Yes.I read that, but i am a little confused about 'modelsCache' service. Once you setup that service, how do i destroy cache when i update or delete models.Use events like beforeSave? And i want use \Phalcon\Cache\Backend\File CLASS in the Model's STATIC function find and findFirst, how do i setup that. @Karol Marcinkiewicz you're a kind person, thanks a lot. These questions are too naive, THANKS you again for your patient.
