Rails3: warning: toplevel constant ApplicationController referenced by

Everytime i get a warning:

app/controllers/agency/agencies_controller.rb:1: warning: toplevel constant ApplicationController referenced by Agency::ApplicationController

My agencies_controller.rb:

class Agency::AgenciesController < Agency::ApplicationController

  def index
    ...
  end 

  ...
end

And Agency::ApplicationController:

class Agenc开发者_高级运维y::ApplicationController < ApplicationController
  layout 'agency'

  helper_method :current_agency
  private

  def current_agency
    @current_agency ||= current_user.agency 
  end

end

What the rails wants from me? What is the trouble?

Same situation with another controller

class Agency::ClientsController < Agency::ApplicationController
  ...
end

And no warnings, no errors...

I realize this question is almost two years old but I recently stumbled upon this through another stackoverflow post and wanted to share some insight.

Basically, if your namespace Agency happens to be a class instead of a module, you'll get that warning. In the stackoverflow post I pasted above, they had a model (class) of Admin and their namespace was also Admin.

This provides a better explanation of what is happening.

So check to see if your code isn't defining an Agency class somewhere. Good luck.

I had similar issues running Spork and Watchr in my Admin namespaced controllers. So i've fixed this by adding following code into each_run block in spec_helper.rb:

Dir[File.expand_path("app/controllers/admin/*.rb")].each do |file|
    require file
end 

All credits goes to guy from this thread

ApplicationController is the name of the superclass controller that Rails generates for you when you create a new project that all your other controller classes inherit from. There's probably a conflict somewhere because you've used the same name, even though you put it within a namespace.

Try giving your Agency::ApplicationController a different name.

I had similar issues, after setting up Spork and Watchr. In the process, I turned off class cacheing (config_cache_classes => false in config/environments/test.rb) so that changes would be reloaded as necessary in the spork environment. Turning class cacheing back on made the warnings go away.

In my case it was the problem with Devise. I had a devise model Admin and a namespaced routes Admin. Changing the namespaced route to Admins solved the problem.

Solution for me was add this line:

# spec/rails_helper.rb
Dir[File.expand_path("app/controllers/admin/*.rb")].each { |file| require file }
