如果我有两个模式,如:

var userSchema = new Schema({
    twittername: String,
    twitterID: Number,
    displayName: String,
    profilePic: String,
});

var  User = mongoose.model('User') 

var postSchema = new Schema({
    name: String,
    postedBy: User,  //User Model Type
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

我尝试将它们连接在一起,就像上面的例子,但我无法弄清楚如何做到这一点.最终,如果我可以做这样的事情,那将使我的生活变得非常轻松

var profilePic = Post.postedBy.profilePic
