I find it easier to debug model relationships in the console as
opposed to the browser... try (this is a guess as to your schema,
change attributes as needed of course)
q = Question.create :content=>"where's the beef?", :user=>"guest"
q.answer = Answer.create :content=>"in my belly", :user=>"fat bastard"
q.suggestions << Suggestion.create :content=>"look in the fridge"
When accessing these resources you'll probably want to only reference
an answer within the context of it's question. Your routes.rb file (in
config) should include:
map.resources :questions, :has_one => :answer\
I recommend you pick up 'Advanced Rails Recipes' and read Adam
Wiggins' recipe regarding nested resources. HTH.
