保持FOSUser实体级联的好办法

问题描述

我想要保留一个用户实体扩展FOSUserBundle实体，但发生错误：

I want to persist a User entity extends FOSUserBundle entity but an error occured :

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'username_canonical' cannot be null

如何重载我的用户实体的持久化功能给出需要的信息？

How can I overload the persist function of my User entity to give the informations it needs ?

我的用户实体：

class User extends BaseUser
{
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
     protected $id;

     /**
      *
      * @ORM\OneToOne(targetEntity="MyApp\MainBundle\Entity\Project")
      */
     private $project;
...
}

我的项目实体：

class Structure
{
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var integer $master
     *
     * @ORM\OneToOne(targetEntity="Uriae\UserBundle\Entity\User", cascade={"persist"})
     *
     * @Assert\NotBlank()
     * @Assert\Type(type="Uriae\UserBundle\Entity\User")
     */
    private $master;
...
}

编辑回复FractalizeR：

EDIT TO RESPONSE FractalizeR :

你的意思是我必须手动设置usernameCanonical属性后坚持吗？

Do you mean i must set manually the usernameCanonical property after the persist ?

积极地在表单发送后我的控制器：

Actyally i have that after the form is sent in my controller :

$structure = new \Uriae\MainBundle\Entity\Structure();
if ($request->getMethod() == 'POST')
{
    $form->bindRequest($request);

    if ($form->isValid())
    {
       $em = $this->getDoctrine()->getEntityManager();
       $em->persist($structure);
       $em->flush();

       ...
    }
}

你的意思是我必须手动设置usernameCanonical属性后坚持吗？或何时/何时？但是特别是如何？

Do you mean I have to set manually the usernameCanonical property after the persist ? Or where/when ? But especially how ?

推荐答案

创建结构然后尝试持续/冲洗... Doctrine2是：

When you're creating an instance of Structure and then trying to persist/flush... Doctrine2 is:

1. 意识到结构之间存在关系与用户（每个结构实例必须有一个 / code>实例）


2. 因为没有用户明确绑定到 code>实例，它尝试创建一个空的。


3. User 上的保存操作失败，因为有没有数据（在这种情况下，usernameCanonical字符串为空）

1. Realising that there is a relationship on Structure with User (each Stucture instance must have a User instance)
2. Because there is no User explicitly bound to the Structure instance, it tries to create an empty one.
3. The save operation on the User fails, because there is no data (in this case, usernameCanonical string is empty)

您必须做的是...

在保存结构之前，添加一个用户的实例...如果您要使用当前用户，则使用此

Before you save the Structure, add an instance of User to it... if you want to use the current user then use this

$user = $this->get('security.context')->getToken()->getUser();
$structure->setMaster($user);
$em->persist($structure);
$em->flush();

请记住，将用户实体包含在您的控制器类（使用使用语句）。

Remember to include the User entity in your controller class (with the use statement).
