Phalcon在模型中初始化函数

Question

I have 3 models, Where

Basemodel
Model_A
Model_B

In Basemodel i have initialize function setting a property value

In Model_A i don't have initialize function, if i return anything from model 
it will be successful

In Model_B i have initialize function, if i return anything from this model 
its not returning anything. No Error, Nothing, Just Blank.

Base Models With initialize()

class Basemodel extends \Phalcon\Mvc\Model {

    protected $name;

    function initialize() {
        $this->name = 'MyApplication';
    }

}

Model A Without initialize():

class Model_a extends Basemodel {
    function test() {
        return $this->name; // WORKING
    }
}

Model B With initialize():

class Model_b extends Basemodel {
    public $b;
    function initialize() {
        $this->b = 'someName';
    }

    function rawtext() {
        return $this->name;  // NOT WORKING
    }
}

If remove initialize() from Model_B, Then its returning the value successfully

Answer 1

This happens because in child classes you are overriding BaseModel initialize method.

If you want to extend initilize in child class you should call initialize from parent class - here BaseModel.

Model A/B should be:

class Model_b extends Basemodel {
    public $b;
    function initialize() {
        parent::initialize(); // Call parent's class initialize
        $this->b = 'someName';
    }

    function rawtext() {
        return $this->name;  // SHOULD WORK
    }
}
