How to redirect to view page using mongoDB and node.js

I am new with node.js, mongoDB and jade.

To redirect to userlist page I have following route in /routes/index.js

router.get('/userlist', function(req, res) {
    var db = req.db;
    var collection = db.get('usercollection');
    collection.find({},{},function(e,docs){
        res.render('userlist', {
            "userlist" : docs
        });
    });
});

This route redirects me to userlist page. There I display a list of all users. Here I have a link on each record to view details:

following is my userlist.jade

extends layout

    block content
        h1.
            User List
        ul
            each user, i in userlist
                li
                    a(href="/viewuser/id/#{user._id}")=user.username

This:

a(href="/viewuser/id/#{user._id}")=user.username

Gives me:

<a href="/viewuser/id/56aca898d9b0de79214ae381">Dhara</a>

Now I don't know what route should be there for view details on click of the link and how to get selected record data for view screen.

maybe you need to specify the view in your app server file

app.get('/userlist', function(req, res){ res.render('userlist', { title: 'Your_Title' }); });

I hope to be helpful!

I use a clear and distributed stack MEAN.js, with a yeoman constructor that will help you to build secure and good-practice programming applications.

This is the way I get a concrete user data. It´s a little more spread than your code but it´s clear.

Hope it helps!

routes.js

app.use('/api/users', require('./api/user'));

api/user/index.js

var controller = require('./user.controller');
router.get('users/:id', controller.show);

user.controller.js:

// Get a single user
exports.show = function(req, res) {
  User.findById(req.params.id, function (err, user) {
    if(err) { return handleError(res, err); }
    if(!user) { return res.send(404); }
    return res.json(user);
  });
};

then I´ll call for a user with an url like users/xxxxxx where xxxx is the user id. Then if you want to do it like /viewuser/id/xxxxxx you will need to change the route like this:

api/user/index.js

var controller = require('./user.controller');
router.get('viewuser/id/:id', controller.show);

user.controller.js:

// Get a single user
exports.show = function(req, res) {
  User.findById(req.params.id, function (err, user) {
    if(err) { return handleError(res, err); }
    if(!user) { return res.send(404); }
    return res.json(user);
  });
};
