grails - Grails:按详细信息域字段控制主域字段[hasMany]

Question

有域:

class Order {
  static hasMany = [execDepartments: Department]
  String orderNo
  //boolean signature 
  ...
}

class Department {
  String name
  ...
}

我想为Order添加 bool(boolean) 签名字段，但是要按部门添加，因此我需要为execDepartments添加字段签名。可能吗？请帮忙。

Answer 1

这是m:m关系吗？

为什么不创建另一个域，如

class Order {
  static hasMany = [execDepartments: DepartmentOrder]
  String orderNo
  //boolean signature 
  ...
}

class DepartmentOrder{
    boolean signature
    Order order
    Department department
}

class Department {
    String name
    static hasMany = [execOrders: DepartmentOrder]
}

然后你可以写belongeTo
