'Generating Devise Controllers - Rails Devise

I am trying devise for the first time.I am following the link:https://github.com/plataformatec/devise. Here,i have executed the command:

rails generate devise MODEL

when i have executed this,the model and view parts are created.When i checked the routes,I have noticed that there is a controller created with the name:MODEL.but i didnot find the controller in the project.My query is how can we find whether a controller is generated or not and use that controller in the project. Thanks in advance.

Solution 1:[1]

running 

rails generate devise MODEL

when using the Devise gem will not create the controllers for you.

In your case, if you want to change any methods in the Devise controllers, you may want to create your own controller that inherits Devise controllers.

For example, changing the devise registration controllers to allow first and last name would require you to create your own controller under app/controllers/MODEL/registrations_controller.rb

Link to Devise controllers here

class MODEL::RegistrationsController < Devise::RegistrationsController
  before_filter :configure_permitted_parameters

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:first_name, :last_name])
  end
end

and instructing your routes.rb to use the controller

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

Replace MODEL with User like

rails generate devise User

It will generate User model under app/modeld/user.rb and user controller under app/controllers/users_controller.rb

run migration to add user table under database using command:

rake db:migrate
