Devise and Strong Parameters

I would like to know how to integrate both of this gems(devise + Strong Parameters), since strong params will likely be added to the rails core in 4.0

any help is welcome


After adding both gems, devise will work as normal.

Update: With the latest version of Devise 3.x, as described at devise#strong-parameters, the authentication key (normally the email field), and the password fields are already permitted. However, if there are any additional fields on the signup form, you will need to let Devise know the extra fields to permit. The easiest way to do this is with a filter:

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


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

For Devise 2.x, if you use the safety feature requiring explicitly whitelisting tainted parameters in the user model:

include ActiveModel::ForbiddenAttributesProtection

the changes needed are found at which overrides some of the controllers.
