Doctrine 2.1 - datetime column default value

Question

Could someone tell me how to add default value on datetime column? I can\'t do this like this:

protected $registration_date = date(\"Y-m-d H:i:s\", time());
         


        

Answer 1

You map your property as DateTime type then set the value in the constructor using a new DateTime instance:

/**
 * @Entity
 * @Table(name="...")
 */
class MyEntity
{
    /** @Column(type="datetime") */
    protected $registration_date;

    public function __construct()
    {
        $this->registration_date = new DateTime(); 
    }
}

This works as the constructor of a persisted class is not called upon hydration.
