Hi, I''m really excited about getting the create() method working on a nested hash. The Rails book make it seem like I''m close to doing the right thing but I think something very small is not quite right. The error at the below isn''t giving any hints that I understand. I have a form that produces a nested params hash and sends it to my add_to_cart controller method.

trying to set up a "has_and_belongs_to_many" relationship would very much appreciate the help, not sure what im doing wrong at all. Scheme.rb class Scheme < ActiveRecord::Base validates :schemename, :presence => true belongs_to :user has_many :levels, :dependent => :destroy has_and_belongs_to_many :works end Work.rb class Work < ActiveRecord::Base

Hope someone can tell me what''s up, because this has me baffled. I have an Image model, and a Provider model. Both are defined as "has_and_belongs_to_many" relating to each other. In my image form partial, I have a bit of AJAX generating the provider_ids array dynamically from a provider AJAX search on the same page. So for example, each time I click on a provider name that

Most times I look up a list of books I want to know a page reference for each one, so the views that display booklists expect an array of two-element arrays, constructed via a method in the model like so: (class Category) def book @book = Array.new self.bookshelves.each { |x| @book << [x.book, x.pages] } return @book end When I get the list of all books that a user has

I''ve been stumped on this for a few days and I''m not sure if it''s an error on my end or an actual bug. I have a system where I have workshops and users. Workshops have students, presenters, and troubleshooters. I wanted to represent this simply by using has_many :through with :source. Workshop has_many :presenters, :through =>:presenterships, :source=>:user

Hi Just curious if anyone can explain why using a dynamic find fails to work with << operator I have standard habtm relationship class User < ActiveRecord::Base has_and_belongs_to_many :roles Now when I assign a Role via << after saving the new User I get wierd behaviour but only when using the dynamic version of find i.e @user = User.new(p) if @user.save #

Hi all ! I''ve written a Character model, each character has many Attributes. My schema.rb looks like this: create_table "characters", :force => true do |t| t.string "first_name" t.string "last_name" t.integer "user_id" t.datetime "created_at" t.datetime "updated_at" end create_table "attributes",

Hey guys & ladies! I''ve got the following relationship which i''m trying to get accepts_nested_attributes to work with. But when i submit my form, it looks as if its expecting a Company object, rather than an array of companies. which really doesn''t make sense considering its a has_many :relationship. So what i''m after, is a way to

Hi all I want to overwrite the push method (which is an alias of <<, the same as concat) of collections, and there I want to test if :uniq is set to true in the relationship. If so, the method should check if the passed object is already related to the parent, or not (only then it will be added). But I just can''t find the original code of this method, so I could overwrite

In my continued efforts to port my rails 1.x app to Rails 2.1.2, I keep running into what appear to be ActiveRecord bugs.
