Adding custom parameters to devise registration - unpermitted parameters

Question

I\'ve been trying to customize the devise register method to register with more parameters and also update more(no luck so far), but I always get Unpermitted parameter

Answer 1

The accepted answer says the config should go in your applicationController but it can simply go in your user registration controller and you can specify that you only want to run it for create method and nothing else:

class Users::RegistrationsController < Devise::RegistrationsController
  before_action :configure_sign_up_params, only: [:create]

  protected

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