猫鼬模型数据未保存

问题描述：

我正在使用mongoose和mongodb开发一个nodejs项目，并且在处理配置文件更新逻辑时，我尝试将一些数据(包括配置文件照片上传)发布到服务器，我使用强大的功能来处理文件上传，并且没问题，但是即使没有任何错误消息也没有保存我的其他表单字段，下面是路由代码，请帮助我哪里出错了.

I am working on a nodejs project, using mongoose and mongodb, and when handling a profile update logic, I try to post some data to the server including a profile photo upload, I use formidable to handle the file upload and there is no issue, but my other form fields not being saved even there is no any error message, below it's the route code, please help me where 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 to 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;
                        /* The file name of the uploaded file */
                        var file_name = this.openedFiles[0].name;
                        /* Location where we want to copy the 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 the 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);

            }
        }
 });
});

答

尝试使用另一种方法来查看文件和字段是否全部通过:

Try this other approach to see if the files and fields are all 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)
});
