I'm working on a webapp that requires atuhentication process and session management with express. I've done with the backend sessions stuff. Now i want to show on the UI the user who is signed in. privateContent is a function that verify if someone is logged in, Like so:
...
app.get( '/authRequired', queries.privateContent , routes.tasks );
...
Here is queries.privateContent:
...
exports.privateContent = function ( req, res, next ) {
if ( req.session.user ) {
var username = req.session.user.username;
User.findOne( { 'username': username }, function ( err, obj ) {
if ( true ) {
next();
} else {
res.redirect('/');
}
});
} else {
res.redirect('/');
}
};
...
What i want to know is: Am i able to send data like this? :
...
next( username );
...
if so, how can i retrieve it when routes.tasks render, if that happens as follows (i'm trying to get the data in the code below, but it does not work.):
...
exports.my_tasks = function ( req, res, data ) {
console.log(data);
res.render('tasks/tasks',
{ title: 'Paraíso', controller: 'MyTasksController', user: data });
};
...
As you can guess, my intentions are to pass via next the current user who is signed in to the routing modules, so i can print the username in the UI using jade. Thank you for your help. :)
In this case you have a few options (only use one of these!):
req
objectIn your exports.privateContent function, once a user is found in the database, you can simply add that data to the res.locals:
User.findOne( { 'username': username }, function ( err, obj ) {
if ( true ) {
// this variable will be available directly by the view
res.locals.user = obj;
// this will be added to the request object
req.user = obj;
next();
} else {
res.redirect('/');
}
});
Then in your exports.my_tasks route, res.locals.user
will be whatever obj was in the middleware. You can then simply access that in the view as the variable user
.
So, all together, you can access the data in your route in these ways:
exports.my_tasks = function ( req, res ) {
res.render('tasks/tasks', {
userFromReq: req.user, // this exists because you added in the middleware
userFromSession: req.session.user, // this was already in the session, so you can access
userFromRes: [DO NOT NEED TO DO THIS] // because res.locals are sent straight to the view (Jade).
});
};
