Question

我有一个在MEAN堆栈中使用的员工信息模型，并希望在商店模型中引用他们将要工作的商店名称，以下是正确的吗？

雇员：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var muv = require('mongoose-unique-validator');

var schema = new Schema({
    firstName: {type: String, required: true},
    lastName: {type: String, required: true},
    empId: {type: String, required: true, unique: true},
    num: {type: String, required: true},
    job: {type: String, required: true},
    store: {type: Schema.Types.storeName, ref: 'Stores'},
});

schema.plugin(muv);

module.exports = mongoose.model('Message', schema);

商户：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var schema = new Schema({
    storeName: {type: String, required: true},
    lat: {type: String, required: true},
    long: {type: String, required: true},
});

module.exports = mongoose.model('Stores', schema);

你关闭了！您想要引用商店的ID，而不是名称。当Mongoose执行“加入”时，它会在store个人资料字段中看到ObjectID商店，并将其与Stores集合中的ObjectID相匹配。

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var muv = require('mongoose-unique-validator');

var schema = new Schema({
    firstName: {type: String, required: true},
    lastName: {type: String, required: true},
    empId: {type: String, required: true, unique: true},
    num: {type: String, required: true},
    job: {type: String, required: true},
    store: {type: type: Schema.ObjectId, ref: 'Stores'},  //Reference store ObjectId.
});

schema.plugin(muv);

module.exports = mongoose.model('Message', schema);

如何在ExpressJs中引用其他模型值？
