所以我有这样的架构:
getWindow().setBackgroundDrawable
和
var article = new mongoose.Schema({
title : String,
comments : [{
pe: mongoose.Schema.Types.ObjectId,
ref: 'Comment'
}]
});
现在我有了我的小角度应用程序,当我使用我的API和文章检索时,我得到类似的东西:
var comment = new mongoose.Schema({
created : Date,
text : String
});
现在在前端我推了一些评论,新对象是:
{
title : "please help me"
comments : []
}
当我调用API并更新文档时,我希望mongo能够自己创建子对象注释,有没有办法? 它应该自动完成吗?

我会用这种方式写一篇文章架构(免责声明:我没有尝试过猫鼬):
var article = new mongoose.Schema({
_id: String // or mongodb.ObjectId? I'm not sure.
title : String,
comments : [{
_id: String // this field is not nessesary
text: String,
date: String
}]
});
var comment = new mongoose.Schema({
created : Date, // created or date?
text : String
});
当你用api检索时,你会得到类似的东西:
{
"_id": "ndrjgnd..fesf",
"title": "grdgrdgr",
comments: [ {"text": "hello", "created": "2016:...:"}, ... , ]
}
然后你可以从前端推送新的评论:
{
"articleId": "ndrjgnd..fesf", // this is important.
"text": "balabala"
}
并更新db:db.article.update( {_id: ariticleId}, {$push: newComment})
