Sequelize关联错误include.model.getTableName不是一个函数

Question

你好，我是nodejs的新手，目前我将Sequelize与NodeJs集成在一起。我制作了不同的模型并定义了关联，但是当我获取数据时，我收到了以下错误消息

  

TypeError：include.model.getTableName不是函数

我的盒子模型

const Sequelize = require('sequelize');
const PostBox = require("./PostBox");
module.exports = function (sequelize) {
    var Box = sequelize.define('box', {
        id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true,
            references: {
                model: PostBox,
                key: "box_id" // this is the `posts.post_id` column - name it according to your posts table definition (the one defined in ./Post)
            }
        }
    }, {timestamp: false});
    Box.associate = function (models) {
        Box.hasMany(models.PostBox, {targetKey: 'user_posts_id',foreginkey: 'id'});
    };
    return Box;
};

邮箱模型

const Sequelize = require('sequelize');

var Post = require('./Post');

module.exports = function (sequelize) {
    var PostBox = sequelize.define('user_posts_boxes', {
        id: {
            type: Sequelize.INTEGER,
            primaryKey: true
        },
        user_posts_id: {
            type: Sequelize.INTEGER,
            references: {
                model: Post,
                key: "id" // this is the `posts.post_id` column - name it according to your posts table definition (the one defined in ./Post)
            }
        },
        box_id: {
            type: Sequelize.INTEGER,
        },
        user_id: {
            type: Sequelize.INTEGER
        },
        post_type_id: {
            type: Sequelize.INTEGER
        }

    }, {timestamp: false}
    );
    PostBox.associate = function (models) {
        PostBox.belongsTo(models.Post, {targetKey: 'id', foreignKey: 'user_posts_id'});
    };
    return PostBox;
};

这是我从中调用关联模型的基本模型

const Sequelize = require('sequelize');
var Box = require('./Box');

const sequelize = new Sequelize('store_db', 'root', 'root', {
    host: 'localhost',
    dialect: 'mysql'
});

const User = require("./User")(sequelize);
const PostBox = require("./PostBox")(sequelize);
const Post = require("./Post")(sequelize);

function findOneUer() {
    return  User.findOne({attributes: ['id', 'username']});
}

function findPostById(id) {
    var post = PostBox.findOne({
        attributes: ['id', "user_posts_id", "box_id"],
        where: {id: id},
        include: [
            {model: Box, required: true}
        ]

    });
    return post;
}
module.exports = {findPostById: findPostById};

当我从基本模式调用 findPostById（2）方法时，我收到了此错误。
