Doctrine 2.1 - error in DateTimeType

Question

I'm trying to add user to my database through Doctrine 2.1 project and I'm getting that kind of error:

Fatal error: Call to a member function format() on a non-object in C:...\Doctrine\DBAL\Types\DateTimeType.php on line 44

Database table itself created with no problems. What could be wrong with my following code?

<?php
/**
 * @Entity @Table(name="users")
 */
class User {
    /**
     * @Id @GeneratedValue @Column(type="integer")
     * @var string
     */
    protected $id;

    /**
     * @Column(type="string", length=20, unique=TRUE)
     * @var string
     */
    protected $login;

    /**
     * @Column(type="string", length=50, nullable=TRUE)
     * @var string
     */
    protected $nickname;

    /**
     * @Column(type="string", length=50, nullable=TRUE)
     * @var string
     */
    protected $firstname;

    /**

     * @var string
     */
    protected $lastname;

     */
    protected $newsletter = FALSE;

    public function __construct() {
        $this->registration_date = date("Y-m-d H:i:s");
    }

    public function getId() { return $this->id; }

    public function getLogin() { return $this->login; }

    public function boostCommentsAmount() { $this->comments_amount++; }

    public function getNewsletter() { return $this->newsletter; }
    public function setNewsletter($newsletter) { $this->newsletter = $newsletter; }
}

Thanks for help in advance.

Answer 1

Doctrine requires date(time) columns to contain DateTimeobjects. So in fact your constructor should read

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

Answer 2

I'm sure it's something with the __construct()
