JDL：UndeclaredEntityException

Question

我正在使用jdl对我的数据库进行原型设计，我很喜欢它的简单性。问题是文档有点轻，我收到这个错误： UndeclaredEntityException: In the relationship between Room and Pictures, Pictures is not declared.

以下是代码：

...

entity Room {
    RoomId Integer required,
    RoomName String,
    SquareFootage Integer,
    HasRefrigirator Boolean,
    PrivateBathroom Boolean
}

entity Picture {
    Picture Integer required,
    Url String
}
...

relationship OneToMany {
    Room to Pictures{RoomId},
    ....
}

我不确定这意味着什么。

Answer 1

这是问题所在。

relationship OneToMany {
    Room to Pictures{RoomId},
    ....
}

将Pictures更改为Picture
