Question

我创建了一个名为 jobslist.js 的模式

 var mongoose = require('mongoose');
var Schema = mongoose.Schema;


var jobListSchema = new Schema({
    companyName: String,
    jobtitle: String,
    location: String
});

var joblist = mongoose.model('jobList', jobListSchema);

module.exports = joblist;

这是我的路由文件 user.js

    const jobList = require('../models/joblist');
        router.post('/appliedjobs', function(req,res) {
  console.log('posting applied jobs list');
  var appliedjob = new jobList();
      appliedjob.companyName = req.body.companyName;
      appliedjob.jobtitle =  req.body.jobtitle;
      appliedjob.location = req.body.location;
  console.log(appliedjob);
  appliedjob.save(function(err,joblist) {
    if(err) {
      console.log(err);
    } else {
      res.json({msg: 'job is saved'});
    }
  });
});

//get applied job list
router.get('/appliedjobs',function(req,res ) {
  console.log('getting applied jobs');
  appliedjob.find(function(err, appjobs) {
    if (err) {
      console.log('unable to get jobs '+ err);
    } else {
      console.log('getting list');
      res.json(appjobs);
    }
  });
});

我收到错误信息

我检查了我的数据库(MongoDB)，没有生成集合。

你应该修改 jobslist.js 文件的最后一行。

下面是正确导出mongoose模型。

module.exports = { jobList : mongoose.model('jobList', jobListSchema) };

导入时改变第一行

var JobList = require('../models/jobslist').jobList;
