猫鼬独特的领域 [英] Mongoose & unique field

问题描述

我的猫鼬具有以下架构:

I have the following schema with mongoose:

var SimSchema = new Schema({
    msisdn     : { type : String , unique : true, required : true },
    imsi       : { type : String , unique : true, required : true },
    status     : { type : Boolean, default: true},
    signal     : { type : Number },
    probe_name : { type:  String , required : true }
});

对于msisdn和imsi，我具有unique选项.

在某些情况下，此条件受到尊重. 对于以下mocha测试:

In some cases this condition is well respected. For the following mocha test:

"use strict";

var app      = require('../../app');
var http     = require('http');
var request  = require('supertest');
var mongoose = require('mongoose');
var should   = require('should');



describe('[ Sim controller ] ', function(){
  before(function(done) {
    app.set_env('test');
    this.server = app.start(function() {
      mongoose.connection.db.dropDatabase(function() {
        done();
      })
    });
  });


  beforeEach(function(done){
    done();
  });


  it('Sim with good parameters should be created in the database', function(done){
    var newSim = {
      msisdn:     '1234',
      imsi:       '007',
      probe_name: 'BOUCHON_1'
    };

    request(this.server)
      .post('/sims')
      .set('Content-Type', 'application/json')
      .send(newSim)
      .expect(200).end(function(err, res) {
        if (err) return done(err);
        res.body.should.have.property('imsi');
        res.body.should.have.property('probe_name');
        res.body.should.have.property('msisdn');
        setTimeout(function() {
          done();
        }, 1000);
      });
  });


  it('Sim imsi/msisdn is unique in the database', function(done){
    var newSim = {
      msisdn:     '1234',
      imsi:       '007',
      probe_name: 'BOUCHON_1'
    };

    request(this.server)
      .post('/sims')
      .set('Content-Type', 'application/json')
      .send(newSim)
      .expect(200).end(function(err, res) {
        if (err) return done(err);
        res.body.should.have.property('error').equal('Duplicate Item');
        done();
      });
  });


  after(function(done) {
    app.stop(done);
  });
});

如果直接运行它，效果很好:

It's working fine if I run it directly:

julio$ mocha test/controllers/ctrl_sim.js 

但是如果我通过隐性选项运行它，它将失败:

But If I run it thanks to the recessive option it failed:

  1) [ Sim controller ]  Sim imsi/msisdn is unique in the database:
     Uncaught AssertionError: expected { __v: 0,
  imsi: '007',
  msisdn: '1234',
  probe_name: 'BOUCHON_1',
  _id: '530a2b7f52273aa90783baf0',
  status: true } to have property 'error'

我在堆栈上读到，有时unique条件没有得到很好的遵守，因为索引没有刷新. 你认为这是我的情况吗?实际上，我删除了每个Mocha测试套件的数据库.也许mongo没有时间每次都重新创建所有索引.

I read on stack that sometimes the unique condition is not well respected as the index is not refreshed. Do you think this is my case? In fact, I delete the database for each mocha test suite. Maybe mongo doesn't have the time to recreate all the indexes each time.

有什么主意吗?

推荐答案

使用dropDups确保在诸如以下模式中删除重复记录；

Use dropDups to ensure dropping duplicate records in your schemas like;

var SimSchema = new Schema({
    msisdn     : { type : String , unique : true, required : true, dropDups: true },
    imsi       : { type : String , unique : true, required : true, dropDups: true },
    status     : { type : Boolean, default: true},
    signal     : { type : Number },
    probe_name : { type:  String , required : true }
});

在运行测试之前，请重新启动mongodb

And before running your tests, restart mongodb
