Why model hooks may not work?

Hello!

Trying to use model hooks before/after create/update/save/delete and they're don't work. What i'm doing wrong?

This page (http://docs.phalconphp.com/en/latest/reference/models.html#events-and-events-manager) says, that everything i must to do is just add method to model with this name like onConstruct or initialize.

But when i create model, it not works.

BaseModel

<?php

namespace Api\Models;

use Phalcon\Mvc\Model;

class Base extends Model
{
    protected function getCache() { /* ... */}
    public function serialize() { /* ... */}

    public function validation() { /* ... */}

Cars

<?php

namespace Api\Models;

class Cars extends Base
{
    public $id;
    public $name;
    public $status; // NOT NULL in database

    const STATUS_DELETED = 0;
    const STATUS_ACTIVE  = 1;
    public static $statuses = array(
        self::STATUS_DELETED,
        self::STATUS_ACTIVE,

Somewhere in controller

<?php

namespace Api\Controllers;

class CarsController extends RestController
{
    public function createOne()
    {
        $whiteList = array(
            'name',
        );

        $car = new Cars();

        // OK it's empty
        var_export($car->toArray()); // array ( 'id' => NULL, 'name' => NULL, 'status' => NULL, )

        // Let's create new!
        $created = $car->create($this->request->getPost(), $whiteList);

        // Why status is NULL? beforeSave does not working?
        var_export($car->toArray()); // array ( 'id' => NULL, 'name' => 'foo', 'status' => NULL, )

        // $created == false
        if ($created) $this->respond($car->toArray());

        // Here i've got error:"status is required"
        $this->error($car->getErrorMessages());
    }
}

?>

Thanks for the reply!

I've right now tried adding status, fill whitelist from Cars::columnMap() and even use Model::create() without any whitelist.. but no, var_export($car->toArray()) after create is the same in all these tests and i've got same error.

In post data i have in this case simple array: array ('name' => 'foobar')

$whiteList = array( 'name', );

because whitelist doesnt include status maybe? whitelist is used to verify which fields can be altered.

found your answer..

beforeValidationOnCreate

beforeValidationOnCreate Is executed before the fields are validated for not nulls/empty strings or foreign keys when an insertion operation is being made

Hell yeah, "beforeValidationOnCreate" did the trick!

I didn't know that validation on database layer is validation even on application too (Phalcon in this case) layer (o.0) Strange behaviour.

Thank you!
