Symfony2 / доктрина вставка с внешними ключами

В symfony2, когда я вставляю данные в базу данных, я получаю исключение:


     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"]:

        $product->setTopic($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());

Пожалуйста, помогите, потому что я застрял с ним :)

Прежде всего, кажется, вы неправильно поняли отношения в доктрине2.

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;
}

Ваш @ORM\Column бесполезен, так как ORM\JoinColumn делает это (более или менее и, вероятно, лучше). Кроме того, ваш атрибут $ topic_id следует называть $ topic, так как вы будете работать только с объектами ForumTopics.

Вот хороший способ справиться с отношениями (позволяя иметь отношение NULL и исправлять вашу ошибку sql):

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