Grails：主域字段按详细域字段 [hasMany]

发布于 2024-12-12 07:45:10 字数 260 浏览 0 评论 0原文

有域：

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

class Department {
  String name
  ...
}

我想为订单添加布尔签名字段，但按部门添加，因此我需要 execDepartments 为订单添加字段签名。是否可以？请帮忙。

原文

There are domains:

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

class Department {
  String name
  ...
}

I want to add boolean signature field for Order but by Department, so I need field signature by execDepartments for Order. Is it possible? Please help.

这是m:m 关系吗？

为什么不创建另一个域，比如

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belongTo

Is this an m:m relationship?

why not create another domain like

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]
}

Then you can write the belongTo
