Symfony2多对一获取空参数

Question

I have a many-to-one relationship with the 'login_log' and 'user_info' and 'user_account'. this is three entity's summary.

class UserInfo extends Entity {

    /**
     * @ORM\Column(name="user_id", type="integer")
     * @ORM\Id
     */
    protected $userId;

    /**
     * @ORM\Column(name="true_name", type="string", length=20)
     */
    protected $trueName;

    ...
}



class UserAccount extends Entity {

    /**
     * @ORM\Column(name="user_id", type="integer")
     * @ORM\Id
     */
    protected $userId;

    /**
     * @ORM\Column(name="user_name", type="string", length=20, nullable=true)
     */
    protected $userName;

    ...
}




class LoginLog extends Entity {

    /**
     * @ORM\Column(name="log_id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $logId;

    /**
     * @ORM\ManyToOne(targetEntity="UserInfo")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="user_id")
     */
    protected $userInfo;

    /**
     * @ORM\ManyToOne(targetEntity="UserAccount")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="user_id")
     */
    protected $userAccount;

    /**
     * @ORM\Column(name="user_id", type="integer")
     */
    protected $userId;

    ...
}

when i want add login log:

$log = new LoginLog();
$log->setUserId(11);
$em->persist($log);
$em->flush();

but in symfony profiler, i got those query:

INSERT INTO login_log (user_id) VALUES(?) 
Parameters: { 1: null}  

why first parameters is null!

Answer 1

this makes no sence :

    /**
     * @ORM\ManyToOne(targetEntity="UserAccount")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="user_id")
     */
    protected $userAccount;

    /**
     * @ORM\Column(name="user_id", type="integer")
     */
    protected $userId;

they are both using the same columnname, get rid of the userId property, and use a setter for userAccount.

Right now, you are setting one thing, and when makeing the query, doctrine freaks out, and uses the other one.

Understand what i mean ?

$log = new LoginLog();
$log->setUserAccount($user);  // $user beeing an actual user, not an ID
$em->persist($log);
$em->flush();
