Question

The first layer is routing and the second layer the controller, so when in View, is there a way to dump out the path or filenames and line numbers of route and controller before reaching view?

I wanted to do this because www.example.com/stories/12345 is showing a page, but stories_controller.rb doesn’t have a def index or def show

Update: I guess it might be as if the program has an error, in which case it will show an application trace and a rails trace.

Answer 1

Well actually there is no other alternative than using a index or show and it has to be defined inside the class StoriesController. But it does not mean that those methods are defined inside the file “stories_controller.rb”.

There are a few options:

• they are defined in the ApplicationController from which it derives. Or there is another parent-class.
• for instance, when you use ActiveScaffold your controller contains a single line active_scaffold that adds all the standard CRUD actions (index, show, …)

To see where a method is defined, you could type inside your script/console session

StoriesController.new.method('index')

and it would return a set of classes/modules, as explained here.

For instance, in our ApplicationController we include a module that defines a method login_required, and that looks like this:

>> ApplicationController.new.method(:login_required)
=> #<Method: ApplicationController(PilgrimBase::Base::Authenticated)#login_required>

Hope this helps.
