我一直在努力解決這個問題，但沒有運氣。學說一對多/多對一。不工作
一是一些澄清：
基本上我要創建「用戶」和「存儲」，我的計劃，以確定您的收藏夾商店特定的用戶，並且還從存儲的角度看，誰在一個商店之間的關係特別的商店作爲他們喜歡的商店 我的猜測是使用ManyToMany關係，但在查找關於此的示例後，許多網站描述如果您需要與其他字段的ManyToMany關係（在我的情況下，我有3個額外的字段），您必須使用OneToMany/ManyToOne而不是
我使用SQLite我DB只是爲了發展，我寫的用超薄框架得到使用這樣的特定的實體時
一切正常，在PHP REST API。
/**
* Fetching user by email
* @param String $email User email
*/
public function getUserByEmail($email) {
$user = $this->getEntityManager()->getRepository('User')
->findOneBy(array('email' => $email));
if ($user === null) {
return null;
} else {
return $user;
}
}
或
$ProductStore = $this->getEntityManager()->getRepository('ProductStore')
->findOneBy(array('product' => $product,
'store' => $store));
或
$Store = $this->getEntityManager()->getRepository('Store')
->findOneBy(array('state' => $State->getId(),
'city' => $City->getId(),
'streetname' => $streetname,
'streetnumber' => $streetnumber));
//Store has many ManyToOne relations to other Entities
//like State or City, but all of them works as expected
一旦我得到我能讀懂他們的屬性的任何實體。除了當我嘗試獲取：
echo $User->getShopsAt(); i get an error saying "Object of class Doctrine\ORM\PersistentCollection could not be converted to string"
，如果我嘗試
echo [$User->getShopsAt()]; i get "Array" as reponse
，如果我嘗試
echo count([$User->getShopsAt()]); i get 1
如果我理解調用getShopsAt（）應返回的所有實例「UserStore」實體匹配用戶ID，但我無法訪問其任何屬性。 我試過的一切都失敗了，另外我想指出的是，我使用了UserStore表中有兩個條目的用戶ID「1」。那麼爲什麼計數返回1.
我已經創建了使用YML格式的3架構，因爲我覺得它比PHP更清晰。
有了這些模式我創建使用命令我的實體「供應商/斌/學說的ORM：生成實體./src」 （見底部產生的實體）
然後，我創建數據庫模式使用供應商/斌/學說ORM：架構工具：更新--force （參見SQL數據庫，並在底部數據）
這個我已經創建了使用Advaced REST客戶端擴展數據庫中的某些數據後在Chrome瀏覽器上。但我已經創建了所有他們獨立。這意味着，首先不上shopsAt屬性進行任何設置創建用戶，然後創建了一些房屋沒有設置任何的購物者屬性，然後創建了一些UserStores
重要的問題： 在創建UserStore的，我必須恢復實際的用戶和存儲以設置關係的反轉側？
或
不只是增加正確的鑰匙，UserStore和學說用戶/存儲的讀取期間將做比賽，因爲UserStore的創建是不夠，因爲，因爲它是關係的擁有方？
或
我必須手動修改由ORM產生的實體自動：生成實體命令和在所述方法中setStore和UserStore的SETUSER更新倒轉側？如前所述Here
我的數據庫看起來是這樣的：

用於調試的快速提示：嘗試'dump（$ value）;'而不是'echo $ value'。 –
謝謝托馬斯。您的評論是有用的，轉儲沒有工作，但我按照你的想法，並發現在PHP文檔var_dump。在使用它之後，它顯示了一個幾乎不可能理解的巨大結構，但是我能夠看到關係中使用的所有字段，並且發現了錯誤。在我的用戶YML文件被設置爲mappedBy：產品，應該是mappedBy：用戶。再一次，謝謝 – Gatunox
哦，對不起，它是'var_dump（$ value）;'當然。 * dump *是我使用的調試工具的自定義函數。無論如何，我很高興它幫助你。 –
