mongoose 创建表报错

Question

表模型

const mongoose = require("mongoose")

const groupChatSchema = new mongoose.Schema({
    groupID: { type: mongoose.Schema.Types.ObjectId, ref: "group" },
    msg_list: [
        { "msg": String, "type": String, "belong": { type: mongoose.Schema.Types.ObjectId, ref: "User" }, "date": { type: Date, default: Date.now() } }
    ]
})
module.exports = mongoose.model("groupChat", groupChatSchema);

创建表

exports.saveChat = async data => {
    let { id, message, token, type, chatType } = data
    let tokenRes = verifyToken(token)

    chatRes = await GroupChat.create({
                "groupID": id,
                "msg_list": [
                    { msg: message, type, belong: tokenRes.id, date: new Date() }
                ]
            })
}

有哪个大佬懂得怎么解决这个问题？

Answer 1

你传进去的数据和你的模型数据类型不匹配
