There is a class Commerce and its constructor will initialize an object named commerce. LineItem is a class with in the Commerce class. LineItem class has a method named "ssm". when this method "ssm" is invoked it will initialize an object of another class named SSM. In our problem, we need pass to the "ssm" method as a function argument in another Test class.
def autoUpdate(docNum, type, varName, value)
type = method(Commerce::LineItem:ssm)
commerce.line_item.type.call(varName).set(value)
end
In the place of the function parameter 'type', it should be replaced by different method names from the class LineItem. However the above function autoUpdate throws an error. How to pass child class methods as function parameters in another class.

The ERROR is:
ActionView::Template::Error (undefined method `my_leaders_path' for #<#<Class:0x007fadc5f8cdf0>:0x007fadc3d929e8>):
Why this happened: undefined method `my_leaders_path'? should that be fieldwork_my_leaders_path?
This date field:
<%= f.text_field :my_date, id: 'id-123', type: 'date' %>
doesn't get bound to the value of my_date of the model on the, for example, edit page. When I load the page, it's always "empty".
Why is that? I also tried:
<%= f.text_field :my_date, id: 'id-123', type: 'date', value: '11/11/11' %>
<%= f.text_field :my_date, id: 'id-123', type: 'date', value: '11-11-11' %>
and it also didn't work.
I have a production application with Workless and DJ & MongoMapper running just fine - after a document is created in the delayed_jobs queue Workless starts a Heroku worker and works off the job - shuts it down when there are no more jobs - this is brilliant.
I'm migrating over to MongoId and I've found that Workless will not start up.
At first I thought it had to do with the failed_at field not being present on newly created documents in this collection which I created an issue for here: http://ift.tt/1ASsr50
But patching my own version of DJ to forcefully set this attribute to nil hasn't resolved the issue of the after_create callback not firing.
Has anyone ran into any issue with Workless gem where it won't start a worker on Heroku and your solution was NOT one of the following:
?
I cannot figure the cause of after_create not firing when it should. I also couldn't successfully run the spec tests locally with workless, need more study of this gem to get that going.

