Sequelize.js 使用sequelize适配器设置factory girl

我在做什么

我正在使用带有sequelize适配器的factory girl进行摩卡测试。我知道我的设置有问题，但无法解决问题

这是我的密码：

模态：

"use strict";

module.exports = (sequelize, DataTypes) => {
  const Region = sequelize.define("Region", {
    name: {
      type: DataTypes.STRING,
      allowNull: false
    },
    open: {
      type: DataTypes.BOOLEAN,
      allowNull: false
    },
    description: {
      type: DataTypes.STRING,
      allowNull: true
    }
  });
  Region.associate = models => {
    Region.hasMany(models.Area, {
      foreignKey: "regionId",
      as: "areas"
    });
  };
  return Region;
};

工厂：

var factory = require("factory-girl");
const adapter = new factory.SequelizeAdapter();
factory = factory.factory;
factory.setAdapter(adapter);

const Region = require("../../src/models/region");

factory.define("region", Region, () => {
  return {
    name: factory.chance("first"),
    open: "true",
    description: factory.chance("sentence", { words: 5 })
  };
});

工厂的索引文件：

import factory from "factory-girl";

import "./regions";
import "./areas";

global.factory = factory;

export default factory;

我的摩卡测试文件：

import chai from "chai";
import assert from "assert";
import app from "../../src/app";
import chaiHttp from "chai-http";
import factories from "../factories";
// import dotenv from "dotenv";
// dotenv.config({path: ".env.test"});
chai.use(chaiHttp);

describe("'regions'service", () => {
  it("should POST area", async () => {
    const region = await factories.create("region");
    const dummy = {
      name: "New area",
      open: true,
      description: "This is a cool area!",
      gps: "122.123, 123.4123",
      regionId: region.dataValues.id
    };
    const res = await chai
      .request(app)
      .post("/api/areas")
      .send(dummy);
    console.log(res.body);
    assert.equal(res.body.name, dummy.name);
  });
});

**我会犯什么错误**

TypeError:Model.build不是函数

所以我明白了，这和模型不能作为构造函数返回有关。但是如何让它返回构造函数呢

如果我在工厂按以下方式更改所需方法：

var factory = require("factory-girl");
const adapter = new factory.SequelizeAdapter();
factory = factory.factory;
factory.setAdapter(adapter);
const sequelize = require("sequelize");
const DataTypes = sequelize.DataTypes;

const Region = require("../../src/models/region")(sequelize, DataTypes);

factory.define("region", Region, () => {
  return {
    name: factory.chance("first"),
    open: "true",
    description: factory.chance("sentence", { words: 5 })
  };
});

---

然后我得到错误

工厂。define

不是一个函数

我希望这能说得更清楚些。。。但是当您定义工厂时，需要传入函数构造函数

const Region = require("../../src/models").Region;

如果您定义上面列出的模型，这将是一种方法。但关键是我需要传递模型的构造函数
