Question

我试图通过使用mongoose＆＃34;找到＆＃34;从我的MongoDB获取文件。方法。但是我无法获得记录。它没有返回任何错误。这是我的代码

Server.js

var express     =   require('express');
var bodyparser  =   require('body-parser');
var mongoose    =   require('mongoose');
var cors        =   require('cors');

var app         =   express();

var http        =   require('http').Server(app);
var io          =   require('socket.io')(http);

mongoose.promise    =   global.promise;
mongoose.connect("mongodb://localhost:27017/testdb");
app.use(bodyparser.json());
app.use(cors());
app.use(express.static(__dirname + 'server'));

var api     =   require('./routes/apihandler')(app, express, io);

app.use('/alerts', api);

http.listen(3000, function(err){
  if(err) {
    console.log(err);
  } else {
    console.log('Listening PORT' + config.port);
  }
});

apihandler.js

var request     =   require('request');
var express     =   require('express');
var alertRoutes =   require('../../services/routes/alertRoutes');
var api         =   express.Router();

module.exports  =   function(app, express, io){
    api.get('/getAllAlerts/:retailerId/:loyaltyId', getAllAlerts);
    return api;
}

function getAllAlerts(req, res, callback) {
    console.log('apihandler');

    try {

        alertRoutes.getAllAlerts(req,res,callback);



    }
    catch(err) {
        res.send({"status" : "error",  message: err.mes});
    }

}

Manager.js

var alertModel          =   require('./../models/alertModel');
alertModel.find({}, function (err, docs) {
   console.log(err);
   console.log(docs);
});

Model.js

var mongoose = require('mongoose');

var alertSchema = new mongoose.Schema({
    id:{ type: String },
    alertType:{ type: Number},
    retailerId: { type: String },
    loyaltyId: { type: String }, 
    email: { type: String }, 
    description: { type: String},     
    locationId:{type: String }, 
    reason:{type: String},
    reasonDescription:{type: String},
    capturedReasonsList:mongoose.Schema.Types.Mixed
},{ collection: 'alerts' });

module.exports = mongoose.model('alerts', alertSchema);

alertRoutes.js

//Get all Alerts
function getAllAlerts(req, res, callback){
  console.log('getAllAlerts');
=
  var srchData  = {
      retailerId:req.params.retailerId,
      loyaltyId:req.params.loyaltyId
  };
 retailerId='+req.params.retailerId+'&loyaltyId='+req.params.loyaltyId;
  alertManager.getAlert(srchData,function(err,alertDetails){
    console.log('alertDetails',alertDetails);
      if (err) throw err;
      if(alertDetails && alertDetails.length > 0){
          res.status(200).send(alertDetails);
      }else{
          res.status(200).send({success: false,message: 'Alert Details not Found'});
      }
  });
// });
}

我可以进入经理js。但是查找查询无法正常工作

请帮我解决此问题。

谢谢。

Answer 1

试试这些代码。我正在使用这些代码＆amp;它对我有用。

型号：

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

  var alertSchema = mongoose.Schema({

    id:{ type: String },
    alertType:{ type: Number},
    retailerId: { type: String },
    loyaltyId: { type: String }, 
    email: { type: String }, 
    description: { type: String},     
    locationId:{type: String }, 
    reason:{type: String},
    reasonDescription:{type: String},
    capturedReasonsList:mongoose.Schema.Types.Mixed

  });
  mongoose.model('Alert',alertSchema);

服务器代码：

var mongoose = require('mongoose');
var alertModel = mongoose.model('Alert');
alertModel.find().exec(function (err, docs) {
   if(!err)
   console.log(docs);
});

Answer 2

也许这个查找从未被调用过...在查找之前做一些console.log以确保。

提供“getAlert”代码，我们无法看到Manager.js的使用位置和方式。

Node.Js mongoose发现不起作用