I have Ruby on Rails application on heroku.
We are using ruby 2.1.5
ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux]
And Ruby on Rails 4.1.1
Gemfile: http://ift.tt/1awG1mb
Sprockets version (extract from gemfile.lock):
sprockets (2.11.0)
hike (~> 1.2)
multi_json (~> 1.0)
rack (~> 1.0)
tilt (~> 1.1, != 1.3.0)
sprockets-rails (2.2.4)
actionpack (>= 3.0)
activesupport (>= 3.0)
sprockets (>= 2.8, < 4.0)
Of course we are using digested assets
e.g. application-d99ed24f47c5c39b96889148558cb16c.js - THEY are working
Besides that, I am using non-digested assets for CKEditor,
I put them under RAILS_ROOT/public/assets directory
so /assets/ckeditor/config.js should point to RAILS_ROOT/public/assets/ckeditor/config.js
Issue
I can't update assets under public/assets
I updated one file from CKEditor, but it doesn't show the changes either when I:
I commited the changes, build on CircleCI passes (continuous integration service). Auto-deploy updates the staging server.
But I still get the old file.
MOREOVER I looked at source of the file using heroku run bash
heroku run bash
cd public/assets/ckeditor
cat config.js
and it RETURNS the old version. Changing this via various tricks e.g. rm cp echo NEW_CONTENT >> NEW_FILE.js also doesn't work.
Heroku returns old version...
PS Moving CKEditor from public/assets/ckeditor to app/assets/ckeditor didn't solve the issue.
I need to create a form that involves three hierarchies. For example, the form allows the user to create and edit the "company_apps" which belong to a particular company. Each of these "company_apps" can have one or more "app patterns". Creating a form for company_apps nested within a company seems simple enough but I'm confused on how to organize the form so that the user can create one or more app patterns for each particular company_app. Posted is a bullet points list of how I'm trying to arrange the form.
comany.rb
class Company < ActiveRecord::Base
has_many :company_apps, :foreign_key => 'ca_company_id'
accepts_nested_attributes_for :company_apps
end
company_app.rb
class CompanyApp < ActiveRecord::Base
self.table_name = 'company_apps'
has_many :app_patterns, :foreign_key => 'ap_id'
belongs_to :company, :foreign_key => 'ca_company_id'
end
app_pattern.rb
class AppPattern < ActiveRecord::Base
belongs_to :company_apps, :foreign_key => 'ap_ca_id'
end
_form.html.haml
= form_for(@company) do |form|
%table
%tr
%td
%h2 Company Apps
%td
- companyApps = @company.company_apps
- tags = Tag.order_by(:tag_title).all.collect{ |t| [t.tag_title, t.tag_id] }
- selected = Hash.new
- companyApps.each_with_index do |ca, idx_ca|
- options = options_for_select(tags, ca.tag_ids)
- html_options = { :multiple => true, :size => 8, :class => 'chosen', 'data-placeholder' => 'Select Tags'}
%tr
%td
=label_tag ca.ca_name
%td
= select_tag "tag_ids[#{ca.ca_id}][]", options, html_options
%tr
%td
- categories = [['category1', 1], ['category2', 2], ['category3', 3], ['category4', 4], ['category5', 5], ['category6', 6]]
- options = options_for_select(categories)
= select_tag 'company[category_ids][]', options, :prompt => "Select Category"
%tr
%td
%h5 App Patterns
%tr
%td
%h2= form.label ca.app_patterns, "App Pattern Name:"
=form.text_field ca.app_patterns
%tr
%td
%h2 Save Button
%td.submit= form.submit("Save", :class => 'submit')
%tr
%td
%h2 Cancel Button
%td.submit= button_link("Cancel", companies_path, 'submit')
Do I need to add another nested attributes statement to one of my models? How do I arrange the form correctly? Currently, I am getting the following error:
undefined method `#<AppPattern:0x007f8ee71525e8>' for #<Company:0x007f8ee713b0a0>
I currently have an order by working on my Ruby on Rails application so that on the Bookings index a user can order their bookings by show_date. This is done through the following in the bookings_controller:
def index
@bookings = Booking.joins(:showing).all.order(params.fetch(:sort, 'id asc'))
end
And the view code:
<form>
Order by:
<select name="sort">
<option value="show_date ASC">Show Date (Oldest First)</option>
<option value="show_date DESC">Show Date (Most Recent First)</option>
</select>
<button>
Go
</button>
</form>
But what I want to do is enable the user to order by the film's title as well as the show date. I have tried to do this with this code:
views/bookings/index.html.erb:
<form>
Order by:
<select name="sort">
<option value="show_date ASC">Show Date (Oldest First)</option>
<option value="show_date DESC">Show Date (Most Recent First)</option>
<option value="title ASC">Film Title (A-Z)</option>
<option value="title DESC">Film Title (Z-A)</option>
</select>
<button>
Go
</button>
</form>
And the bookings_controller:
def index
@bookings = Booking.joins(:showing, :film).all.order(params.fetch(:sort, 'id asc'))
end
But this doesn't work and I get the error:
ActiveRecord::StatementInvalid in Bookings#index
SQLite3::SQLException: no such column: film:
SELECT "bookings".* FROM "bookings" INNER JOIN "showings" ON
"showings"."id" = "bookings"."showing_id" ORDER BY film ASC
I think it is because their isn't an association between bookings and film.
Booking.rb:
belongs_to :user
belongs_to :showing
delegate :screen, to: :showing
Showing.rb:
belongs_to :film
has_many :bookings
belongs_to :screen
Film.rb:
has_many :showings
belongs_to :certificate
belongs_to :category
I'm having trouble with translations (I18n) in Rails 3. There are a couple of words that I can't realize from where Rails/I18n is trying to read the translation.
My form has a simple_form inside a custom_form. Something like this:
<%= custom_form_for(@prospect) do |f| %>
<div class="row-fluid">
<div class="span4">
<%= f.input :usuario_id, :wrapper => :prepend, :label => false do %>
<%= f.label :usuario_id, :class => "add-on", :required => false %>
<%= f.input_field :usuario_id, :collection => @usuarios %>
<% end %>
</div>
<%= f.simple_fields_for :crm_dados_entidade_attributes do |cde| %>
<div class="span4">
<%= cde.input :origem_lead_id, :wrapper => :prepend, :label => false do %>
<%= cde.label :origem_lead_id, :class => "add-on", :required => false %>
<%= cde.input_field :origem_lead_id, :collection => @origem_leads %>
<% end %>
</div>
<% end -%>
</div>
<% end -%>
I have translation files for each model. For example: prospects.yml, leads.yml, and son on...
My problem is that the fields in the custom_form_for are translated correctly, but the fields in the simple_fields_for are not translated. Actually, the output for origem_lead_id is: 'Origem lead', when my translation file is like this:
pt-BR:
activerecord:
models:
'crm/crm_dados_entidades': 'Pessoa'
attributes:
'crm/crm_dados_entidade':
origem_lead_id: 'Origem do Lead'
origem_lead: 'Origem do Lead'
I've tried to put this code in several files and in different ways, like (prospects.yml, crm_dados_entidades.yml), attributes for ( 'crm/crm_dados_entidade', 'crm/prospects').
Nothing seems to work. So, my question is: Is there anyway to track where Rails/I18n is looking for the translation?
Im following this tutorial. http://ift.tt/1kmdoqc i just the part titled Adding Some Validations to the User Model
When i go to http://localhost:3000/users/new i get an routing error. But based on my knowledge the rout looks fine. Whats wrong?
user_controller.rb
class UsersController < ApplicationController
def new
@user = User.new
end
def create
@user = User.new(params[:user])
if @user.save
flash[:notice] = "You signed up successfully"
flash[:color]= "valid"
else
flash[:notice] = "Form is invalid"
flash[:color]= "invalid"
end
render "new"
end
end
routes.rb
Rails.application.routes.draw do
get 'users/new'
Does anyone have any experience with upgrading the Casein gem when they upgrade to Rails3?

