ActionController::RoutingError (uninitialized constant Users):

Question

I have added a t.boolean :admin field to my Devise migration file. It was saying that it was an unpermitted parameter in the console so I attempted to create a protected permitter for the :admin value when the form is submitted.

Here is my Users::RegistrationsController < Devise::RegistrationsController:

    class Users::RegistrationsController < Devise::RegistrationsController
      before_action :configure_permitted_parameters

      protected

      #Permitting the admin boolean
      def configure_permitted_parameters
        devise_parameter_sanitizer.permit(:sign_up).push(:admin)
      end
    end

And my routes.rb file with the devise_for method.

    devise_for :users, :controllers => { :registrations => "users/registrations" }

I cannot seem to fix ActionController::RoutingError (uninitialized constant Users): despite me looking on stack overflow for 30 minutes and trying to rename a couple of things. Any ideas?

Answer 1

Your controller has probably the wrong name or it is placed in the wrong folder. When following Ruby on Rails conventions then a controller named Users::RegistrationsController should be defined in a file named app/controllers/users/registrations_controller.rb.
