ruby on rails - Still getting "Current password can't be blank" in Registration Edit after following wiki -

i worry solution here woefully obvious, i'm having trouble implementing instructions on devise wiki (https://github.com/plataformatec/devise/wiki/how-to%3a-allow-users-to-edit-their-account-without-providing-a-password)

i'm using rails 4. after following wiki, i'm still receiving "current password can't blank". here's setup. assistance appreciated!

registrations_contoller.rb

class registrationscontroller < devise::registrationscontroller   def update     @user = user.find(current_user.id)      successfully_updated = if needs_password?(@user, params)       @user.update_with_password(devise_parameter_sanitizer.for(:account_update))       # rails 3:  @user.update_with_password(params[:user])     else       # remove virtual current_password attribute update_without_password       # doesn't know how ignore       params[:user].delete(:current_password)       @user.update_with_password(devise_parameter_sanitizer.for(:account_update))       # rails 3: @user.update_without_password(params[:user])     end      if successfully_updated       set_flash_message :notice, :updated       # sign in user bypassing validation in case password changed       sign_in @user, :bypass => true       redirect_to after_update_path_for(@user)     else       render "edit"     end   end    private   # check if need password update user data   # ie if password or email changed   # extend needed   def needs_password?(user, params)     user.email != params[:user][:email] ||       params[:user][:password].present?   end end 

application_controler.rb

class applicationcontroller < actioncontroller::base   protect_from_forgery with: :exception    before_filter :configure_permitted_parameters, if: :devise_controller?    def configure_permitted_parameters     devise_parameter_sanitizer.for(:account_update) |u|       u.permit(:first_name, :last_name, :username, :email, :avatar, :password, :password_confirmation)     end     devise_parameter_sanitizer.for(:sign_up) |u|       u.permit(:first_name, :last_name, :username, :email, :password, :password_confirmation)     end     devise_parameter_sanitizer.for(:sign_in) |u|       u.permit(:username, :email, :password)     end   end end 

routes.rb

projectfoo::application.routes.draw   devise_for :users, :controllers => { :registrations => "registrations",                                        :invitations => 'users/invitations' } 

note: i'm using devise_invitable gem

you have update_with_password twice. second time should update_without_password.
