Question

我必须测试我的应用程序，所以我想使用doctrine的fixture来在数据库中插入数据。我想创建一个实体的新条目（例如博客文章），它与用户实体（fosuser）有ManyToOne的关系。所以，我必须检索第一个用户设置为博客帖子作者。问题是当我运行命令时：

php app/console doctrine:fixtures:load

我收到以下错误：

Catchable fatal error: Argument 1 passed to BluEstuary\PostBundle\Model\Post::setOwner() 
must be an instance of BluEstuary\UserBundle\Model\User, null given, called in /Users/bface007/workspace/BluEstuary/esgis_gabon/src/ESGISGabon/PostBundle/DataFixtures/ORM/Posts.php on line 53 and defined in /Users/bface007/workspace/BluEstuary/esgis_gabon/src/BluEstuary/PostBundle/Model/Post.php on line 296`

我可以在非fixtures类中检索用户，但是当我尝试使用fixtures时它总是给出null值。有人可以帮帮我吗？

这是我的灯具类：

class Posts implements FixtureInterface, ContainerAwareInterface{
    public function load(Objectmanager $manager){
        $blogposts = array(
            array(
                "title" => "This is test 1",
                "content" => "I am a cool example"
            ),
            array(
                "title" => "This is test 2",
                "content" => "I am a cool example"
            )
        );

        $userManager = $this->container->get('fos_user.user_manager');
        $user = $userManager->findUserBy(array("id" => 3));

        foreach($posts as $i => $post){
            $new_posts[$i] = new BlogPost();
            $new_posts[$i]->setPostTitle($post["title"])
                        ->setPostContent($post["content"]);

            $new_posts[$i]->setAuthor($user);

            $manager->persist($new_posts[$i]);
        }

        $manager->flush();
    }
}

Answer 1

您想使用：

php app/console doctrine:fixtures:load --append

...所以它不会事先清空你的数据库

将正确的数据加载到夹具中的正确方法是使用参考。假设您有一个作者夹具：

AuthorFixture extends AbstractFixture implements OrderedFixtureInterface {
public function load(ObjectManager $om)
{
   $author = new Author("name", "surname"..);
   $this->setReference("author_1", $author);

   $om->persist($author);
   $om->flush();
}

/**
 * Get the order of this fixture
 * NOTE: the author comes before the Posts
 * @return integer
 */
public function getOrder()
{
    return 1;
}

}

然后在你的岗位上：

new_posts[$i] = new BlogPost();
new_posts[$i]->setAuthor($this->getReference("author_1");

..

/**
 * Get the order of this fixture
 * Note: the post comes after the author
 * @return integer
 */
public function getOrder()
{
    return 2;
}

在fixtures类中检索用户
