Strong parameters with Rails and Devise

Question

I am using the rails 4.0 branch of devise along with ruby 2.0.0p0 and Rails 4.0.0.beta1.

This is the kind of question where I am checking if I\'m doing it the right

Answer 1

It works very nice with adding an module in config/initializers with all parameters like this

module DevisePermittedParameters
  extend ActiveSupport::Concern

  included do
    before_filter :configure_permitted_parameters
  end

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :email, :password, :password_confirmation) }
  end

end

DeviseController.send :include, DevisePermittedParameters

Answer 2

Thanks for the latest updates on Rails4 branch of Devise, it doesn't really need to insert 'resource_params'.

I've created a brand new Rails4 app and followed basic Devise installation steps and my app works properly, so I think, you've done well.

But there is a modified gist which gives you some extra details in terms of permitted parameters if you need:

Source: https://gist.github.com/bluemont/e304e65e7e15d77d3cb9

# controllers/users/registrations_controller.rb
class Users::RegistrationsController < Devise::RegistrationsController

  before_filter :configure_permitted_parameters

  protected

  # my custom fields are :name, :heard_how
  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:name, :heard_how,
        :email, :password, :password_confirmation)
    end
    devise_parameter_sanitizer.for(:account_update) do |u|
      u.permit(:name,
        :email, :password, :password_confirmation, :current_password)
    end
  end
end

Answer 3

For Rails 5, Devise 4 Use this:

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

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:first_name, :last_name, :email, :password, :password_confirmation])
  end
end
