工厂女孩设置了续集适配器

Question

我在做什么

我正在使用带有 sequelize 适配器的 factory girl 来测试 Mocha。我知道我在设置上做错了但无法解决问题。

这是我的代码：

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);
  });
});

** 我得到了什么错误 **

TypeError: Model.build is not a function

所以我知道这与模型没有 return 作为构造函数有关。但是如何使它 return 成为构造函数呢？

如果我按如下方式更改工厂中的 require 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 factory.define 不是函数。

我希望这更清楚...但是当您 define 一个工厂时，需要传入一个 FUNCTION CONSTRUCTOR。

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。但关键是我需要为模型传递构造函数。
