ReferenceError：在初始化猫鼬之前无法访问“用户”

Question

这个错误由​​猫鼬显示 在 order.model.js:6:52 初始化之前无法访问“用户”

但用户已经在那里

order.js

import mongoose from 'mongoose';
import Product from './product.model.js';
import User from './users.model.js';

const orderSchema = new mongoose.Schema({
    user: { type: mongoose.SchemaTypes.ObjectId, ref: User },
    products: [{ type: mongoose.SchemaTypes.ObjectId, ref: Product }],
    status: { type: String, required: true },
});

const Order = mongoose.model('Order', orderSchema);

export default Order;

user.js

import mongoose from 'mongoose';
import Order from './order.model.js';

const userSchema = new mongoose.Schema({
    fname: { type: String, required: true },
    lname: { type: String, required: true },
    email: { type: String, required: true },
    phone: { type: Number, required: true },
    password: { type: String, required: true },
    orders: [{ type: mongoose.SchemaTypes.ObjectId, ref: Order }],
});

const User = mongoose.model('User', userSchema);

export default User;

Answer 1

不需要导入用户模型，试试下面的代码

user: { type: mongoose.SchemaTypes.ObjectId, ref: 'User' },
