Adding extra registration fields with Devise

Question

I am trying to add some extra fields to registrations#new. Since I only want extra data and do not need different functionality, I don\'t see why I need to override controll

Answer 1

I've had similar situation (just fields were different).

Here's the way official documentation can offer: Just add this to your ApplicationController. And change "username" to whatever you need, and add some more if you need.

before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) << :username
  end

My Applications Controller looks like that:

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

    def configure_permitted_parameters
      devise_parameter_sanitizer.for(:sign_up) << :public_name
    end
end

Answer 2

OK, so what I did was just override the Devise registration controller, update routes.rb as per the devise docs to reflect this, copied and pasted the Devise code for registrations#create as is, and change the getting params part to use my own strong parameters method, and that was that.

class RegistrationsController < Devise::RegistrationsController

  def create
    build_resource(registration_params)

    if resource.save
      if resource.active_for_authentication?
        set_flash_message :notice, :signed_up if is_navigational_format?
        sign_up(resource_name, resource)
        respond_with resource, :location => after_sign_up_path_for(resource)
      else
        set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
        respond_with resource, :location => after_sign_up_path_for(resource)
      end
    else
      clean_up_passwords
      respond_with resource
    end
  end  

  private

  def registration_params
    params.require(:user).permit(:email, :title_id, :first_name, :last_name, 
      :province_id, :password, :password_confirmation)
  end

end
