Sequelize.js Sequelizejs:未处理的拒绝SequelizeDatabaseError:列user.playerstatsId不存在

我有一个现有的数据库，我想从表“User”中检索，但是User表与“PlayerStats”表有一对一的关系。我想将用户对象以及它的Playerstats作为Json对象而不是外键Id检索。在编写代码并运行代码后，控制台中出现一个错误，显示：

Unhandled rejection SequelizeDatabaseError: column user.playerstatsId does not exist

据我所知，我觉得sequelize正在尝试将用户和Playerstats表连接在一起

这是我的用户代码：

  var Sequelize = require('sequelize');

var db = require('../database/postgres');


var User =db.define('user', {

    id: {
        type: Sequelize.INTEGER,
        allowNull: false,
        primaryKey: true
    },

    address: {
        type: Sequelize.STRING,
        field: 'address'
    },

    bio: {
        type: Sequelize.STRING,
        field: 'bio'
    },

    country: {
        type: Sequelize.STRING,
        field: 'country'
    },

    email: {
        type: Sequelize.STRING,
        field: 'email'
    },

    firstname: {
        type: Sequelize.STRING,
        field: 'firstname'
    },

    gender: {
        type: Sequelize.STRING,
        field: 'gender'
    },

    lastname: {
        type: Sequelize.STRING,
        field: 'lastname'
    },

    locked: {
        type: Sequelize.BOOLEAN,
        field: 'locked'
    },

    money: {
        type: Sequelize.DOUBLE,
        field: 'money'
    },

    onlinestatus: {
        type: Sequelize.STRING,
        field: 'onlinestatus'
    },

    password: {
        type: Sequelize.STRING,
        field: 'password'
    },

    phonenumber: {
        type: Sequelize.STRING,
        field: 'phonenumber'
    },

    picture: {
        type: Sequelize.STRING,
        field: 'picture'
    },

    username: {
        type: Sequelize.STRING,
        field: 'username'
    },

    usertype: {
        type: Sequelize.STRING,
        field: 'usertype'
    },



}, {
    tableName: 'users',

    timestamps: false
});


module.exports = User;

我的PlayerStats代码：

    var Sequelize = require('sequelize');

var db = require('../database/postgres');


var PlayerStats =db.define('playerstats', {

    id: {
        type: Sequelize.INTEGER,
        field: 'id',
        allowNull: false,
        primaryKey: true
    },

    time: {
        type: Sequelize.DATE,
        field: 'time'
    },

    expenses: {
        type: Sequelize.DOUBLE,
        field: 'expenses'
    },

    friends: {
        type: Sequelize.INTEGER,
        field: 'friends'
    },

    loss: {
        type: Sequelize.INTEGER,
        field: 'loss'
    },

    matchplayed: {
        type: Sequelize.INTEGER,
        field: 'matchplayed'
    },

    profit: {
        type: Sequelize.DOUBLE,
        field: 'profit'
    },

    readmessage: {
        type: Sequelize.INTEGER,
        field: 'readmessage'
    },

    referrals: {
        type: Sequelize.INTEGER,
        field: 'referrals'
    },

    referrer: {
        type: Sequelize.INTEGER,
        field: 'referrer'
    },

    totalmessage: {
        type: Sequelize.INTEGER,
        field: 'totalmessage'
    },

    unreadmessage: {
        type: Sequelize.INTEGER,
        field: 'unreadmessage'
    },

    wallet: {
        type: Sequelize.DOUBLE,
        field: 'wallet'
    },

    wins: {
        type: Sequelize.INTEGER,
        field: 'wins'
    }

}, {
    tableName: 'playerstats',

    timestamps: false
});


module.exports = PlayerStats;

最后一个运行它们的主js类：

    var io = require('socket.io')(process.env.PORT || 4000);

var User = require('./server/entities/user');

var PlayerStats = require('./server/entities/playerstats');





new Server();

const room = 'quick-chat';

function Server() {


    User.belongsTo(PlayerStats,{as: 'playerstats'});


    User.findOne({include: [{

        model: PlayerStats,

        as: 'playerstats'

    }]}).then(function (user) {

        console.log(user);

    });


    var global = this;



    io.on('connection',function(socket){

        console.log("A client has connected");

        socket.on('join', (data) => {

            //todo connect to the gambeat db and update the users info to online

            socket.join(room);

            console.log("client has joined");

        });

        socket.on('disconnect', () => {

            console.log("client has disconnect");

        });

    });



}

你能告诉我怎么做吗

我找到了问题所在，基于此

默认情况下，将根据目标型号名称和目标主键名称生成belongsTo关系的外键。 默认大小写为camelCase，但是如果源模型配置了下划线：true，则foreignKey将为snake_大小写

这导致了“playerstatsId”，而我的用户表中没有它。您可以通过使用外键选项为外键指定正确的名称来更正此问题。因此

User.belongsTo(PlayerStats,{foreignKey: 'playerstats',as: 'playerstat'});
