我试图建立一个一对多的关系，如下所示

我有一个UserProfile实体，它有一些私有字段，它有两个字段是另一个实体：

音乐品味：身份证和姓名
收藏夹艺术家：Id和姓名

起初，我只做了一个onetoMany关系，因为我希望一个用户配置文件有一系列的音乐品味和另一系列的艺术家

这些就是我现在拥有的实体：

用户配置文件：

当我更新条令模式时，一切看起来都很好，但如果我这样做：

我必须在音乐品味和喜爱的艺术家之间建立一种多人的关系？（之前我做过，但没有创建任何关系…）但验证时有一些失败：

$php bin/控制台原则：模式：验证

[Mapping]  FAIL - The entity-class 'myDomain\Entity\FavouriteArtist' mapping is invalid:
* The mappings myDomain\Entity\FavouriteArtist#userProfile and myDomain\Entity\UserProfile#favouriteArtist are inconsistent with each other.

[Mapping]  FAIL - The entity-class 'myDomain\Entity\MusicalTaste' mapping is invalid:
* The mappings myDomain\Entity\MusicalTaste#userProfile and myDomain\Entity\UserProfile#musicalTaste are inconsistent with each other.

[Mapping]  FAIL - The entity-class 'myDomain\Entity\UserProfile' mapping is invalid:
* The association myDomain\Entity\UserProfile#musicalTaste refers to the owning side field myDomain\Entity\MusicalTaste#musicalTaste which does not exist.
* The association myDomain\Entity\UserProfile#favouriteArtist refers to the owning side field myDomain\Entity\FavouriteArtist#favouriteArtist which does not exist

我怎样才能修好它们？提前感谢

正如梅米特所说：

将userProfile.yml中的“mappedBy:musicalTaste”更改为“mappedBy:userProfile”效果很好。

您可以尝试将userProfile中的“mappedBy:musicalTaste”更改为“mappedBy:userProfile”。yml在验证时通过userProfile更改它们解决了问题，但为什么？musicalTaste是userProfile实体的一个字段。。。无论如何谢谢你！我不知道太多细节。我认为这是教义的YML语法，当它想使用双向方式的桥梁时。你可以阅读条令网站了解详情。
