I followed the steps in the following link literally in a new Rails
2.2.2 project
http://ryandaigle.com/articles/2008/3/24/what-s-new-in-edge-rails-has-one-through
Then I ran it in script/console, getting these error (actually I got
same error in another big rails project before I read that link):
NoMethodError: undefined method `update_attributes'' for #<Class:

I simply copied the code in that link, and in the associated table there were only needed fields to establish the relations.

Re: has_one :through doesn''t work in Rails 2.2.2
Maybe your defined rails version in environment.rb is not 2.2.2? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I was having the same issue as Clive trying to test the referenced example I was able to get some functionality by using :has_one subscription rather than :has_many. I do have a question though. I can set the through association like this user=User.create(:name=>"Bob") m=Magazine.create(:name=>''test'') user.magazine=m then user.subscription will = #<Subscription id: 1, user_id: 1, magazine_id: 1...> However, using user.update_attributes(:magazine=>m) the return is true, but there is no association created. Subscription remains nil. Am I wrong in assuming that I should be able to do this?
