Hi. I''ve tried to redefine the method belongs_to in ActiveRecord::Base, so every time a model is defined as belonging to :attachment, it should have some additional methods. I tried to do an alias of belongs_to, but this was not successful. The error message in Webrick was > Booting WEBrick... ./script/../config/../lib/ActiveRecordExtensions.rb:67: undefined method

I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

I''ve been using this sort helper to have sortable tables. http://wiki.rubyonrails.com/rails/pages/Sort+Helper I''ve encountered a situation where I need to sort a column that is not part of a table, but it''s related table. For example, say I have db tables called foos and bars. Foos have fields called name and title. And bars have fields called note and foo_id. Foos

In a belongs_to association, is there a way to tell if the associated object was newly created? Hopefully this will explain my question: A Firm class declares has_many<http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethods.html#M000530>:clients and a client class declares

Hello, I needed to add custom cache field for one of my application. I thought I will share the code showing how to do this. This code below creates and maintain a custom cache field, for keeping track of totals. Say, you have accounts, and for each account there are transactions (either deposit/withdrawal), and one will like to keep track of the total balance for an account. So, let there be a

hello, I''m using the trunk versions of both plugins. I''m running into this error when I run a migration to try and create the versioned table for the model ''Note'' stack level too deep /Users/Adam/dev/sweetspot/app/trunk/config/../vendor/plugins/ acts_as_paranoid/init.rb:5:in `belongs_to_without_deleted''

Hi. I get some strange results when using rename_column on a primary key in a migration. It seems like the migration script removes the auto-increment property if you rename a column. This is a minimal example. create_table :foo, :primary_key => :foo_id do |t| t.column "name", :string end # renaming the primary key makes auto-increment disappear. rename_column

I''m still fairly novice when it comes to rails so i was hoping someone here could shed some light on the correct way to do things. I have a central object that has :has_many relationships with 5 other objects. So i have one table, foo, and 5 other tables have foo_id to associate each row with a foo object. Now, i have a page that renders all the "foo" associations. I chose

I am applying Rails to an existing schema and not sure how much the existing developers will let me go in and rename things. So I need to discover the limits of what I can change with Rails. I''ve found set_table_name and set_primary_key, which have been very useful. If I have a "foo has_one :bar" relationship, but then in the bar table my column is named "fooid"

I''m trying to figure out how to design a view and controller to work with a simple collection. I have a Foo that has many Bars, so here''s what I did: $ ruby script/generate model Foo $ ruby script/generate model Bar (Uncomment t.column, :name: :string in foo and bar migrations) (Edit Foo.rb and Bar.rb, add has_many :bars to Foo, belongs_to :foo to Bar) $ rake db:migrate $ ruby

url_for( :controller => ''foo'', :action => ''destroy'', :id => 1 ) => ''/ foo/1'' url_for( :controller => ''foo'', :action => ''destroy_x'', :id => 1 ) => ''/ foo/destroy_x/1 url_for( :controller => ''foo'', :action => ''destroy'', :foo_id => 1 )

I''m trying to set up a directional self-referential HABTM to represent an arbitrary semi-hierarchical structure; it works for any data prepopulated into the db, but when I try to create a new relationship, I just get NULLs in both key columns (or 0''s if I turn on the no-null constraint). Here are the migrations: class CreateNodes < ActiveRecord::Migration def self.up

Hi all I want users to register on my page. To register, they only have to deliver an email and a password. Then a link with an activation token will be sent to them, and after clicking the link the user sees a page where he should fill in further details, means: a username.

Hi all, I have the following inside of an AR class definition: relationships=ActiveRecord::Base.connection.select_all(my_relationships_sql) relationships.each do |relationship| has_many RelatedItems, :class_name => relationship[''RelatedClass''], :foreign_key => relationship[''ForeignKey''] end This kind of works, but how can I assign the name of the

I have the following models: class Card < ActiveRecord::Base belongs_to :deck belongs_to :front, :polymorphic => true belongs_to :back, :polymorphic => true end class TextContent < ActiveRecord::Base has_one :card, :as => :front has_one :card, :as => :back end The conflicting has_one declarations don''t work. What I need is

I have a helper that uses some jQuery code that I would like to move out of the helper method. I am trying to move it to application.js but it will probably end up in a different file. I have two reasons for wanting to do this. 1) I want to keep all my jQuery code seperate to my HTML code 2) I want to change the append to an appendTo so I can add a highlight effect, appendTo which is proving

Hello List, I''m trying to generate examples for some list-helpers I have coded which use in my projects. Basically, the Playlist class uses one anonymous module in has_many that acts as helper between acts_as_list and my desired API: class Playlist < ActiveRecord::Base # associations go here has_many :playlist_items, :order => :position, :dependent => :destroy has_many
