问题描述
我开始学习如何使用 Nodejs、.我的问题: 启动服务器后，Expressjs、Sequelize 和 MySQL 构建 Rest API代码>MysqlworkbenchSequelize 没有创建表，Mysqlworkbench 中也没有表.只是这条消息出现在下面...感谢您提前提供任何指导或帮助:-
I started to learn how to build Rest API using Nodejs,Expressjs,Sequelize and MySQL using Mysqlworkbench.
My Problem: After I start the server, the table is not created by Sequelize and no table in Mysqlworkbench also. Just this message appeared below... Thanks for any guide or help in advance:-

推荐答案
由于您的 product 模型位于单独的文件中，您需要使用 import 方法导入它在 sequelize 实例上可用，如下所示
since your product model is in a separate file you are required to import it using the import method available on sequelize instance as follows
模型product.js
module.exports = function(sequelize, Sequelize) {
const Product = sequelize.define('product', {
id: {
type: Sequelize.INTEGER,
autoIncrement: true,
allowNull: false,
primaryKey: true
},
title: Sequelize.STRING,
price: {
type: Sequelize.DOUBLE,
allowNull: false
},
imageUrl: {
type: Sequelize.STRING,
allowNull: false
},
description: {
type: Sequelize.STRING,
allowNull: false
}
});
module.exports = Product;
};
dbconfig.js
const Sequelize = require('sequelize');
const sequelize = new Sequelize('node','root','1234567890', {
operatorsAliases: false ,
dialect: 'mysql',
host:'localhost'
});
sequelize.import('path/to/product/model');
module.exports = sequelize;
