Hello,
Hope no one minds me just jumping in here with a question.
I'm completely new to Ruby on Rails. I've been reading "Simply Rails 2", and following their examples. I reached a point where the unit tests were unexpectedly failing. Upon investigation, I discovered that when Rails loads the fixtures, the foreign keys aren't being populated with the foreign record's ID, but instead is simply 0 (discovered this by looking at the tables manually).
The example has two models: stories and votes. One story-->many votes relationship.
The stories fixture: one: name: My shiny weblog link: http://poocs.net/
two: name: SitePoint Forums link: SitePoint Forums | Web Development & Design Community
The votes fixture: one: story_id: one
two: story_id: one
three: story_id: two
four: story_id: two
You'd expect that 'story_id' for two of the records in the votes table would be set to the corresponding ID for the first story, and so on, but what we find instead is that for all the records, the story_id is zero (which is why some of my assertions fail, since it can't find the votes that should be associated with a given story).
Presumably, I've made an error in either my fixtures or the models, I've gone back over their examples and haven't been able to find it; presumably I'm not seeing it for the forest or something. The models, in case the error is there:
class Story < ActiveRecord::Base validates_presence_of :name, :link has_many :votes do def latest find :all, :order => 'id DESC', :limit => 3 end end def to_param "#{id}-#{name.gsub(/\W/, '-').downcase}" end end
class Vote < ActiveRecord::Base belongs_to :story end
Thanks,
Iain
