hibernate - 没有正确的引用->删除问题

Question

假设我们有两个GORM类

class Team {
    static hasMany = [users: User]
    User createdBy // User who created this Team
}
class User {
    static belongsTo = [team: Team]
}

Grails错误地将createBy-User与Team关联。
如果我删除团队，Grails会将删除操作级联到createdBy-User，这不是故意的!

我该如何预防？

Answer 1

class Team {
    static hasMany = [users: User]
    User createdBy // User who created this Team

 static mapping = {
            createdBy(cascade: 'none')  //only save and update cascade is allowed
            user cascade:'all-delete-orphan'  //remove other user references 
    }

}

希望您有解决方案!
