无法读取未定义的属性“同步" [英] Cannot read property 'sync' of undefined

问题描述

我正在学习如何使用 hapi 服务器和其他一些包在 Nodejs 中设置基本 mvc 的教程.

I am following a tutorial on how to set up a basic mvc in Nodejs using the hapi server and a few other packages.

教程:https://www.sitepoint.com/node-js-mvc-application/

我的项目的 Git:https://github.com/christoph88/node-js-mvc-tut/

当我尝试启动服务器时出现错误:

I have an error when I try to launch the server:

~/Projects/node-js-mvc-tut$ node server.js 
/home/christoph/Projects/node-js-mvc-tut/server.js:33
Models.sequelize.sync().then(() => {
^
TypeError: Cannot read property 'sync' of undefined

模型是在需求中定义的.我不明白为什么同步未定义.在 lib/index.js 文件中需要 Sequelise.

Model is defined within the requirements. I do not understand why sync is undefined. Sequelise is required within the lib/index.js file.

'use strict';

const Hapi = require('hapi');
const Hoek = require('hoek');
const Path = require('path');
const Settings = require('./settings');
const Routes = require('./lib/routes');
const Models = require('./lib/models/');

const server = new Hapi.Server();

server.connection({ port: Settings.port });

server.register([
    require('vision'),
    require('inert')
], (err) => {
  Hoek.assert(!err, err);

  server.views({
    engines: { pug: require('pug') },
    path: Path.join(__dirname, 'lib/views'),
    compileOptions: {
      pretty: false
    },
    isCached: Settings.env === 'production'
  });

  // Add routes
  server.route(Routes);
});

Models.sequelize.sync().then(() => {
  server.start((err) => {
    Hoek.assert(!err, err);
    console.log(`Server running at: ${server.info.uri}`);
  });
});

有人可以帮我解决这个问题吗?让它运行会很棒，这样我就可以尝试使其适应我的需求.

Can somebody help me with this? Would be great to get this running so I can try to adapt it to my needs.

推荐答案

我通过将我的 index.js 文件移动到模型文件夹来让它工作.

I have got it working by moving my index.js file to the models folder.

此文件包含在模型中分派续集从而解决问题的必要脚本.

This file has the necessairy scripts that dispatches sequelise in the model thus fixing the problem.
