Hi,
I wonder if there''s an easy way to access the associated Model class
from its Controller. Something that would allow me to write snippets
like the following:
class PeopleController < ApplicationController
def some_method
person_model_class =
self.some_method_to_retrieve_the_person_model_class()
end
end
Cheers,
Marco

Controllers aren''t associated to one specific model. But yes, for general CRUD operations, you''ll usually just use one... So, this will probably do what you want: model = Object.const_get controller_name.camelcase The benefit is that you can have PeopleController < GenericController, and define generic CRUD things in the latter.

Although common practice to create one controller per model, there''s nothing to say there should be a one-to-one or indeed any relationship between models and controllers. One controller may deal with many models, one model may be used in many controllers. I''m guessing you want to do this to reuse code in some way. If so, perhaps if you explain which code you want to reuse the list can help come up with an appropriate strategy (abstract class, module, etc).
