Grails hasOne和许多相同的域 [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] 
} 
  

但是当生成表时，组表中没有像leader_id这样的列。因此，领导关系并没有持续下去。

我应该如何解决这个问题？

解决方案

我需要的是

  class Team {
 belongsTo [leader：Person] 
 hasMany [成员：Person ] 
} 
 
 class Person {
 belongsTo [team：Team] 
} 
  

，以便Team表可以将所需的领导者引用返回给Person。

I have domain like this:

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

class Person {
 belongsTo [team: Team]
}

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.

How should I fix it?

解决方案

I figured that, what I need is

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

class Person {
 belongsTo [team: Team]
}

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