Controller inheritance and nested attributes Error

[Brian Jensen]

I have a LettersController with all my resource_controller logic in:

class LettersController < ApplicationController
resource_controller

#Logic in here
end

class FailedEnrollLettersController < LettersController
belongs_to :stay
#Empty class for now
end

When I point a browser to : http://localhost:3000/stays/1/failed_enroll_letters/new

I get the error:

Processing FailedEnrollLettersController#new (for 127.0.0.1 at
2009-07-13 21:07:47) [GET]

The LettersController is just a resource_controller I want multiple
controllers to inherit from to keep things dry, so its not in the
routes.rb

Nested resources ofcause, not attributes.

Have you declared that Stay has_many :letters?

[Brian Jensen]

No because it hasnt.

There is no Letter model. I just have a LettersController where all
the logic from CustomLettersControllers, ReviewLettersController is
in. And the two controllers inherit from the LettersController.

Thanks in advance.

Well, when you say belongs_to :something, resource_controller expects to be dealing with a hirearchy of active record models. If you haven't got a hirearchy of activerecord models, you need to either implement methods that mimic them, override the appropriate methods in your controller, or implement the controllers by hand.