I don't know why it's not seeing the method and don't know if I'm meant to change the default :from => casein_config_email_from_address or not?
class Counter
def self.counted_new
@count = 0 if @count.nil?
@count += 1
new
end

@count
end
end
In format, @count looks like a instance variable, but when I load this in "irb"(interface ruby) and type four command code
Counter.counted_new
Counter.count
Counter.counted_new
Counter.count
@count finally became 2! acting like a class variable

I have an array of elements which are being displayed with their repective images using thumbnail defined through paperclip. When the data is replicated through .clone method of jquery everything is fine but the image does not show as per the thumb.Instead it shows the original size.
var clone = $('.pick.cloner').clone().appendTo('.picks-wrap .inner');
$(clone).data('id', data.picks[pick][1]);
$(clone).find('strong').html("Pick " + data.picks[pick][2]);
$(clone).find('p').html(data.picks[pick][3]);
$(clone).find('img').attr('src', data.picks[pick][4]);
$(clone).addClass('entering').removeClass('cloner');
My html
.inner
.pick.cloner
%em.selecting
Selecting
%em.ondeck
On Deck
%strong
Pick #
= image_tag("default_small_logo.jpg")
%p
Team Name
- @league.draft.get_picks(12).each_with_index do |pick, index|
.pick{ :class => "#{'selecting' if index == 0 && @league.draft.running?}#{'ondeck' if (index == 1 && @league.draft.running?) || (index == 0 && !@league.draft.running?)}"}

In firebug
Step 1: When the page is loaded or refreshed
<img alt="My image" src="http://ift.tt/1EuxjA8">
Step 2: When the clone is called the image source becomes like this
<img alt="My image" src="http://ift.tt/1wjk4v3">
How does it changes the thumbnail from "draft" to "original" I am not able to understand that neither am I able to debug the source of image that it is picking up or changing. It would be really great if someone helps.
I have an error, when try to run command:
rails g active_admin:install
The error is /home/user1/.rvm/gems/ruby-2.1.4@rails418/bundler/gems/active_admin-6bde1f57ec5f/lib/generators/active_admin/devise/devise_generator.rb:21:inrescue in install_devise': uninitialized constant ActiveAdmin::Generators::DeviseGenerator::DependencyError (NameError) ` Active admin and devise gems are install. The only problem is when I generate active admin. I use Rails-4.1.8 and ruby-2.1.4.
Thanks for help and good day.
Today, I found a very strange issue while writing a mountable engine using Rails 3. I have the following ApplicationController in my engine:
module Marketplace
class ApplicationController < ::ApplicationController
before_filter :merge_abilities
layout 'marketplace/application'
def marketplace_current_user
Marketplace::User.find(current_user.id)
end
private
def merge_abilities
current_ability.merge(Ability.new(current_user))
end
end
end
And my User model definition is
module Marketplace
class User < ::User
devise omniauth_providers: [:facebook, :paypal]
has_one :payout_identity, class_name: "Marketplace::PayoutIdentity"
has_many :course_purchases, class_name: "Marketplace::CoursePurchase"
def has_verified_payout_identity?
self.payout_identity and self.payout_identity.receiver_id
end
end
end
After starting up the rails server, the first request to load a page will have the controller run the marketplace_current_user method correctly and load the engine's User class. However any request after the first one will given a strange NameError - "uninitialized constant Marketplace::Marketplace::User".
I tried removing the namespace in marketplace_current_user definition but it will load the main app's User class instead.
At last when I change my ApplicationController to look like this:
class Marketplace::ApplicationController < ::ApplicationController
before_filter :merge_abilities
layout 'marketplace/application'
def marketplace_current_user
Marketplace::User.find(current_user.id)
end
private
def merge_abilities
current_ability.merge(Ability.new(current_user))
end
end
Everything would work fine.
Could someone enlighten me where I got it wrong at the beginning? Was it wrong to do inheritance that way?
Everything was working fine but I added stuff to my original scaffold, Specifically this line of code. "rails g migration add_first_name_and_last_name_to_users first_name:string last_name:string bio:text" After this I did "rake db:migrate" and added the fields. After working out the error I can't get past this new one.

