I''m trying to order a find through a has_many association. I have a model called SalesOrder. Each sales order has things like amount, description, etc. I use the following to get the Sales Orders: @sales_orders = SalesOrder.find(:all) And I display them with: <td><%= link_to sales_order.id.to_s, :action => ''show'', :id => sales_order.id

I have a problem that surfaced in my attempt to upgrade my application to Rails 1.1. We have a STI model on the "belongs_to" side of a has_many/belongs_to relationship. All my unit tests for this model pass, and the relationships all seem to work fine. But in my functional tests, I''m getting errors. I''ve traced it back into the call to the has_many

I have two models with a straightforward has_many / belongs_to relationship: class Premise < ActiveRecord::Base has_many :metered_services, :dependent => :destroy ... end class MeteredService < ActiveRecord::Base belongs_to :premise ... end and nested routes to match: Demo::Application.routes.draw do devise_for :users resources :premises do resources :metered_services

I''ve got a User model and a Book model. A user is required to submit books each month to be reviewed by other users. I have the following relationships defined: # the join model book_review.rb belongs_to :user belongs_to :book end book.rb # each book is reviewed by many users. This allows us to get the BookReview # objects associated with this book has_many :book_reviews,

People, I have gone through the cookbook example: http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=1 and everything worked fine an a FC4/Postgres setup. I then tried to reproduce this success with something that would be useful to me - a library db using books & authors tables. The author list works but NOT the book list (unless I take line #17 out). I get this message:

Hi All, I am using the file_column plugin to upload images. The model that I am using is simply called images (id, name, caption - name being the "file" column) and it belongs_to a parent model called books which has_many images. I was able to figure out how to enter the images into the correct model when updating of form of the parent model (books). Now I need to figure out

Hi All, This is my first post on this list. I''m a developer working on the Central Coast of NSW, Australia and came across RSpec via Lachie who demoed RSpec on Rails at a Sydney rails user group meeting a couple of months ago. I''m loving the expressiveness of RSpec and can''t really see myself going back to Test::Unit. I''ve come across one oddity though. I

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

I am trying to do something right from Agile Web Dev with Rails book and it does not work. I must be missing something obvious. I have a one-to-many relationship: class Draft < ActiveRecord::Base has_many :endorsees end class Endorsees < ActiveRecord:: Base belongs_to :draft end >From my reading, methinks I should be able to say: d = Draft.new d.endorsees << Endorsee.new

Hello folks! Beare with me for a second, while I explain my problem. Assuming we have the trivial model of class Author has_many :books end class Book end How do people go about creating the authors/edit and authors/new views if you want to be able to add and remove arbitrary amount of Books at Author creation and edit time? What I mean by this is that I go to

I''m stymied at how to create a fixture that establishes a has_many :through relationship. I''ve watched the railscast at: http://media.railscasts.com/videos/081_fixtures_in_rails_2.mov ... but that''s for HABTM relationships. I''ve read: http://www.ruby-forum.com/topic/145676 but that ultimately doesn''t answer any question. So with no further ado:

(This message was originally written on StackOverflow -- the formatting is much prettier there -- http://stackoverflow.com/questions/1283046/problem-with-setter-override-on-activerecord) This is not exactly a question, it''s rather a report on how I solved an issue with write_attribute when the attribute is an object, on Rails'' Active Record.

hello. first things first - I am new to ruby on rails (ruby, too), so I''m figuring this is just a basic newbie error. I''m creating a basic photography website.
