Inserting an array in mongodb using mongoose in a schema where other fields are already added from user registration
This is logical because first you do a it on various user objects (req.user / new user):
**var newUser = new User();This will create a new User object, and then:
newUser.save(function (err, data) {This will save the newly created user into a new document. If you want to use the .save, rewrite it to (reused your own code):
User.findOne({ 'username' : username }, function(err, user) { // In case of any error, return using the done method if (err){ console.log('Error in SignUp: '+err); return done(err); } user.courseEnrolled = req.body.courseEnrolled; user.save(function (err, data) { if(err) throw err; else { console.log('course Updated'); } });