I have a rails app with an audio player that plays an audio file stored in S3. The player works locally, but not in production (Heroku). The linked audio file plays fine when pasted in the browser. I am not posting code because I don't know where the problem is (if it is a code problem) and besides it works locally.
Anyone give me a gut feeling about what is happening?
After upgrading to Rails 4.2.0 from Rails 3.2.12, the following code in module WfHelper is broken:
def self.included(base)
base.before_action :load_wf_action_def
end
Here is base is the quotes controller. Method load_wf_action_def runs a eval to include some methods to make them available to quotes controller. In quotes controller, there includes:
include BizWorkflowx::WfHelper
None of the methods supposedly loaded by load_wf_action_def was there for quotes controller.
Which new feature in rails 4.2 could break the code? In debug, the QuotesController.public_instance_methods in Rails 4 does not return _one_time_conditions_valid_# which is imposed by execution of filter (action in Rails 4). In Rails 3, it does show the _one_time_conditions_valid_# for the before_filter executed.
I'm trying to use angular to send a file as a param to rails, and then have rails save that file as a user attachment via paperclip. The furthest I've gotten is getting rails to upload something, but it ends up being a txt file with the single line 'object file'.
Here's the relevant Angular
a.uploadAnonRes = function(app){
if(window.FileReader){ console.log("supported")};
console.log(($('.anonUploadField'))[0].files);
http = {
method: "PUT",
url: '/admin/upload_anon_res.json',
params: {
anon_file: btoa(($('.anonUploadField'))[0].files[0]),
user_id: app.raw_app.user_id
}
};
$http(http).success(function(data){
console.log("success");
});
};
Here's the relevant rails
def upload_anon_res
user = User.find(params[:user_id])
user.anon_resume = decode_res
user.save
respond_to do |format|
format.json{ render json: user, root: false }
end
end
def decode_res
decoded_data = Base64.decode64(params[:anon_file])
data = StringIO.new(decoded_data)
return data
end
As a last note, the file types that I'm trying to work with are doc/docx. I'm trying to avoid adding new dependencies, but if there's no other good way, then so be it. I really appreciate any help/suggestions.
Hey I am attempting to spawn a sidekiq worker that connects to a completely separate Redis database. I know with 3.0's connection pooling this is possible, and I have been able to successfully push a job onto the correct Redis DB, but the problem is the Sidekiq web UI is not showing these jobs in the queue (I have mounted a separate Rack app for this that points exclusively to the other Redis DB). The "Busy" tab in the admin interface also shows my sidekiq workers that I have pointed at this DB, with correct PIDs.
Here's my sidekiq.rb:
Sidekiq.configure_server do |config|
if ENV['REDIS_DB'] == "2"
config.redis = { :url => "http://redis#{SIDEKIQ_HOST}:6379/2", :namespace => 'drip' }
else
config.redis = { :url => "http://redis#{SIDEKIQ_HOST}:6379", :namespace => 'drip' }
end
end
Sidekiq.configure_client do |config|
if ENV['REDIS_DB'] == "2"
config.redis = { :url => "http://redis#{SIDEKIQ_HOST}:6379/2", :namespace => 'drip' }
else
config.redis = { :url => "http://redis#{SIDEKIQ_HOST}:6379", :namespace => 'drip' }
end
end
My use case is that I need to have fine grain control over the jobs that go into the second database, so I need the workers configured precisely so they are only using as many resources as I need them to. I only want the workers that are configured in this way to pick up these jobs.
I have an application which uses Sidekiq. The web server process will sometimes put a job on Sidekiq, but I won't necessarily have the worker running. Is there a utility which I could call from the Rails console which would pull one job off the Redis queue and run the appropriate Sidekiq worker?
I have the following route:
resources :projects do
resources :uploads, :only => [:destroy] do
member do
get ':filename', to: :download, as: :download
end
end
end
download_project_upload GET /projects/:project_id/uploads/:id/:filename(.:format) uploads#download
Here's the relevant part of my upload model
class Upload
has_attached_file :item,
:url => "/projects/:project_id/uploads/:id/:style_:basename.:extension",
:path => ":rails_root/public/:class/:attachment/:id/:style_:basename.:extension"
The problem is when I go a URL like the following:
http://mysite/projects/3902/uploads/5634/some.file.withdots.pdf
I get a routing error. How can I resolve this? The route looks correct to me.
Note: I only get the routing error on files which have dots in the names. If the file has no dots or uses underscores the route resolves as expected. Renaming all filenames to parse the dots out is not an option.

Everything was working great before i installed rubyinstall 1.9.3.
Then my local server wasn't working when i tried to run a new website im making.
So i reverted back to ruby 2.1.5p273 by running rubyinstaller 2.1.5
Anyone know what the problem is?
Here is what my server looks like when once the above error started to appear on gitbash
I have some markup as follows:
<div class="form">
<input type="text" name="user[email]" id="user_email" data-validate="true">
<label data-content="Your email"></label>
</div>
I am currently using client_side_validations to check and edit the markup to:
<div class="form">
<input type="text" name="user[email]" id="user_email" data-validate="true">
<label data-content="Your email"></label>
<span class="input-error" data-error-id="1">EMAIL IS EMPTY</span>
</div>
If, however, the user were to still submit the form somehow I would need to replicate the same behaviour from Rails' ActionView::Base.field_error_proc = Proc.new do |html_tag, instance| method. All I need to do is add a <span> tag, as above (the id isn't needed via Proc), to the end of the parent in which the <input> tag is contained.
How can I achieve this via Proc?

