def try_spree_current_user
  respond_to?(:spree_current_user) ? spree_current_user : nil
end

#unauthorized ⇒ Object

Redirect as appropriate when an access request fails. The default action is to redirect to the login screen. Override this method in your controllers if you want to have special behavior in case the user is not authorized to access the requested action. For example, a popup window might simply close itself.
