "/posts",
type: "POST",
data: fd,
processData: false,
contentType: false,
});
And this is the create action in my controller
image = params[:image]
name = SecureRandom.hex + "png"
File.open("#{Rails.root}/public/uploads/#{name}", 'wb') do |f|
f.write(image.read)
end
This works perfectly for storing the image on the server. But how do I integrate it with paperclip, i.e. to generate thumbnails, urls for these images? Thanks in advance.
When I create an object via FactoryGirl and Faker, shell show me an error
[1] pry(main)> FactoryGirl.create(:company)
[DEPRECATION] requiring "RMagick" is deprecated. Use "rmagick" instead
but when I create object in development db - it's ok
there is factory
factory :company do
title Faker::Company.name
image Faker::Avatar.image("my-own-slug", "200x200")
end
how fix?
I am following the RailsCast tutorial for Exporting CSV and Excel. My goal is to export to excel. Everything is working fine except that I would like each Product to have its on sheet. Below is the code per the tutorial and then my attempts at adjusting for my needs.
/config/application.rb
require File.expand_path('../boot', __FILE__)
require 'csv'
require 'rails/all'
/config/initializers/mime_types.rb
Mime::Type.register "application/xls", :xls
/app/models/product.rb
class Product < ActiveRecord::Base
attr_accessible :name, :price, :released_on
def self.to_csv(options = {})
CSV.generate(options) do |csv|
csv << column_names
all.each do |product|
csv << product.attributes.values_at(*column_names)
end
end
end
end
app/controllers/products.rb
class ProductsController < ApplicationController
def index
@products = Product.order(:name)
respond_to do |format|
format.html
format.csv { send_data @products.to_csv }
format.xls
end
end
end
/app/views/products/index.xls.erb
<?xml version="1.0"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"

xmlns:html="http://ift.tt/qQdaDR">
<Worksheet ss:Name="Sheet1">

<Row>
<Cell><Data ss:Type="String">ID</Data></Cell>
<Cell><Data ss:Type="String">Name</Data></Cell>
<Cell><Data ss:Type="String">Release Date</Data></Cell>
<Cell><Data ss:Type="String">Price</Data></Cell>
</Row>
<% @products.each do |product| %>
<Row>
<Cell><Data ss:Type="Number"><%= product.id %></Data></Cell>

<Cell><Data ss:Type="Number"><%= product.price %></Data></Cell>
</Row>
<% end %>
</Table>
</Worksheet>
</Workbook>
All of that works to create an excel sheet with a column of Products and other columns for the attributes. As an attempt to create individual worksheets for each Product, I iterated through Products above the element in my .xls.erb. This led to the excel file being unreadable though.
/app/views/products/index.xls.erb

<Cell><Data ss:Type="Number"><%= product.price %></Data></Cell>
</Row>
</Table>
</Worksheet>
<% end %>
</Workbook>
How can I change my .xls.erb file to create a new sheet for each Product row?
I've read the docs on how to customize wrapper's globally in SimpleForm but what I'd like to do is change the wrapper specially for one view and the partial inside of it. Right now the partial is wrapped in a div with the class name nested-fields.
With the use of cocoon I'm also dynamically inserting new inputs that are also wrapped in divs.
Simply put I need to change nested-fields div into a table and change the inserted inputs, that have a class of input into trs with the inputs wrapped inside tds. This would look something like this:
<table class="track-form nested-fields">
<tr><td><%= f.input :disc %></td></tr>
<tr><td><%= f.input :number %></td></tr>
<tr><td><%= f.input :name %></td></tr>
</table>
Unfortunately manually changing these tags is only ignored when the views are rendered. Here's what the view code currently looks like without the table elements added:
Form View
<%= simple_form_for(@album) do |f| %>
<div class="form-inputs">
...
</div>
<div class="form-inputs">
<%= f.simple_fields_for :tracks, tag: "table" do |track| %>
<%= render 'track_fields', :f => track %>
<% end %>
<div id='links'>
<%= link_to_add_association 'Add a Track', f, :tracks %>
</div>
</div>
Partial
<div class="track-form nested-fields">
<%= f.input :disc %>
<%= f.input :number %>
<%= f.input :name %>
<%= link_to_remove_association "remove track", f %>
</div>
I have a custom jquery.validationEngine Ajax call that I can get working by manually creating a file called jquery.validationEngine-en.js, copying in the plugins code and adding my custom rule (see below).
From what I can gather, this results in the file of the same name pulled in via //= require jquery.validationEngine-en being replaced by my custom file.
I'm wondering is this the best way to do this? Is there a way to add custom rules to the //= require jquery.validationEngine-en in application.js file without having to create my own?
I hope I've explained that properly.