if this query is right help me framing this into rails query
So I am working on my first rails app and I can't seem to get past this error. I apologize if I don't provide enough information, I am still new to this stuff.
Here is the model I am trying to use:
class Movie < ActiveRecord::Base
attr_accessible :tilte, :rating, :description, :release_date
end
After a bit of searching, I discovered I should be able to force it to work if I disabled the white list by setting config.active_record.whitelist_attributes = false in the /app/config.rb which I did in an attempt just to bypass the issue for this assignment, yet I am STILL not able to mass assign attributes.
This is the specific error message that I am receiving: ActiveModel::MassAssignmentSecurity::Error: Can't mass-assign protected attributes: title
And here is the code I am trying to execute from the rails console:
#### Create
starwars = Movie.create!(:title => 'Star Wars',
:release_date => '25/4/1977', :rating => 'PG')
# note that numerical dates follow European format: dd/mm/yyyy
requiem = Movie.create!(:title => 'Requiem for a Dream',
:release_date => 'Oct 27, 2000', :rating => 'R')
# Creation using separate 'save' method, used when updating existing records
field = Movie.new(:title => 'Field of Dreams',
:release_date => '21-Apr-89', :rating => 'PG')
field.save!
field.title = 'New Field of Dreams'
#### Read
pg_movies = Movie.where("rating = 'PG'")
ancient_movies = Movie.where('release_date < :cutoff and rating = :rating',
:cutoff => 'Jan 1, 2000', :rating => 'PG')
#### Another way to read
Movie.find(3) # exception if key not found; find_by_id returns nil instead
#### Update
starwars.update_attributes(:description => 'The best space western EVER',
:release_date => '25/5/1977')
requiem.rating = 'NC-17'
requiem.save!
#### Delete
requiem.destroy
Movie.where('title = "Requiem for a Dream"')
#### Find returns an enumerable
Movie.where('rating = "PG"').each do |mov|
mov.destroy
end
Any advice?
There are various services like PandaStream and SublimeVideo that allow you to embed their service into your rails project. You can use their video players to show streaming content. I would rather design the user interface of the rails video player myself. Even though I've tried accomplishing this using stylesheets the video player never changes in the rails app. What is the proper way to customize the look of the default rails video player?
I am trying to use the HTML5 canvas features in a web application. Because there is image_tag and video_tag, I want to know if canvas_tag exist. If so, how do you implement it?
On Rails3, I have multiple gems which by default rely on YAML config files placed in conf/gem1.yml, conf/gem2.yml, etc; these files should not be checked into source control as they have user-specific values such as secret tokens.
I'm looking for a way for each gem to define a generator that will create an initial version of that file for each dev to modify afterwards, and have those generators registered somehow so they can all be run by invoking a single command.
For example, I'd like gem1, gem2 and gem3 to define gem1:config, gem2:config and gem3:config generators, as well as a shared gems:all_config. So if I include gem1 and gem2 in my project, I automatically have the gems:all_config generator that will invoke gem1:config and gem2:config; if I add gem3 later, gem3:config is automatically appended to the call to gems:all_config.
Any ideas on how to implement this cleanly? I've been playing around with hook_for with no success so far, as it seems to be designed for a different use case.
Here is the section of the controller that matters:
ap "START DATE IN THE CONTROLLER IS "
ap @selectedJob.start_date
@selectedJob.start_date = DateTime.strptime(@selectedJob.start_date.to_s, ('%m-%d-%Y'))
ap "AFTER THE STRPTIME METHOD"
ap @selectedJob.start_date
I wanted to know what the start_date was before and after my little method - I'm formatting the date part of the date object for display in a start_date input box in the view.
Here is the console output of the above:
"START DATE IN THE CONTROLLER IS "
Sat, 15 Feb 2014
"AFTER THE STRPTIME METHOD"
Fri, 14 Feb 2014
Why is Datetime.strptime subtracting a day from my date object?
When I change DateTime to Time class and call strptime - it correctly formats to Feb 15. What is it about DateTime that's not working and should I discontinue using it?
In my Ruby on Rails application I am creating a cinema system, and when a user is logged on they can click "My Bookings" which will list all of their bookings. (Note, when a user books a showing they choose the amount of adult seats, child seats, senior seats, and student seats). On this page I want to display the amount of seats the user booked for that showing, so rather than saying adult seats: 1, child seats: 3, senior seats: 2, it would display seats booked: 6.
I have started to create a method to do this in booking.rb model:
def user_booked_seats_quantity_for_showing
user = User.find(session[:user_id]).id
showing = booking.showing_id
self.where("user_id = ? and showing_id = ?", user, showing)
end
But am unsure how to get the method to add up the data in the attributes: adult_seats, child_seats, senior_seats, and student_seats, where the user_id is the user currently logged in and the showing_id is that particular showing.
Can anyone help?
It is also worth noting that this is for the views/bookings/index so if a user has multiple bookings it will list all of them.
I'm seeing very odd behaviour, where whether or not a filter is run seems to depend on whether it was set to run in the first spec to use that controller.
So I've reduced this down to a minimal controller:
class WtfController < ActionController::Base
before_filter :raise_error
def index
render nothing: true, status: 200
end
private
def raise_error
raise OMGError
end
end
(OMGError just subclasses StandardError)
And a test case:
describe 'wtfspec' do
it 'with filter' do
expect do
controller = set_up_controller
controller.process(:index)
end.to raise_error
end
it 'without filter' do
expect do
controller = set_up_controller
controller.class.skip_filter :raise_error
controller.process(:index)
end.not_to raise_error
end
end
def set_up_controller
controller = WtfController.new
controller.request = ActionController::TestRequest.new
controller.response = ActionController::TestResponse.new
controller
end
The filter should be skipped in the second test, but it isn't.
If the first expect block is not run, then the second test passes. It's only if it is run that the second fails. Similarly, if I skip_filter in the first test and use before_filter to readd it for the second test, the second fails to run the filter even though it should.
