Question

Could someone tell me how to add the default value on a DateTime column? I can’t do it like this:

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

So how can I handle it?

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.
