Grails hasOne 和 hasMany 相同的域 [英] Grails hasOne and hasMany same domain

问题描述

我有这样的域名:

class Team {
 hasOne [leader: Person]
 hasMany [member: Person]
}

class Person {
 belongsTo [team: Team]
}

但是生成表的时候，team表中没有leader_id这样的列.因此领导关系不会持久化.

But when the tables are generated, there is not a column like leader_id in the team table. And thus the leader relation is not persisted.

我该如何解决?

推荐答案

我想，我需要的是

class Team {
 belongsTo [leader: Person]
 hasMany [member: Person]
}

class Person {
 belongsTo [team: Team]
}

这样 Team 表就可以将所需的领导者"引用回 Person.

so that the Team table can have the desired "leader" reference back to Person.