Here's the thing - if I examine the list of filters set on WtfController (using controller.class._process_action_callbacks.map(&:filters)) in the spec (in the second test) right before the controller.process line, then it has indeed been successfully removed, the skip_filter line works fine. But if I examine it inside the controller (in raise_error), it seems to have somehow been readded!
Note 'readded', not 'reappeared': The object_id of the raise_error callback that actually runs is different to the original one (the one that was there before running skip_filter). But the object_id of the array of filters (actually an ActiveSupport::Callbacks::CallbackChain) remains the same, as is the controller.
The behaviour is the same whether each of the two tests new's up a new controller object or reuses the same one (as you'd expect, since the filters are a property of the WtfController class object, not the instances).
I've spent a day debugging this and am utterly mystified. Any insight appreciated. Rails version is 3.2.21. Thanks :)
I am trying to disable asset fingerprinting by placing the following line in my config/environments/production.rb:
config.assets.digest = false
However, rails isn't honoring this and still compiling assets with a fingerprint in public/assets/:
bear-e1d6322cce5569e1c88e51d726af8f49.jpg
Why is rails ignoring this? Follow up question: if rails is stubborn about fingerprinting assets, why won't it change the name of the asset in the html.erb file so that the browser will know the right name of the file to request?
Summary:
I have a model with a few "belongs_to" associations and when I call Model.all (or another custom method if need be) I want to not only return all columns of Model, but also one column from each of the associated Models. Basically instead of just returning the ID's of the associated Models I want to get a more friendly attribute like "name".
Using Rails 3.2.x
Model Details:
I have five models, basically for data normalization.
class ActionItem < ActiveRecord::Base
belongs_to :action_item_status
belongs_to :prod_ops_acceptance
belongs_to :action_item_priority
belongs_to :incident_ticket
<truncated the rest>
end
class IncidentTicket < ActiveRecord::Base
attr_accessible :number
has_many :action_items
validates_presence_of :number
end
class ActionItemPriority < ActiveRecord::Base
attr_accessible :name
has_many :action_items
validates_presence_of :name
end
class ActionItemStatus < ActiveRecord::Base
attr_accessible :name
has_many :action_items
validates_presence_of :name
end
class ProdOpsAcceptance < ActiveRecord::Base
attr_accessible :name
has_many :action_items
validates_presence_of :name
end
Attempted Solutions:
I've tried many combinations of things including using ActionItem.includes and ActionItem.joins to no avail. The latest thing I tried is (trying only for the 'number' attribute of the IncidentTicket model to start with...)
ActionItem.all(
select: 'action_items.title, incident_tickets.number',
joins: 'INNER JOIN incident_tickets
ON action_items.incident_ticket_id = incident_tickets.id')
The above only returns the 'title' attribute from the ActionItem model and not the 'number' attribute from the IncidentTicket model despite the SQL looking correct. It seems like the SELECT on the joined table is completely ignored no matter what I try.
Obviously I am seriously missing something here or doing this completely wrong. I feel like there is some ActiveRecord magic that I'm missing out on that makes this trivial. Any help would be much appreciated! Please let me know if you need more details, I feel like this is kind of difficult to explain...
I'm very new to sqlite3 and can't seem to figure out how to get it to create tables.
I have the code for a Rails app that I am updating to Rails 3.0.3 from Rails 2.3.12. I had managed to get the database working when it was still Rails 2.3.12, however since I upgraded Rails it seems to have 'lost' the tables and I can't figure out how to recreate them.
When I do bundle exec rake db:create it says that the test and development databases already exist.
However, when I do bundle exec rake db:migrate it says
rake aborted!
Could not find table 'comments'
All of the migration files are still there, as is the schema, but I don't know how to create the tables?
I am quite new at rails and I am having some trouble designing an admin dashboard.
What I want to achieve is this:
Have a list of multiple users from database.
Have the ability to select multiple records.
Have the ability to apply different actions to all of the selected records.
The actions MAY not be directly translatable into SQL queries. (for example send an email)
I am not looking for a complete solution to the problem just a general description on how to approach this. I have a feeling I started on a wrong path.
So far I am doing this:
view
<%= form_tag("some_path", method: "get") do %>
<% @users.each do |user| %>
<%= check_box_tag "user_ids[]", users.id %>
<%end%>
<%end%>
controller
def send_email
@recipients = User.find(params[:user_ids])
@recipients.each do |recipient|
Notifier.raw_email(recipient.email, params[:user_email][:subject], params[:user_email][:body]).deliver
end
end
This works as it is but i can only apply one action, send email that is. I want to be able to choose an action to apply to all selected records or apply multiple actions to the selected records
Any thoughts?
I have to put piece of code, that won't be removed by parser or anything else. In my html version code looks like <span>[~username]</span> How do i write something similar? I only need to save [~username] part, because thats what parser removes(square brackets) and my code doesn't work
I have an Exam model. I want to get all records that satisfy a condition in an instance variable.
I tried this in my controller:
@exam_list = Exam.all
@exams = []
@exam_list.each do |exam|
if conflict?([current_exam.exam_date, current_exam.end_date],[exam.exam_date, exam.end_date])
@exams << e
end
end
But its not working.
I am having challenges assigning a current user a role in a team the user is creating. I want to assign the user that creates the team the role of the captain which could be changed later.
I'm currently using the create_asociation method that comes with has_one relationship, as this instantiates the values of the associated model, which i want to be instantiated with the current user but get the error Can't mass assign protected attribute: captain. Captain is a self join model with user as i will like to use captain.teammates and team.captain. Below are the models involved.
User and Captain Model
class User < ActiveRecord::Base

