Question

我正在尝试使用我的node.js项目中的sequelize来播种数据。

我得到的错误是：

未处理拒绝TypeError：Vacation.create不是函数

我的节点js app包含：

Vacation = require('./models/vacation.js');
var app = express();
var Sequelize = require('sequelize');

sequelize.sync().then(function () {
  Vacation.create({
            // insert new user
                    name: 'Hood River Day Trip',
                    slug: 'hood-river-day-trip',
                    category: 'Day Trip',
                    sku: 'HR199',
                    description: 'Spend a day sailing on the Columbia and ' +
                            'enjoying craft beers in Hood River!',
                    priceInCents: 9995,
                    tags: ['day trip', 'hood river', 'sailing', 'windsurfing', 'breweries'],
                    inSeason: true,
                    maximumGuests: 16,
                    available: true,

            },
            {

                    slug: 'oregon-coast-getaway',
                    category: 'Weekend Getaway',

                    available: true,
                    packagesSold: 0,
            },
            {
                    name: 'Rock Climbing in Bend',
                    slug: 'rock-climbing-in-bend',
                    category: 'Adventure',
                    sku: 'B99',
                    description: 'Experience the thrill of rock climbing in the high desert.',
                    priceInCents: 289995,
                    tags: ['weekend getaway', 'bend', 'high desert', 'rock climbing', 'hiking', 'skiing'],
                    inSeason: true,
                    requiresWaiver: true,
                    maximumGuests: 4,
                    available: false,
                    packagesSold: 0,
                    notes: 'The tour guide is currently recovering from a skiing accident.'
        }).success(function (data) {
 console.log(data.values)
})
});

和我的模型vacation.js包含

var Sequelize = require('sequelize');

module.exports = function (sequalize) {
 var Vacation = sequelize.define("Vacation", {
    name:               Sequelize.STRING,
    slug:               Sequelize.STRING,
    category:       Sequelize.STRING,
    sku:                    Sequelize.STRING,
    description:    Sequelize.STRING,
    priceInCents: Sequelize.INTEGER,
    tags: [Sequelize.STRING],
    inSeason:           Sequelize.BOOLEAN,
    available:          Sequelize.BOOLEAN,
    requiresWaiver: Sequelize.BOOLEAN,
    maximumGuests:  Sequelize.INTEGER,
    notes:                  Sequelize.STRING,
    packagesSold:   Sequelize.INTEGER,
    });
return {
    Vacation: Vacation
};
};

Answer 1

vacation.js导出并具有Vacation属性的对象。这意味着导入：

Vacation = require('./models/vacation.js');

接收一个具有Vacation属性但没有create属性的对象。

您应该直接导出Vacation：

<强> vacation.js

module.exports = function(sequelize) {
  var Vacation = sequelize.define('Vacation', {
    // Model field definitions
  });
  return Vacation;
};

新节点和续集并获得＆＃34;未处理的拒绝TypeError：Vacation.create不是函数＆＃34;
