Override devise registrations controller

Question

I have added a field to the sign-up form that is based on a different model, see How do I use nested attributes with the devise model for the gory details. This part is work

Answer 1

Very simple methods Just go to the terminal and the type following

rails g devise:controllers users //This will create devise controllers in controllers/users folder

Next to use custom views

rails g devise:views users //This will create devise views in views/users folder

now in your route.rb file

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

You can add other controllers too. This will make devise to use controllers in users folder and views in users folder.

Now you can customize your views as your desire and add your logic to controllers in controllers/users folder. Enjoy !
