  • How to override the attr_protected?

    - by KandadaBoggu
    I have STI implementation as follows: class Automobile < ActiveRecord::Base end class Car < Automobile end class Truck < Automobile end class User < ActiveRecord::Base has_many :automobiles accepts_nested_attributes_for :automobiles end I am creating a list of automobiles for a user. For each automobile, the UI sets the type field and the properties associated with the automobile.While form submission, the type field is ignored as it is a protected attribute. How do I work around this issue? Is there a declarative way to unprotect a protected attribute?

  • Newbie question attribute from associated table not showing up in index view

    - by Lauren
    Hi I know this is something simple I am doing wrong. I have three tables, installation, neighborhood, schools Installation: has_many :schools has_many :neighborhoods Neighborhood: has_many :installations has_many :schools Schools: belongs_to :installations belongs_to :neighborhoods I can't figure out how to show the name of the neighborhood the school is located in on the index view. I can get it to show on the show view once I have the school id. But on the index view I can't figure out what to put in the controller that will allow me to access the neighborhood name from the neighborhood_id that is in the School model. I am sure this is so easy and I am screwing up something stupid. HELP!

  • has_many relation doesn't seems right or logical, some thing like belongs_to_many looks right

    - by Vijendra
    My situation is like this. Company has many users and users may belongs to many companies. And current implementation is something like below. class Company has_many :employments has_many :users, :through = :employments end class Employment belongs_to :company belongs_to :user end class User has_many :employments has_many :companies, :through = :employments #This doesn't looks correct end User has many companies doesn't looks logically meaningful.It must be some thing like belongs_to_many companies. Do I need to use has_and_belongs_to_many? But that also will gives the same meaning. Can some one please suggest the right way for representing these relationships?

  • how to pass session variable to model in RoR?

    - by siulamvictor
    I used a global variable in my app for passing information before. But I got a problem and thanks everyone here suggested me to store those data in session with database. I tried, but I found that I can't access the session variable in Model. I googled and knew this is the Model normal behavior, RoR won't pass the session variable to Model. So how to pass the value of the session variable into Models? or is there any other method for my use case? I need a variable storing a value, which is required in all MVCs, and should be independent between different concurrent users. Thanks everyone. :)

  • Using fixtures with factory_girl

    - by deb
    When building the following factory: Factory.define :user do |f| f.sequence(:name) { |n| "foo#{n}" } f.resume_type_id { ResumeType.first.id } end ResumeType.first returns nil and I get an error. ResumeType records are loaded via fixtures. I checked using the console and the entries are there, the table is not empty. I've found a similar example in the factory_girl mailing list, and it's supposed to work. What am I missing? Do I have to somehow tell factory_girl to set up the fixtures before running the tests?

  • object.valid? returns false but object.errors.full_messages is empty

    - by user549563
    Hello I'm confuse about objects that I can't save, simplified model is class Subscription < ActiveRecord::base belongs_to :user, :class_name => "User", :foreign_key => "user_id" has_many :transactions, :class_name => "SubscriptionTransaction" validates_presence_of :first_name, :message => "ne peut être vide" validates_presence_of :last_name, :message => "ne peut être vide" validates_presence_of :card_number, :message => "ne peut être vide" validates_presence_of :card_verification, :message => "ne peut être vide" validates_presence_of :card_type, :message => "ne peut être vide" validates_presence_of :card_expires_on, :message => "ne peut être vide" attr_accessor :card_number, :card_verification validate_on_create :validate_card def validate_card unless credit_card.valid? credit_card.errors.full_messages.each do |message| errors.add_to_base message end end end def credit_card @credit_card ||= ActiveMerchant::Billing::CreditCard.new( :type => card_type, :number => card_number, :verification_value => card_verification, :month => card_expires_on.month, :year => card_expires_on.year, :first_name => first_name, :last_name => last_name ) end end and in my subscription_controller if subscription.save # do something else debugger # means breakpoint where i try subscription.errors.full_messages # do something else end I tried to use ruby-debug for this adding a breakpoint before. And subscription.valid? return false which explains that ActiveRecord doesn't allow the save method. Unfortunately i can't know why the object is invalid. subscription.errors.full_messages # => [] I'm stucked, if you have any idea, thank you.

