Trying to convert my app (and brain) to RESTful routes from the old
style. What is the accepted approach to nesting a resource within 2
other resources?
Example:
Models
Person has_many :scores
Contest has_many :scores
Score belongs_to :person, :contest
Routes
resources :people do
resources :scores
end
resources :competitions do
resources :scores
end
I want to be able to list scores by person, or by competition. Either
of the these two paths will request the :index action in the :scores
controller:
GET /people/person_id/scores
GET /contests/contest_id/scores
So what is the best way to structure scores/index to deliver the
appropriate list?
I could test for the presence of params[person_id] or
params[contest_id], then execute and render accordingly within
the :index action. But that seems somewhat inelegant. Is there a
better way? Should I have two separate actions within the :score
controller, and modify my route mapping somehow to request the
appropriate action?

But that seems somewhat inelegant.How about writing something generic to get the parent? You can add this at the bottom of your ScoresController for example: private def get_parent params.each do |name, value| return $1.classify.constantize.find(value) if name =~ /(.+)_id$/ end nil end Have fun, Franz -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

It tells you nothing about the implementation details of how to structure your controllers, which seems to be your real question here.> > Example: > > Models > > Person has_many :scores > Contest has_many :scores > Score belongs_to :person, :contest > > Routes > > resources :people do > resources :scores > end > > resources :competitions do > resources :scores > end > > I want to be able to list scores by person, or by competition.

I think I''d use the former solution, though.

What is the difference between persons and contests as far as scores are concerned? Looks to be a polymorphic relationship based on the context of your post. Person to Scores and Scores to Contest. I agree with radhames, though in lower case. I''ve found that you need only be concerned with one level of nesting at a time.
