Ruby Build a Simple Ruby on Rails Application Creating an Authentication System Updating the User Model

Now that attr_accessible is not valid, in Rails 4. How should we modify the code

I have modified the device user migration, added first_name, last_name and profile_name, modified the devise views, so that it will be able to accomodate the above fields. But I am unable to the attr_accessible, since it is not allowed, so first_name, last_name and profile_name are going to nil in the console. Any help will be greatly appreciated. Thanks

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
  # attr_accessible :title, :body

You wouldn't use attr_accessible or attr_ anything in Rails 4. But really, dude, your first port of call should be google. And there is plenty there is you just google "Rails 4 attr_accessible": https://www.google.es/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=rails%204%20attr_accessible

Anyway the thing is .. what I am asking is specific to devise. I know that rails 4 has params.permit thing. I figured out somehow .. you should override a method in controller .. `class ApplicationController < ActionController::Base before_filter :configure_permitted_parameters, if: :devise_controller?


def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_up) << :first_name << :last_name << :profile_name


Did it work? If so, good job!
