How to fetch data from mongodb and show using node.js

Question

Following is my code to fetch data from a collection and show it on index page, but it is not giving the results.

Node Code-

var app = require('express')();
var mongoose = require('mongoose');
var dbURI = 'mongodb://localhost/test';

mongoose.connect(dbURI);
var testSchema = new mongoose.Schema({
        name: String,
        rollnum: String
});

var Test = mongoose.model('Test', testSchema);

app.get('/', function(req, res){
        Test.find({},function(err, docs){
                res.send('index',{docs:docs});
        });
        //res.send('test');
});

app.listen(3001);

However I check and have a collection in db like this -

Query fire - db.testinfo.find()

Output -

{
"_id": ObjectId("123456..78"),
"name": "test",
"rollnum": "XXXX"
}

After hitting the URL - http://127.0.0.1:3001/

This is the output I am getting -

{
  "docs": []
}

However I was expecting to get the result of name, rollnum.

Please let me know what I am doing wrong.

When you register a model in Mongoose, it uses the pluralized, lower-cased model name as the name of the collection it's tied to. So because your model name is Test, the collection name is tests.

To tie the model to testinfo instead, pass that name as the third parameter to your model call:

var Test = mongoose.model('Test', testSchema, 'testinfo');
