Question

是否可以让一个Schema引用Mongo中的另一个Schema？

我有以下内容，我希望Line架构中的用户成为UserSchema中的用户

var UserSchema = new Schema({
    name: {type: String, required: true},
    screen_name: {type: String, required: true, index:{unique:true}},
    email: {type: String, required: true, unique:true},
    created_at: {type: Date, required: true, default: Date}
});


var LineSchema = new Schema({
    user: [UserSchema],
    text: String,
    entered_at: {type: Date, required: true, default: Date}
});


var StorySchema = new Schema ({
    sid: {type: String, unique: true, required: true},
    maxlines: {type: Number, default: 10}, // Max number of lines per user
    title: {type: String, default: 'Select here to set a title'},
    lines: [LineSchema],
    created_at: {type: Date, required: true, default: Date}
});


var Story = db.model('Story', StorySchema);
var User = db.model('User', UserSchema);

是的，有可能

var LineSchema = new Schema({
    user: {type: Schema.ObjectId, ref: 'UserSchema'},
    text: String,
    entered_at: {type: Date, required: true, default: Date}
});

还有一句话，你为什么称他们为LineSchema和UserSchema？您可以将它们称为Line和User，它们代表一条线和一个用户：）
