Rspec Controllers in and out of namespace with same name

Question

I have the following setup:

class UsersController < ApplicationController
...
end

class Admin::BaseController < ApplicationController
...
end

class A         


        

Answer 1

This happens when a top level class get autoloaded before a namespaced one is used. If you have this code without any class preloaded :

UsersController
module AdminArea
  UsersController
end

The first line will trigger constant missing hook : "ok, UsersController does not exist, so let's try to load it".

But then, reaching the second line, UsersController is indeed already defined, at top level. So, there's no const_missing hook triggered, and app will try to use the known constant.

To avoid that, explicitly require proper classes on top of your spec files :

#spec/controllers/users_controller_spec.rb:

require 'users_controller'

And

#spec/controllers/admin/users_controller_spec.rb

require 'admin/users_controller'
