學說：沒有指定的標識符/主鍵

Question

所以我的一切設置，但我仍然得到：

沒有標識/主要用於實體 指定鍵「Bisna \應用\實體\公司」。每個實體必須有一個 標識符/主鍵。

實體：

<?php 
namespace Bisna\Application\Entity;

我還沒有做出的表呢，不過，我仍然不明白爲什麼我得到這個錯誤，因爲我所擁有的一切。有任何想法嗎？

Answer 1

也許是因爲你錯過了@之前@ORM\Column註釋爲$id屬性？

你應該考慮使用Yaml原則映射。這是將實體與數據庫列定義分開的好方法。此外，您的IDE應該驗證Yaml內容，但它可能不會驗證PHP註釋爲PHP代碼。
