为猫鼬中的字段设置严格值

Question

我想为 mongoose 中的字段设置严格的值，例如在下面的模式中

var Option_Sets = new Schema({
    setId: {
        type: mongoose.Schema.ObjectId,
        default: mongoose.Types.ObjectId,
        required: true,
        dropDups: true,
        index: true
    },
    setName: { type: String },
    scope: String,
    components: [Schema.Types.Mixed]
});

我想设置scope字段在scope数组中只能取一个

var scopes = ["Global", "Store View", "Website"];

有人可以帮我举个例子并指导我如何去做吗？提前致谢

为了执行这个尝试枚举：

var Option_Sets = new Schema({
    setId: {
        type: mongoose.Schema.ObjectId,
        default: mongoose.Types.ObjectId,
        required: true,
        dropDups: true,
        index: true
    },
    setName: { type: String },
    scope: {
        type: String,
        enum: ["Global", "Store View", "Website"]
    },
    components: [Schema.Types.Mixed]
});
