ruby on rails - 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 parameters: error. I tried using this Adding extra registration fields with Devise and https://github.com/plataformatec/devise#strong-parameters, but I cant get over that.

I've also thought about creating a new table to hold a foreign key the user id and put in there stuff like user_id, display_name, profile_picture, but I would have the same problem when trying to submit everything from the same page(mess with the devise controller).

Do you have any suggestions on how I can solve this? What else do I have to post?

routes.rb

devise_for :users, controllers: { registrations: 'users/registrations' }

users/regC

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_paramss
    params.require(:user).permit(:email, :display_name, :terms_of_services, :profile, :password, :password_confirmation)
  end

Looks like you just need to tell devise which parameters should be permitted. By default, devise permits the email (or username depending on configuration), password and password_confirmation params. You just need to add more.

The devise documentation suggests a "lazy way" of setting this up.

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

  protected

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

The documentation then says that

If you have nested attributes (say you're using accepts_nested_attributes_for), then you will need to tell devise about those nestings and types.

Only if you need to override the registrations#create action you should provide your custom route for devise. In that case, make sure you override the sign_up_params method too.

class Users::RegistrationsController < Devise::RegistrationsController
  def create
    # Your custom code here. Make sure you copy devise's functionality
  end

  private

  # Notice the name of the method
  def sign_up_params
    params.require(:user).permit(:display_name, :email, :password, :password_confirmation)
  end
end

In essence, you'd have to look into how your sign up form is posting the parameters to figure out how to configure strong parameters in the controller. Make sure you read on strong parameters syntax as well.

Hope it helps!
