Sequelize model.sync() 抛出错误

Question

我正在尝试使用sequelize 创建一个模型，然后添加，然后使用sync({force: true }) 如此处所示，使MySQL 创建表（如果不存在）。然而，它对我大喊大叫，说我的 MySQL 查询有错误（应该是由 Sequelize 生成的）。这是模型：

// admin.model.js
const { Sequelize, DataTypes } = require('sequelize');
const sequelize = require('../db/connection');
const validator = require("validator")

const Admin = sequelize.define('Admin', {
    email: {
        type: DataTypes.STRING,
        allowNull: false,
        unique: true,
        validate(value) {
            if (!validator.isEmail(value)) {
                throw new Error('Invalid email');
            }
        },
    },
    password: {
        type: DataTypes.STRING,
        allowNull: false,
        validate(value) {
            if (!value.match(/\d/) || !value.match(/[a-zA-Z]/)) {
                throw new Error('Password must contain at least one letter and one number');
            }
        },
        private: true, // used by the toJSON plugin
    },
    firstName: {
        type: DataTypes.STRING,
        allowNull: false
    },
    lastName: {
        type: DataTypes.STRING,
        allowNull: false
    },
    phone: {
        type: DataTypes.NUMBER
    },
}, {
    freezeTableName: true
}
)

module.exports = Admin;

这是我想要运行的函数

// sync.js
const Admin = require("../models/admin.model")

const synchronizeTables = async () => {
    try {
        await Admin.sync({ force: true })
        console.log("Admin Table synchronized")
    } catch (error) {
        console.error(error)
    }
}

module.exports = synchronizeTables

然后我在 db 目录中有一个 index.js 文件，用于导出连接和同步：

// index.js
const db = require("./connection");
const sync = require("./sync");

module.exports = { db, sync };

然后，我将它们导入 app.js 并运行同步

// app.js
const { db, sync } = require('./src/db');
sync()

当我运行服务器时出现错误：

    parameters: undefined
  },

因此，Sequelize 生成的 SQL 查询似乎存在错误。可能是我没用对吧。请帮助 ：）

Answer 1

所以这里的问题在于手机的数据类型。正如您所看到的，DataType.NUMBER 在查询中并没有变为 INTEGER，而是保留了 NUMBER，这在 SQL 中是不存在的。所以，我必须改变

phone: {
        type: DataTypes.NUMBER
    },

到

phone: {
        type: DataTypes.INTEGER
    },

另外，我使用sequelize.sync() 一次同步所有表，而不是逐一同步模型。
