javascript - Mongoose model data not saved -

i working on nodejs project, using mongoose , mongodb, , when handling profile update logic, try post data server including profile photo upload, use formidable handle file upload , there no issue, other form fields not being saved there no error message, below it's route code, please me goes wrong.

 router.post('/api/profileupdate/:username', function(req, res, next) {   user.findone({     username: req.params.username     }, function(err, user) {         if (err) {             console.log(err);          } else {             if (user) {                 console.log('user found, going update ...');                 user.age = req.body.age;                 user.gender = req.body.gender;                 user.description  = req.body.description;                 user.occupation = req.body.occupation;                  var form = new formidable.incomingform();                 form.parse(req, function(err, fields, files) {                     //res.writehead(200, {'content-type': 'text/plain'});                     //res.write('received upload:\n\n');                     res.end(util.inspect({fields: fields, files: files}));                 });                  form.on('end', function(fields, files) {                     console.log(fields);                     console.log(req.body.age);                     console.log(files);                       if (this.openedfiles[0]) {                         /* temporary location of our uploaded file */                         var temp_path = this.openedfiles[0].path;                         /* file name of uploaded file */                         var file_name = this.openedfiles[0].name;                         /* location want copy uploaded file */                         var new_location = 'public/images/uploads/';                          fs.copy(temp_path, new_location + file_name, function(err) {                             if (err) {                             console.error(err);                           } else {                             user.profile_photo = '/images/uploads/' + file_name + '?dim=200';                             console.log(user.profile_photo);                             console.log("success!")                              // save data                             user.save(function(err) {                                 if (err){                                     console.log('error in saving user: '+err);                                       throw err;                                   }                                 console.log('user update succesful');                                 console.log(user.username);                                 console.log(user.profile_photo);                               });                           }                         });                     }                     else {                      }                  });                 res.redirect(req.url);              }         }  }); }); 

try other approach see if files , fields coming through:

var fields=[] var files = [] form.on('field', function(field, value) {   fields.push([field, value]); }) form.on('file', function(field, file) {   console.log(file.name);   files.push([field, file]); }) form.on('end', function() {   console.log('done');   console.log(files)   console.log(fields) });
