Mongoose .populate()

Question

我是个初学者。

我有两个mongoose模式，orders和customers。

订单模式

const mongoose = require("mongoose");

const orderSchema = new mongoose.Schema({
    customer: {type: mongoose.Schema.Types.ObjectId, ref: "Customer"}    
});

module.exports = mongoose.model("Order", orderSchema);

customers模式

const mongoose        = require("mongoose"),
passportLocalMongoose = require("passport-local-mongoose");

const customerSchema = new mongoose.Schema({
    name: String,
    email: String
    username: String,
    password: String
});

customerSchema.plugin(passportLocalMongoose);
module.exports = mongoose.model("Customer", customerSchema);

这是我在插入新订单时的代码

const Orders = require("../models/orders");

Orders.create({customer: req.user});

我想使用.populate()来console.log()所有的订单和客户

以下是我的代码

Orders.find({}).populate("customers").exec((err, order) => {
    if(err) {
        console.log(err);
    } else {
        console.log(order);
    }
});

我想要获得客户的id、姓名和电子邮件，但问题是我只获得了客户的id

Answer 1

Orders.find({}).populate("customer").exec((err, order) => {
if(err) {
    console.log(err);
} else {
    console.log(order);
}
})

or you can try

    Orders.find({}).populate({path:"customer"}).exec((err, order) => {
if(err) {
    console.log(err);
} else {
    console.log(order);
}

})
