phalcon:model 事件与事件管理器

事件与事件管理器（Events and Events Manager）¶

Models allow you to implement events that will be thrown when performing an insert/update/delete. They help define business rules for a certain model. The following are the events supported by Phalcon\Mvc\Model and their order of execution:

Inserting/Updating	beforeValidation	YES	Is executed before the fields are validated for not nulls/empty strings or foreign keys
Inserting	beforeValidationOnCreate	YES	Is executed before the fields are validated for not nulls/empty strings or foreign keys when an insertion operation is being made
Updating	beforeValidationOnUpdate	YES	Is executed before the fields are validated for not nulls/empty strings or foreign keys when an updating operation is being made
Inserting/Updating	onValidationFails	YES (already stopped)	Is executed after an integrity validator fails
