I have to send data using socket.io.when a user enter his login and a password,he will be redirect to index.ejs and the username will be send to the server.
route.js (I mentioned only the part of the script not the hole script to show that when the login and password are correct a user get an index page and the userobject send to the index):
var index = function(req, res, next) {
if(!req.isAuthenticated()) {
res.redirect('/signin');
} else {
var user = req.user;
if(user !== undefined) {
user = user.toJSON();
}
res.render('index', {title: 'Home', user: user});
}
};
app.js:
io.sockets.on('connection', function (socket) {
socket.on("new_user",function(user1){
console.log("a new user is connected",user1);
var current_date=new Date();
var date=current_date.toString();
ex.user_connect(user1,date);
});
});
index.ejs:

NB:I got the username on the navbar but I don't get it on the server console.
Ejs render all template variables in server and then return plain html to the client , so
Inside your script , do you have variable global user initialized? :
var user1 = user.username // var user = {username:"foo":} ,something like that before.
If you trying to get user from template variable you could try:
var user1= "<%= user.username%>";
This will render <%= user.username%> inside script tag before send to the client ( browser)

So this is it.
Somewhy if I check MongoDB I only see empty objects with only an id, maybe I didn't submit it or my ejs is wrong? (I'm new to this)
Also if anyone knows how I can do something like, checking if since the previous date 10 minutes didn't pass then use those measurements?
Any help is welcome!
mongoose.connect('mongodb://localhost:27017/test');
const Cat = mongoose.model('Cat', { name: String });
const kitty = new Cat({ name: 'Zildjian' });
kitty.save().then(() => console.log('meow'));```
```.save()``` is returns a promise resolves with ```(err)```
check that

we have created a e-commerce project in that while clicking on categories in UI it will renders to category page in that page it has show one product of each subcategory
i have written the code in which the entire products with the specific category name is displaying how i can remove the extra products as of now i required only one product of each sub category of the particular category
the routing code is
router.get("/shop/:category_name", function(req, res){
//querystring
var url = require('url');
var url_parts = url.parse(req.url, true);
var query = url_parts.query;
var viewModel = {
breadCrumb: [],
categories : [],
featuredProducts :[],
products : [],
};
viewModel.breadCrumb.push({
name : 'Home',
class : 'breadcrumb-ordinary'
});
viewModel.breadCrumb.push({
name : req.params.category_name,
class : 'breadcrumb-active'
});
async.parallel({
categories: function(cb){
Category.find({}, cb);
},
categories1:function(cb){
Category.find({category_name:req.params.category_name}, cb);
}
}, function(err, results) {
if (err) throw err;
viewModel.categories1=results.categories1;
viewModel.categories=results.categories;

so i am posting a photo in which my output is there it contains all products of a specified category i need only one product from each sub category of the specified category and the image contains four products of protection category and two sub categories air freshners and Head unit , air freshners contains three products i need to display only one from airfreshner and one from head unit in which we need
In Your Router Code, Edit this section
categories1:function(cb){
Category.find({category_name:req.params.category_name}, cb);
}
Change the above to this
categories1:function(cb){
Category.findOne({category_name:req.params.category_name}, cb);
}
That should solve it for you.
Just like in the question: how can I use Passport without redirecting user to the /signin or /home when he fails his authentication?
To login user has to click on "login" button, a modal will pop up, he fills the data. If he succeeds he is redirected to the homepage. But if he isn't I want to show him the flash message in the same modal without redirecting. It kinda works because if you fail to login and click "login" again the error message will be shown. But I don't want to force users to constantly click it to check what went wrong.
They should fail, see the error, fill in new data and click submit again.
home.server.route.js:
var user = require(__dirroot + '/app/controllers/user.server.controller.js')
var passport = require('passport')
module.exports = function(app) {
var home = require(__dirroot + '/app/controllers/home.server.controller.js')
app.get('/', home.render)
app.route('/home/signin')
.get(user.renderSignin)
.post(passport.authenticate('local', {
successRedirect: '/',
failureRedirect: '/',
failureFlash: true
}))
}
home.server.controller.js:
exports.render = function(req, res) {
res.render('home', {
title: 'erpeg',
messages: req.flash('error') || req.flash('info'),
srvuser: req.user ? req.user : null,
cltuser: JSON.stringify(req.user)
})
}

PS: I had it working with separate pages but since I am changing my template engine from Jade to EJS I thought I will do it more elegantly (inside a modal). Any help?
