夹具 DOCTRINE2

Fixture DOCTRINE2

当我使用时:

php app/console doctrine:fixtures:load --fixtures=/var/www/Symfony/src/BISSAP/ForumBundle/DataFixtures/ORM**

我收到以下错误:

PHP Catchable fatal error: Argument 1 passed to BISSAP\ForumBundle\Entity\Forum::setCategory() must be an instance of BISSAP\ForumBundle\Entity\Category, null given, called in /var/www/Symfony/src/BISSAP/ForumBundle/DataFixtures/ORM/LoadForum.php on line 40 and defined in /var/www/Symfony/src/BISSAP/ForumBundle/Entity/Forum.php on line 184

我的夹具 - LoadForum.php:

<?php
namespace BISSAP\ForumBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use BISSAP\ForumBundle\Entity\Forum;
use BISSAP\ForumBundle\Entity\Category;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class LoadForum extends Controller implements FixtureInterface
{

 public function load(ObjectManager $manager)
 {
    $data=array(array('NAME','DESCRTIPTION','60',$manager->getRepository('BISSAPForumBundle:Category')->find('1')),
                array('NAME2','DESCRTIPTION2','60',$manager->getRepository('BISSAPForumBundle:Category')->find('2')));

    foreach ($data as $for) {
      $forum = new Forum();
      $forum->setName($for[0]);
      $forum->setDescription($for[1]);
      $forum->setOrdre($for[2]);
      $forum->setCategory($for[3]);

      $manager->persist($forum);
      }

    $manager->flush();
  }
}

doctrine:fixtures:load 擦除数据库中的所有数据并加载新的 fixtures

我相信你的问题是

$manager->getRepository('BISSAPForumBundle:Category')->find('1')

return 空结果而不是类别对象

看起来您要么在类别之前加载了论坛固定装置,要么您没有考虑到数据库已被删除并且您没有类别的任何记录。

对于情况 1,您应该更改灯具加载顺序 - 更改类别灯具的功能 "getOrder" 并设置 returned 编号低于论坛

上的编号

对于情况 2,您还应该为某些类别创建灯具

顺便说一句,你应该使用对象的引用,而不是从存储库中获取,所以常见的方法是:

  1. 为类别夹具创建新参考

    $类别=新\MyApp\CategoryBundle\Entity\Category();

    $category->setName();

    $this->addReference('MyApp\CategoryBundle\Entity\Category-1',$category);

  2. 调用创建的引用以填充论坛

    $forum->setCategory($this->getReference('MyApp\CategoryBundle\Entity\Category-1'));