The admin is currently a way i'm using to restrict the user that can create a team but i plan to use gems like declarative authorization to create role based authorization. Thanks
In my Ruby on Rails application I currently have the methods:
def remaining_seats
seats.count - bookings.sum(:seats_quantity)
end
def screens_info
"#{name} (#{remaining_seats}/#{seats.count} remaining)"
end
Which return the amount of seats that are available to be booked, for example if there have been two bookings which have booked 6 seats each in a 20 screen cinema it'll say there are 8/20 remaining.
What I want to do is use this so that in this drop down menu where the user selects the amount of seats they require:
<%= f.select :seats_quantity, '1'..'10' %>
Rather than having the range 1-10 the user can only select a quantity up to the amount of seats remaining. So, from the above example, if there are 8 seats available the user could select up to 8 seats from the drop down menu.
Ideally what I would like is to have a restriction of the maximum amount of seats being selected as 10, then if there are 9 available it would go to 9 or if there are only 3 seats available it would have the maximum of 3.
How can I do this?
In my cinema ruby on rails application I am trying to display the amount of seats that have been booked for a showing in a screen. I have taken code from this question: Count the amount of records are associated to another record
And so have added this code to my screens.rb model:
def remaining_seats
seats.count - ( bookings || [] ).count
end
def screens_info
"#{name} (#{remaining_seats}/#{seats.count} remaining)"
end
And display this on the view:
<%= @booking.showing.screen.screens_info %>
But the code in remaining_seats: ( bookings || [] ).count returns 0, so the whole thing will tell me all seats are available.
This is my screen.rb model:
class Screen < ActiveRecord::Base
has_many :seats
has_many :showings
has_many :bookings, through: :showings
def screens_info
"#{name}"
end
def self.showing_search(showing_id)
if not showing_id.blank?
screen = Showing.find(showing_id).screen_id
self.where("id = ?", screen)
end
end
def remaining_seats
seats.count - ( bookings || [] ).count
end
def screens_info
"#{name} (#{remaining_seats}/#{seats.count} remaining)"
end
end
showing.rb:
class Showing < ActiveRecord::Base
belongs_to :film
has_many :bookings
belongs_to :screen
end
booking.rb:
class Booking < ActiveRecord::Base
belongs_to :user
belongs_to :showing
end
And the schema:
create_table "seats", force: :cascade do |t|
t.string "seat"
t.integer "screen_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "showings", force: :cascade do |t|
t.date "show_date"
t.time "show_time"
t.integer "film_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "screen_id"
end
create_table "screens", force: :cascade do |t|
t.string "name"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "bookings", force: :cascade do |t|
t.integer "user_id"
t.integer "showing_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "seats_quantity"
end
So just to clarify, what I am trying to do is display the amount of seats that are available to be booked for a particular showing in a specific screen - so say a screen has 25 seats and at the 13:00 showing 5 seats have been booked I want to say there are 20 seats remaining.
In my Ruby on Rails application I am creating a cinema system, and on the bookings/new page I am allowing the user to choose the amount of seats they require through a drop down menu. But what I want to do is display the number of seats that are currently free in the screen, for example if a screen has 50 seats and 7 have been booked I want the system to display: "There are 43 seats available." I know I will need a method for this but am unsure about how I would implement it and how I would show this message.
It is worth noting that a seat would only be booked for one showing, so it would be free for others, which means that the method would have to be able to count the amount of seats available for that showing.
Can someone please help.

