AJAX POST request never completes. Data posts to server - ajax

Question

I am sending a post request via AJAX. The data successfully posts but the AJAX call never completes. Backbone on the front; Node on the back. I am including the save function from my backbone view and the express route.
save: function(event) {
event.preventDefault();
console.log( 'You signed up for ' + this.model.get('name'));
var name = this.model.get('name');
var courseDay = this.model.get('courseDay');
var time = this.model.get('time');
var location = this.model.get('location');
jQuery.post("/test/signups", {
"name" : name,
"courseDay" : courseDay,
"time" : time,
"location" : location,
}, function (data, textStatus, jqXHR) {
console.log("Post response:");
console.dir(data);
console.log(textStatus);
console.dir(jqXHR);
});
}
Route:
app.post('/test/signups', isLoggedIn, function (req, res){
User.findOne({'_id': req.user.id }, function(err, user) {
if (err)
return done(err);
if (user) {
user.signup.name = req.body.name;
user.signup.courseDay = req.body.courseDay;
user.signup.time = req.body.time;
user.signup.location = req.body.location;
user.signup.modified = req.body.modified;
user.update({$push: { "signup" :
{ name: user.signup.name,
courseDay: user.signup.courseDay,
time: user.signup.time,
location: user.signup.location,
modified: user.signup.modified
}
}},{safe:true, upsert:true},function(err){
if(err){
console.log(err);
} else {
console.log("Successfully added" + user.signup);
}
});
}
});
});

Your server side code needs to send a response. Try something like below. Note I try to cover all cases of an error, user not found, and user found.
app.post('/test/signups', isLoggedIn, function (req, res){
User.findOne({'_id': req.user.id }, function(err, user) {
if (err) {
return res.status(500).send(err);
}
if (user) {
user.signup.name = req.body.name;
user.signup.courseDay = req.body.courseDay;
user.signup.time = req.body.time;
user.signup.location = req.body.location;
user.signup.modified = req.body.modified;
user.update({$push: { "signup" :
{ name: user.signup.name,
courseDay: user.signup.courseDay,
time: user.signup.time,
location: user.signup.location,
modified: user.signup.modified
}
}},{safe:true, upsert:true},function(err){
if(err){
return res.status(500).send(err);
}
console.log("Successfully added" + user.signup);
res.send(user);
});
} else {
res.status(404).send();
}
});
});
