Question

我正在使用Symfony2，Doctrine2和MySql。我有两张桌子：评论和主题。 Review有一个复合PK（idReview和idHotel）。主题只有一个PK（idTopic）。我想在这两个表之间创建多对多关系。得到的连接表（例如Review_Topic）必须具有由三个FK组成的复合PK（idReview，idHotel，idTopic）。当我更新架构时，MySql给出了错误1005，无法创建表，错误150因为FK（idReview，idHotel）。遵循包含多对多关系的Review和Topic的Yaml配置：

Review:
...
    manyToMany:
        topics:
            targetEntity: Topic
            inversedBy: reviews
            joinTable:
                name: reviews_topics
                joinColumns:
                    idReview:
                        referencedColumnName: idReview
                    idHotel:
                        referencedColumnName: idHotel
                inverseJoinColumns:
                    topic_id:
                        referencedColumnName: idTopic
                fields:
                    score:
                        type: integer

Topic:
...
    manyToMany:
        reviews:
            targetEntity: Review
            mappedBy: topics

非常感谢您的帮助。
