I want to set devise_parameter_sanitizer individually when I create two devises

Create two devises and write the procedure when you want to set individual devise_parameter_sanitizer.

The original application is being created.

ruby '2.6.5' rails　'6.0.0'

First, as a prerequisite, start with each devise's routing, model, controller, and view settings. Please refer to here for the above creation method.

Now, normally, if there is one devise for one application, use before_action in the application_controller.rb file to process devise_parameter_sanitizer.

app/controllers/application_controller.rb

   class ApplicationController < ActionController::Base
  before_action :configure_permitted_parameters, if: :devise_controller?

  private
  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:nickname])
  end
end

In this way, you can allow a specific column when registering as a user.

This is how to set devise_parameter_sanitizer of different models when two devises are created.

This time I made two devises, user and doctor.

First of all, it's in the README of the repository, so I tried it, but it didn't work. I didn't know whether to create a file to inherit or to utilize an existing file.

As a result, there is an individual file app / controllers / users / registrations_controller.rb, so use that.

For User
    app/controllers/users/registrations_controller.rb

For Doctor
    app/controllers/doctors/registrations_controller.rb

Find the following description in the large number of commented outs in the user file.

app/controllers/users/registrations_controller.rb

   #  before_action :configure_sign_up_params, only: [:create]

Enable comments for. . ↓

app/controllers/users/registrations_controller.rb

   before_action :configure_sign_up_params, only: [:create]

Now, when creating a user, Now that configure_sign_up_params is called In the same file, def configure_sign_up_params Comment out and enable it.

app/controllers/users/registrations_controller.rb

   def configure_sign_up_params
     devise_parameter_sanitizer.permit(:sign_up, keys: [:nickname])
   end

Then write the karamu you want to add to this (: sign_up, keys: [: nickname]) part.

app/controllers/users/registrations_controller.rb

 def configure_sign_up_params
    devise_parameter_sanitizer.permit(:sign_up, keys: [:nickname, :password])
  end

Doctor will do the same work. The file is app / controllers / doctors / registrations_controller.rb.

As some of you may have noticed, devise_parameter_sanitize is not written in app / controllers / application_controller.rb because it is not defined in the application controller and is called by before_action in an individual file.

When doing the above

　　　TypeError

　　　superclass mismatch for class DoctorController

   class DoctorController < ApplicationController

I got an error. If you look closely, class DoctorController <ApplicationController is Doctor.

   class DoctorController < ApplicationController

   class DoctorsController < ApplicationController

Since it inherits from app / controllers / doctors / registrations_controller.rb, there is no "" s "", so describe it.

Rails has strict naming conventions, so be careful! !!
