grails - Grails-带有关联域类的自定义排序

Question

我有网域

培训

class Training {

       static belongsTo = [venue: Venue]
 }

地点

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

城市

 class City {
  String name
}

现在我想根据City name对Training进行排序。
Grails(Gorm)way有办法吗？

Answer 1

你有没有尝试过

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