javascript - Node 和 Sequelize 新手，并获得 "Unhandled rejection TypeError: Vacation.create is not a function"

Question

我正在尝试在我的node.js 项目中使用sequelize 播种数据。

我收到的错误是:

未处理的拒绝类型错误: Vacation.create 不是函数

我的 Node js 应用程序包含:

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',

            {

                    slug: 'rock-climbing-in-bend',
                    category: 'Adventure',

                    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)
})
});

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。

您应该直接导出假期:

假期.js

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