Sequelize findOne()和SQL Server的问题(Trouble with Sequelize findOne() and SQL Server)

我是Sequelize的新手,并且正在尝试运行基本查询以在我的数据库中查找模型的第一个实例。 我的模型user.js

var Sequelize = require('sequelize');

var sequelize = new Sequelize('Northwind', 'username', 'password', {
    host: 'localhost',
    port: 1433,
    dialect: 'mssql'
});

var User = sequelize.define('Employees', {
    Name: Sequelize.STRING,
    createdAt: false,
    updatedAt: false
});

module.exports = User;

以及调用代码的Express.js应用程序中的文件api.js

router.route('/posts')
    .get(function (req, res) {
        var user;

        User.find({
            where: {
                Name: 'matt'
            }            
        }).then(function (user) {
        console.log('found');
    }, function(err){
        console.log(err);
    });
    res.send({
        message: 'Test string'
    });
});

我使用了值“Matt”,因为我知道它在Employees表中。 但是,在执行时,我收到的错误似乎表明Sequelize正在尝试从我知道在Employees表中不存在的列中SELECT ,如[id] [createdAt][updatedAt][updatedAt] 。 我相信它与findOne()命令有一个(default)执行,但我不知道如何配置。

任何指针将不胜感激!


I am new to Sequelize and was trying to run a basic query to find the first instance of model in my database. My model user.js:

var Sequelize = require('sequelize');

var sequelize = new Sequelize('Northwind', 'username', 'password', {
    host: 'localhost',
    port: 1433,
    dialect: 'mssql'
});

var User = sequelize.define('Employees', {
    Name: Sequelize.STRING,
    createdAt: false,
    updatedAt: false
});

module.exports = User;

And the the file, api.js, in my Express.js application where the code is called:

router.route('/posts')
    .get(function (req, res) {
        var user;

        User.find({
            where: {
                Name: 'matt'
            }            
        }).then(function (user) {
        console.log('found');
    }, function(err){
        console.log(err);
    });
    res.send({
        message: 'Test string'
    });
});

I used the value "Matt" for I know it is in the table Employees. However, upon executing, I receive errors about which seem to indicate that Sequelize is trying to SELECT from columns I know do not exist in the Employees table like [id], [createdAt], [updatedAt]. I believe it has to do with the findOne() command having a (default) execution, but I am not sure how to config.

Any pointers would be much appreciated!

定义(易失性)环境变量并在CMD中执行命令:

set "ENV=development"
gulp

在一行中:

set "ENV=development" & gulp

定义(易失性)环境变量并在PowerShell中执行命令:

$env:ENV = 'development'
& gulp

在一行中:

$env:ENV = 'development'; & gulp

Defining a (volatile) environment variable and executing a command in CMD:

set "ENV=development"
gulp

In one line:

set "ENV=development" & gulp

Defining a (volatile) environment variable and executing a command in PowerShell:

$env:ENV = 'development'
& gulp

In one line:

$env:ENV = 'development'; & gulp
