grails - Grails - 与相关域类的自定义排序

Question

我有域名

训练

class Training {

       static belongsTo = [venue: Venue]
 }

场地

  class Venue {
        static belongsTo = [city: City]
  }

城市

 class City {
  String name
}

现在我想根据City name. 有没有办法在 Grails (Gorm) 方式中做到这一点？

你有没有尝试过

def results = Training.withCriteria {
    order('venue.city.name', 'asc')
}
