Models allows user to implement events when operation such as insert/update/delete is implemented to define business rules.
The following are the events supported by Phalcon\Mvc\Model:
| Operation | Name | Description |
|---|---|---|
| Inserting | afterCreate | It runs after the required operation over the database system only when an inserting operation is being made. |
| Updating | afterUpdate | It runs after the required operation over the database system only when an updating operation is being made. |
| Inserting/Updating | afterSave | It runs after the required operation over the database system. |
| Inserting/Updating | afterValidation | It is executed after the fields are validated for not nulls/empty strings or foreign keys. |
| Inserting | afterValidationOnCreate | It is executed after the fields are validated for not nulls/empty strings or foreign keys when an insertion operation is being made. |
| Updating | afterValidationOnUpdate | It is executed after the fields are validated for not nulls/empty strings or foreign keys when an updating operation is being made. |
| Inserting/Updating | beforeValidation | It is executed before the fields are validated for not nulls/empty strings or foreign keys. |
| Inserting | beforeCreate | It runs before the required operation over the database system only when an inserting operation is being made. |
| Inserting/Updating | beforeSave | It runs before the required operation over the database system. |
Implementation
<?php
namespace Phalcon\Tutorial;
use Phalcon\Mvc\Model;
class Tutorial extends Model
{
public function beforeValidationOnCreate()
{
echo 'This is executed before creating a class Tutorial!';
}
}
?>
