我有2个域类,User和Dog(例如)
class User {
String id
Map<String, Dog> dogs
}
class Dog {
String name
}
我的控制器将json作为输入
{"key" : "dogKey", "userId" : "someId", "dogName" : "dog"}
def addDog(){
String key = request.JSON.key
User user = User.get(request.JSON.userId)
String dogName = request.JSON.dog
...
if(! user.dogs){
user.dogs = new HashMap<>(1)
}
user.dogs.put(key, new Dog(name: dogName))
user.save(flush: true)
}
运行用户数据@ Mongo后:
用户:
{ _id:....,
dogs: {
"dogKey": null
}...
}
有人可以解释一下我错过了什么吗?
谢谢!

可能是狗参考不保存在数据库中
def addDog(){
String key = request.JSON.key
User user = User.get(request.JSON.userId)
String dogName = request.JSON.dog
...
if(! user.dogs){
user.dogs = new HashMap<>(1)
}
Dog dog = new Dog(name: dogName)
dog.save(flush:true)
user.dogs.put(key, dog)
user.save(flush: true)
}