end

It is worth noting that whilst the seats table contains the attributes row_letter and row_number a user IS NOT booking a specific seat, just the quantity of seats they require.
I am a newbie in Ruby. Please explain how the * operator works in this case.
arr = [1,2,3]
p arr
arr = *[1,2,3]
p arr
*arr = [1,2,3]
p arr
arr = [1,2,3]
p *arr
OUTPUT
[1,2,3]
[1,2,3]
[1,2,3]
1
2
3
What is happening in the last case ? Is it behaving as a iterator ? Can anyone give an example as to how to use it ? Also why it has no effect in the second and third case ?

I am developing a Rails application for Examination management.
Exams can be created for a time period.
Exam model have the fields start_date:datetime and end_date:datetime
Exam creation is a 2 step process. In the first step all the exam details including start_date and end_date is given.
In the second step I want to list all exams that have a conflicting time period with the current exam so that the user can choose whether to continue or not.
Example:
Current exam:
Start date and time: "2015-02-23 10:30:00"
End date and time: "2015-02-23 13:30:00"
Conflicting exam:
Start date and time: "2015-02-23 12:30:00"
End date and time: "2015-02-23 14:30:00"
How is it possible?
Like php we can import all the functionality of a simple php file name as myfile.php in another file index.php using require "", require_once "", include "" and include_once "". Like this in ruby on rails I want to import a controller file name as products_controller.rb in a another controller file name as home_controller.rb . both files present in the app/controller directory. In shot i want to import a controller file in another controller file to use all the functions of included controller file
I am looking for ways to reduce the default code for models, controllers and views.
I have just created a model SearchDescription with two fields and with a controller and view. I need the default scaffolded index,show etc. Also the rspecs, but again completely default. Nothing special. Just the default.
But as it turned out I am current committing some 20 files that are with a completely default behaviour. Nothing special.
Is there a way to do it cleaner with less code actually being generated in the project, but rather "dynamically generated"?
For example just write the following thing in a config file: SearchDescription, field1, field2; with Controller; with views; with rspecs
and have this work by convention without actually generating the files?
I am writing a Rail 3 engine to add some marketplace functionality to an existing app. The existing app has an item description page and I am going to add some extra elements that will be used by the marketplace to that page. When the user visits the item page using the main app's route, I would like to use the engine's controller and view to render the page so that the new elements will be displayed. Effectively the engine will override some of the main application's routes. Can this be achieved?

I have this route:
delete 'basket/remove' => 'flowercard_baskorder#remove', as: :basket_remove
This link in view:
<%= link_to "Remove", basket_remove_path %>
And this in my controller (the binding is just for me to test):
def remove
binding.pry
end
When the link is clicked on nothing happens and i have no idea why!? I'm obviosuly expecting the binding to kick in but doesn't even look like a request is made?

In my Ruby on Rails application I am trying to display a three drop down menus in the _form.html.erb which are rendered from the file _booking_lookup.html.erb and get there data from the drop down menu methods in the models.
_form.html.erb:
<%= render(:partial => '/booking_lookup', :locals=> {:film => @film = Film.all, :showings => @showings = Showing.all, :seats => @seats = Seat.all, :my_path => '/films/booking_lookup' }) %>
_booking_lookup.html.erb:
<%= form_tag my_path, :method=>'post', :multipart => true do %>
<%= select_tag ('title_id'),
options_from_collection_for_select(@films, :id, :title_info, 0 ),
:prompt => "Film" %>
<%= select_tag ('showings_id'),
options_from_collection_for_select(@showings, :id, :showing_times, 0 ),
:prompt => "Showings" %>
<%= select_tag ('seat_id'),
options_from_collection_for_select(@seats, :id, :seats_available, 0 ),
:prompt => "Seats" %>
<%= submit_tag 'Search' %>
film.rb:
class Film < ActiveRecord::Base
has_many :showings
belongs_to :certificate
belongs_to :category
def title_info
"#{title}"
end
end
seat.rb:
class Seat < ActiveRecord::Base
belongs_to :screen
has_many :bookings
def seats_available
"#{row_letter}#{row_number}"
end
end
showing.rb:
class Showing < ActiveRecord::Base
belongs_to :film
has_many :bookings
belongs_to :screen
def showing_times
"#{show_date.strftime("%e %b %Y")} @ #{show_time.strftime("%H:%M")}"
end
end
But for some reason with the line: <%= select_tag ('title_id'), options_from_collection_for_select(@films, :id, :title_info, 0 ), :prompt => "Film" %> I get the error:
NoMethodError in Bookings#new
undefined method `map' for nil:NilClass
The weird part is that I am using a lot of this code else where, I have a _multi_search.html.erb form:
<%= form_tag my_path, :method=>'post', :multipart => true do %>
<!-- Genre: -->
Search By:
<%= select_tag ('cat_id'),
options_from_collection_for_select(@categories, :id, :category_info, 0 ),
:prompt => "Genre" %>
<%= select_tag ('cert_id'),
options_from_collection_for_select(@certificates, :id, :certificate_info, 0 ),
:prompt => "Age Rating" %>
<%= text_field_tag :search_string, nil, placeholder: "ACTOR" %>
or
<%= select_tag ('title_id'),
options_from_collection_for_select(@films, :id, :title_info, 0 ),
:prompt => "Film" %>
<%= submit_tag 'Search' %>
<% end %>
And is used in the application.html.erb:
<%= render(:partial => '/multi_search', :locals=> {:categories => @categories = existing_genres, :certificates => @certificates = Certificate.all, :films => @films = Film.all, :my_path => '/films/multi_find' }) %>
And that works fine.
What am I doing wrong?
