我有一个User实体，在多对多关系数据库中附加了商店。 我用我的控制器加载商店：
$userrepository = $this->getEntityManager()->getRepository('Thuiswinkelen\Entity\User');
$user = $userrepository->findOneBy(array('id' => $this->getUserId()));
$stores = $user->getStores();
这很好用。
现在，我希望登录用户选择附加到他的商店，并向他展示该商店中的所有商品。
我想到这样的事情：
$user->getStore($storeid)->getProducts();
这不起作用，因为我没有像这样设置实体。 我也认为这是一种不好的做法（？）
第二个选项是
$storerepository = $this->getEntityManager()->getRepository('Thuiswinkelen\Entity\Store');
$store = $storerepository->findOneBy(array('id' => $storeid));
但在这种情况下，每个人都可以查看未附加到商店的商品。
怎么做？
我的实体看起来像这样：

答案 0 :(得分：2)
我认为，你的第二种方法是更好的方法。您应该使用存储库，甚至更好的服务类（内部处理存储库）来访问您的用户，商店等。在这种情况下，将分别为用户和商店提供两个单独的服务。然后，你打电话：
$user = $userService->get($userId);
获取用户，并且：
$store = $storeService->get($storeId);
获取您想要的商店。
对于访问控制，您可以在任一服务中简单地实现类似hasStore(User $user, Store $store)方法的内容，并在需要时调用它。
当然，有一个很大的问题是，是否首先在您的应用程序中引入服务层，但通常它被认为是一种良好的做法（在大多数情况下）。
答案 1 :(得分：0)
在您的情况下，请尝试
$userrepository = $this->getEntityManager()->getRepository('Thuiswinkelen\Entity\User');
$user = $userrepository->findOneBy(array('id' => $this->getUserId()));
$stores = $user->getStores();
$product = array();
foreach ($stores as $store) {
$product[] = $store->getProducts();
}
但是，我认为这是一个坏主意：
/** * @var \Doctrine\Common\Collections\Collection * @ORM\ManyToMany(targetEntity="Application\Entity\Product" ) * @ORM\JoinTable(name="product_store", * joinColumns={@ORM\JoinColumn(name="product_id", referencedColumnName="id")}, * inverseJoinColumns={@ORM\JoinColumn(name="store_id", referencedColumnName="id")} * ) */ protected $products;
我的想法 - 你需要另一张带有约束的表idStore＆lt; - ＆gt; idProduct
