“不赞成使用mpromise(猫鼬的默认诺言库)".测试时出现错误 [英] "mpromise (mongoose's default promise library) is deprecated" error when testing

问题描述

一段时间以来，我一直收到此错误，我决定今天进行修复，但是尝试修复一个小时后，我可以找到解决方案.

For a while I have been getting this error and I decided to fix it today but after an hour trying to fix it I can find the solution.

当我测试猫鼬用户模型时，会生成此错误/警告:

When I test my mongoose User model this error/warning is generated:

Mongoose: mpromise (mongoose's default promise library) is deprecated, plug in your own promise library instead: http://mongoosejs.com/docs/promises.html

这是我的考试:

  1 var assert = require('chai').assert;
  2 var mongoose = require('mongoose');
  3 var clearDB = require('mocha-mongoose')(require('../../config/database').uri, { skip: ['workouts'] });
  4 var database = require('../../config/database').connect;
  5
  6 var User = require('../../app/models/user');
  7 var user = new User({});
  8
  9 var req_body = {
 10   username: "garyvee",
 11   email: "[e-mail]",
 12   password: "secret"
 13 };
 14
 15 describe('User', function() {
 16   beforeEach(function(done) {
 17     user.username = "johnsmith";
 18     user.email = "[e-mail]";
 19     user.password = "secret";
 20     done();
 21   });
 22
 23   it('can be saved', function() {
 24     return user.save(function(err: any) {
 25       assert.isNull(err);
 26     })
 27   });
 28 });

我认为它与.save有关，但我不知道如何解决.有人可以帮我，告诉我如何解决它，以便不显示错误/警告.

I think it has something to do with the .save but I don't know how to fix it. Can someone help me and tell me how to fix it so that error/warning isn't shown.

推荐答案

您需要插入一个Promise库(q，bluebird，es6一个...)

You need to plugin a promise library (q, bluebird, the es6 one...)

mongoose.Promise = require('bluebird');
