Symfony 2學說一對多關係映射難倒

Question

我收到一個錯誤'Error：調用未定義的方法Login \ LogBundle \ Entity \ User :: getToken（）' 當試圖從另一個實體apiuserdetails。 user_id是apiuserdetails中的外鍵。我一直在關注示例http://symfony.com/doc/current/book/doctrine.html關係映射模型。我能夠使用getRepository（「LoginLogBundle：UserApiProfile」）從用戶實體獲取信息，但是如果按照他們描述的方式進行反向操作，則會出現錯誤。我在做映射時遇到了問題，但看不到它。會感謝一些幫助，謝謝。

Answer 1

如果你得到\Login\LogBundle\Entity\User你沒有setToken並在錯誤信息中說明。因爲你沒有導航屬性到\Login\LogBundle\Entity\UserApiDetails，事實上，如果你朝着這個方向前進，你會陷入困境。您可以從User獲取導航屬性，以獲取（單個或列表）UserApiDetails，或者獲取UserApiDetails並使用導航屬性獲取User信息。在後一種情況下，你可以在樹枝簡單地使用{{ userapi.user.token }}
