在symfony2中，当我将数据插入数据库时​​，我收到一个异常：


     An exception occurred while executing 'INSERT INTO forum_posts (topic_id, user_id, is_first, post, cdate) VALUES (?, ?, ?, ?, ?)' with params [null, null, "0", "lorem ipsum dooorrrrllosdosodsdd", "2015-02-17 11:35:22"]:

当我尝试从ForumPostController插入数据库时​​

代码：



$em = $this->getDoctrine()->getManager();

        $cur_date = date_create(date('Y-m-d H:i:s'));

        $product = new ForumPosts();

        $product->setTopic($em->getRepository('TestTestBundle:ForumTopics')->findOneById($request->request->get('topicId'));
        $product->setUser($em->getRepository('TestTestBundle:User')->findOneById($request->request->get('userId')));

        $product->setIsFirst($request->request->get('isFirst'));

        $product->setPost($request->request->get('post'));
        $product->setCdate($cur_date);
        $em = $this->getDoctrine()->getManager();

        $em->persist($product);
        $em->flush();

        return new Response('Created record id '.$product->getId());

请帮助，因为我坚持了下来：）

1 个答案:

答案 0 :(得分：0)

首先，似乎你在学说2中误解了关系。

class ForumPosts
{
    // ...
    /**
     * @ORM\ManyToOne(targetEntity="ForumTopics", inversedBy="forum_posts")
     * @ORM\JoinColumn(name="topic_id", referencedColumnName="id")
     */
    private $topic_id;
    protected $topic;
    private $posts;

    // ...

    /**
     * @var integer
     *
     * @ORM\Column(name="topic_id", type="integer", type="decimal", options={"default"="0"})
     */
    private $topicId;
}

你的@ORM \ Column是没用的，因为ORM \ JoinColumn这样做（或多或少，可能更好）。此外，您的属性$ topic_id应该被称为$ topic，因为您只能使用ForumTopics对象。

这是处理关系的好方法（允许有一个可以为空的关系，并修复你的sql错误）：

class ForumPosts
{
    // ...
    /**
     * @ORM\ManyToOne(targetEntity="ForumTopics", inversedBy="forum_posts")
     * @ORM\JoinColumn(name="topic_id", referencedColumnName="id", nullable=true)
     */
    private $topic;
}
