Not able to override helper.

I'm trying to upgrade an application to Rails 3 and I found a difference in the way helpers are loaded. I want to override a method based on the current controller but it now seems that all helpers are loaded.

I've broken it down to a simple example. I have a test app with 2 controllers - books and authors. In the BooksHelper module, I have:

module BooksHelper   def some_helper     "From books helper"   end end

In AuthorsHelper module, I have:

module AuthorsHelper   def some_helper     "From authors helper"   end end

In my index.html.erb for Books I include <%= some_helper %> and in index.html.erb for Authors I include the same <%= some_helper %>.

When I do the books index it shows as "From books helper" but when I do a authors index I get the same "From books helper" - I had hoped for "From authors helper". I tried the same app in rails 2 and I get the helper method from the current controller used - so I get what I expected.

In my real app - I have a call in the layouts - application.html.erb where I call the helper and hope to get the current controller's helper so I can show information (like bread crumbs) for the current controller.

That’s because Rails 3 implies helper :all.
