Mongodb db.get('usercollection') not working corretly - node.js

Question

Issue is that db is not working properly
app.js
var express = require('express');
var path = require('path');
var http = require('http');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/nodetest1');
var routes = require('./routes');
var users = require('./routes/users');
var app = express.createServer();
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
app.use(function(req,res,next){
req.db = db;
next();
});
routes/index.js
exports.index = function(req, res){
var db = req.db;
var collection = db.get('usercollection');
collection.find({},{},function(e,docs){
res.render('userlist', {
"userlist" : docs
});
});
};
When I run userlist I get an error on line db.get('usercollection'). When I log req.db it is undefined.
How to resolve it?

Answer 1

you can directly use your db module in the index.js file
module.exports = (function() {
'use strict';
var apiRoutes = express.Router();
var Server = mongo.Server;
var Db = mongo.Db;
var BSON = mongo.BSONPure;
function connexionDataBase(callback){
var server = new Server('your db URL', 27017, {auto_reconnect: true});
db = new Db('you Db', server);
db.open(function(err, db) {
if(!err) {
console.log("Connected to 'you Db' database");
callback(err,db);
}
else{
console.log("not Connected to 'you Db' database");
callback(err,db);
}
});
})();
and in your app.js your can redirect the app routes to index.js :
var express = require('express');
var index = require('./index');
var app = express();
app.use('/index',index);
