英文:
Using golang's mgo library, how do you retrieve nested objects such as lists
问题
我正在尝试检索填充此类的对象：
type Room struct {
Name string
People []Person
Chat []ChatMessage
Me Person
}
数据字段"People"显示为空切片[]。我正在使用简单的查找来获取数据。
result := Room{}
err = c.Find(bson.M{"name": "dev"}).One(&result)
我做错了什么？

基本上，只需要在People []Person行的末尾添加 'bson: "<mongodb_class_name>"'

I am trying to retrieve an object that fills this class:
type Room struct {
Name string
People []Person
Chat []ChatMessage
Me Person
}
The data field "People" comes up as an empty slice []. I am using a simple find to get the data.
result := Room{}
err = c.Find(bson.M{"name": "dev"}).One(&result)
What am I doing wrong?

Basically, just need to add 'bson: "<mongodb_class_name>"' at the end of the People []Person line
