我正在尝试添加约束以检查两个属性具有不同的值。

这是我的情况:

class Game { 
  static belongsTo = [ Team ] 
 
  Team teamHome 
  Team teamAway 
} 

static constraints = { 
  teamHome( notEqual: teamAway ) 
  teamAway( notEqual: teamHome ) 
} 

请您参考如下方法:

您可以使用 validator constraint:

static constraints = { 
  teamHome validator: { val, obj -> 
    val != obj.teamAway 
  } 
}
