Question

我已经使用angular-fullstack-generator 4.0.1构建了ExpressJS API端点。当我对现有数据发送PUT请求时，API返回200，但MongoDB中没有变化 - 数据保持不变。我没有PUT返回200，数据没有变化。 GET和POST工作正常，没有任何问题。

我对MEAN堆栈很新，所以我可能会遗漏一些非常简单的东西。

服务器/ API /响应/ index.js：

'use strict';

var express = require('express');
var controller = require('./response.controller');

var router = express.Router();

router.get('/', controller.index);
router.get('/:id', controller.show);
router.post('/', controller.create);
router.put('/:id', controller.upsert);
router.patch('/:id', controller.patch);
router.delete('/:id', controller.destroy);

module.exports = router;

服务器/ API /响应/ response.model.js：

'use strict';

import mongoose from 'mongoose';

var ResponseSchema = new mongoose.Schema({
    created_at: Date,
    userResponse: Object
});

export default mongoose.model('Response', ResponseSchema);

服务器/ API /响应/ response.controller.js：

//...
// Upserts the given Response in the DB at the specified ID
export function upsert(req, res) {
  if(req.body._id) {
    delete req.body._id;
  }
  return Response.findOneAndUpdate(req.params.id, req.body, {upsert: true, setDefaultsOnInsert: true, runValidators: true}).exec()

    .then(respondWithResult(res))
    .catch(handleError(res));
}
//...

GET api / responses / 57aa6b6845078181549f703f结果：

现在为PUT。

PUT api / responses / 57aa6b6845078181549f703f 请求有效负载 请注意我是如何做出一些更改的（添加了howManyOthers等）

{"_id":"57aa6b6845078181549f703f","userResponse":{"name":"Kite","age":"30","existsOtherPerson":"There will be me and others","howManyOthers":"2 more people","ownedHomeBefore":"","shortSaleOrForeClosure":"","foreClosureYearsAgo":"","proceed":"","deadend":"","shortSaleYearsAgo":"","proceed2":"","deadend2":"","neitherShortOrForeClosureOverThreeYearsAgo":"","haveBankruptcy":"","bankruptcyType":"","dischargeYears":"","proceed3":"","deadend3":"","incomeSource":"","timeAtJobMoreThanTwoYears":"","timeAtJobMonths":"","previousEmployerPaidHow":"","previousEmployerGrossPaycheck":"","2WeekPaycheck":"","havePartTimeJob":"","partTimeJobMoreThan2Years":"","partTimeJobPaidHow":"","partTimeJobGrossPaycheck":"","otherIncomeSources":"","hasCashAssets":"","cashAssetValue":"","hasPropertyAssets":"","stillOwnPropertyAssets":"","propertyAssetMonthlyPayment":"","propertyAssetYearsOfPayments":"","hasRetirementAssets":"","retirementAssetsValue":"","monthlyRent":"","monthlyCreditCard":"","hasCarPayment":"","monthlyCar":"","hasStudentLoans":"","monthlyStudentLoan":"","deferredTime":"","hasOtherMonthlyPayments":"","creditScore":"","coApplicantReady":"","coApplicantFirstName":"","coApplicantEmail":"","phoneNumberFutureContact":"","phoneNumber":"","otherCoApplicantsReady":"","firstCoApplicantFirstName":"","firstCoApplicantEmail":"","secondCoApplicantFirstName":"","secondCoApplicantEmail":"","phoneNumberFutureContact2":""}}

快速控制台

(node:23321) Warning: a promise was created in a handler but was not returned from it
PUT /api/responses/57aa6b6845078181549f703f 200 23.753 ms - -

当我再次进行GET时，它在PUT之前的结果相同。我能做错什么？

请告诉我如何进一步澄清这个问题。

编辑：一旦我压缩我的模型和有效负载，PUT就可以工作了。所以问题在于Mongoose如何更新对象。

ExpressJS API PUT返回200但未更新MongoDB
