Blog created with ExpressJS backed by MongoDB not showing posts from DB - mongodb

Question

I've created a very simple blog web app with ExpressJS and MongoDB. But the index page doesn't render the 'blogPosts' that I input into the DB. It only shows the title as "BL's Blog", without any posts below.
Why aren't the posts showing?
app.js:
//Module dependencies
var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
//Mongodb
var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/hello-express/');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
//GET
app.get('/', routes.index(db));
app.get('/users', user.list);
app.get('/userlist', routes.userlist(db));
app.get('/newuser', routes.newuser);
//POST
app.post('/adduser', routes.adduser(db));
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
routes/index.js(I only included exports.index as it's the relevant route to this problem):
exports.index = function(db) {
return function(req, res) {
var posts = db.get('blogPosts');
posts.find({}, {}, function(e, docs) {
res.render('index', {
"index": docs
});
});
};
};
views/index.jade:
extends layout
block content
h1.
BL's Blog
ul
- each post in index
li
h3 = post.title
p = post.content

Ok now I have actually found out the answer to my own question, thanks to the help of WiredPrairie.
The first problem lies with the name of the database that I'm using. Thus in my index.js, it should have been:
exports.index = function(db) {
return function(req, res) {
var posts = db.get('hello-express'); //Here's the difference.
posts.find({}, {}, function(e, docs) {
res.render('index', {
"index": docs
});
});
};
};
I listed in app.js that I'm using the database called 'hello-express' with this line below:
var db = monk('localhost:27017/hello-express/');
Hence the name of database being used should be named as 'hello-express'.
However, even after doing so, I could not render the Jade page properly. This was due to a syntax error (I know, I'm new.)
extends layout
block content
h1.
BL's Blog
ul
- each post in index
li
h3 #{post.title}
p #{post.content}
By using #{<var>} instead of =, the page was able to render properly. I still have no idea why this is the case, but at least it has solved my problem for now.
