Symfony2的關係不是在子類中正確映射

Question

這裏是我的問題：

我有一個類物種女巫是抽象的，我有一個擴展的物種另一個階級「RAIE」。 我與物種之間有一種關係ManyToOne物種，因爲每個物種都有一種類型。

當我使用原則來生成數據庫時，它會生成一個表格種類（因爲它是抽象的）和表格Raie。

爲了避免生成物種表，我應該從實體定義中刪除@ORM\Table()嗎？它夠了嗎？

的主要問題是表RAIE有物種定義的每個屬性exept關係到typeSpecies實體！

這裏是我的兩個類的定義，以幫助您瞭解：

您可能需要更改繼承類型的抽象類。閱讀更多關於Doctrine 2和繼承映射的Doctrine documentation