  • How do I deactivate a specific version of gem?

    - by JayX
    Currently I have two versions of rack installed on my computer 1.0.1 and 1.2.1 However, when I tried to push my git to Heroku, it complains You have already activated rack 1.0.1, but your Gemfile requires rack 1.2.1. Consider using bundle exec. (Gem::LoadError) How can I deactivate rack 1.0.1 and activate 1.2.1 instead? (I can't uninstall 1.0.1 since it's under system folder and I don't have the root password)

  • How to add a has_many association on all models

    - by joshsz
    Right now I have an initializer that does this: ActiveRecord::Base.send :has_many, :notes, :as => :notable ActiveRecord::Base.send :accepts_nested_attributes_for, :notes It builds the association just fine, except when I load a view that uses it, the second load gives me: can't dup NilClass from: /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2184:in `dup' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2184:in `scoped_methods' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2188:in `current_scoped_methods' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2171:in `scoped?' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2439:in `send' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2439:in `initialize' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:162:in `new' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:162:in `build_association' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_collection.rb:423:in `build_record' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_collection.rb:102:in `build' (my app)/controllers/manifests_controller.rb:21:in `show' Any ideas? Am I doing this the wrong way? Interestingly if I move the association onto just the model I'm working with at the moment, I don't get this error. I figure I must be building the global association incorrectly.

    - by Daniel
    Hello: I have a note table with columns: title :string content :text rating :integer and a thinking_sphinx configuration: define_index do indexes :title, :sortable => true indexes :content end Then I can search the notes and assign weights to title and content to define the order or the result: Note.search "abc", :match_mode => :extended, :field_weights => { :title => 10, :content => 3 } Now I want to assign a weight to the rating column The type of the rating column is integer. The range of the rating is [1, 2, 3, 4, 5].

  • Scheduling a Delay Job on Heroku with a Worker Dyno

    - by user1524775
    I'm currently using Heroku's scheduler to run a script. However, the time that the script takes to run is going to increase from a few milliseconds to a few minutes. I'm looking at using the delayed_job gem to push this process off to a Worker Dyno. I want to continue to run this script once-a-day, just offload it to the worker. My current rake task is: desc "This task updates some stuff for you." task :update_some_stuff => :environment do puts "Updating some stuff ..." SomeClass.new.process puts "... done." end Once the gem is installed, migration run, and worker dyno started, will the script just need to change to: desc "This task updates some stuff for you." task :update_some_stuff => :environment do puts "Updating some stuff ..." SomeClass.new.delay.process puts "... done." end With this task still being a rake task scheduled by Heroku's Scheduler, is the only thing that needs to happen here the introduction of the delay method to put this in the Worker's queue? Thanks in advance for any help.

  • What is the best way to set default values in ActiveRecord?

    - by ryw
    What is the best way to set default value in ActiveRecord? I see a post from Pratik that describes an ugly, complicated chunk of code: http://m.onkey.org/2007/7/24/how-to-set-default-values-in-your-model class Item < ActiveRecord::Base def initialize_with_defaults(attrs = nil, &block) initialize_without_defaults(attrs) do setter = lambda { |key, value| self.send("#{key.to_s}=", value) unless !attrs.nil? && attrs.keys.map(&:to_s).include?(key.to_s) } setter.call('scheduler_type', 'hotseat') yield self if block_given? end end alias_method_chain :initialize, :defaults end YUCK! I have seen the following examples googling around: def initialize super self.status = ACTIVE unless self.status end and def after_initialize return unless new_record? self.status = ACTIVE end I've also seen people put it in their migration, but I'd rather see it defined in the model code. What's the best way to set default value for fields in ActiveRecord model?
