RESTfully Nesting Resource Routes with Single Identifiers

Question

In my Rails app I have a fairly standard has_many relationship between two entities. A Foo has zero or more Bars; a Bar belongs to exactly

Answer 1

Rails' shallow nesting gives us the best of both worlds: it lets us have Foo-specific routes where it makes sense (create, new, index) and Bar-only routes otherwise (show, edit, update, destroy).

Unfortunately, the new routing DSL in Rails 3 (which I'm using) does not support shallow routing yet (as of Beta 3). It appears to be in the works but it's not functional for today.

However, you can fake it by mapping the resource twice, once nested and once shallow:

resources :foo do
  resources :bar, :only => [:index, :new, :create]    
end
resources :bar, :only => [:show, :edit, :update, :destroy]

This will tide me over until the :shallow option is up and running again.
