Devise 3 (rails 4) can't update user without password

Question

I\'m trying to update a user without having to provide a password, but approaches that worked on older devise/rails versions no longer work with devise 3 and rails 4 strong para

Answer 1

simply override the Devise by creating app/controller/registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController

  protected
  def update_resource(resource, params)
    resource.update(params.except(:current_password))
  end
end

this code will directly update user params except :current_password

and update config/routes.rb

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