Question

是否可以有一个 Schema 来引用 Mongo 中的另一个 Schema？

我有以下内容，我希望 Line 模式中的用户成为 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);

Answer 1

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，你为什么叫他们LineSchema和UserSchema？你可以叫他们Line和User，毕竟他们代表了一条线路和一个用户:)
