Question

我正在尝试创建问题跟踪器。其中包含以下结构。

const mongoose = require('mongoose')
const Schema = mongoose.Schema

const time = require('../libs/timeLib')

let newRecord =  new Schema(
    {
        title:{type: String, default: ''},
        issueType: [],
        description: {type: String},
        issueLocation: {type: String},
        createdBy: {type: String, index: true},
        issueId: {type: String, unique: true},
        issueCreatedOn: {type: Date, default: time.now()},
        status: {
            open: {type: Boolean, default: false},
            closed: {type: Boolean, default: false}
        },
        screenshots: []
    }
)

module.exports = mongoose.model('Record', newRecord)

我编写了以下代码来创建新记录。我能够第一次创建记录。但是当我第二次尝试使用相同的createdBy创建相同的东西时。我收到以下错误我正在使用Postman与API进行交互

E11000重复键错误集合：issueTrackingDB.records索引： userId_1重复键：{：null}

在下面查看为创建而创建的功能

let createIssue = (req, res)=>{

    let createNewRecord = () =>{
        return new Promise((resolve, reject)=>{
            let newIssue = new RecordModel({
                title: req.body.title,
                description: req.body.description,
                issueLocation: req.body.issueLocation,
                createdBy: req.body.fullName, 
                issueId: shortid.generate(),
                issueCreatedOn: time.now(),
            })

            let issueType = (req.body == undefined || req.body.issueType == null || req.body.issueType == '')? []: req.body.issueType.split(',')
            newIssue.issueType = issueType

            let screenshots = (req.body == undefined || req.body.screenshots == null || req.body.screenshots == '')? []: req.body.screenshots.split(',')
            newIssue.screenshots = screenshots

            newIssue.save((err, issueDetails)=>{
                if(err){
                    logger.error(err.message, ' recordsController, createIssue', 8)
                    let apiResponse = response.generate(true, "Failed To Create Issue", 500, null)
                    reject(apiResponse)
                } else {
                    issueDetails.status.open = true
                    resolve(issueDetails)
                }
            })
        })
    } // end create new record


createNewRecord((resolve)=>{
    console.log("Issue Created Successfully")
    let apiResponse = response.generate(false, "Issue Created Successfully", 
    200, resolve)res.send(apiResponse)
        })
.catch((err)=>{
    console.log(err)
    console.log("Some Error occured")
    res.send(err)
        })
} // end create new issue

Answer 1

您在“ issueId：{type：String，unique：true}”上具有唯一键，请确保每次调用时值都更改或删除唯一键
