下記のコードを使用して、画像をアップロードし、データベースコレクション内の画像のURLを更新しようとしています。ここでTypeError：タスクが非同期の関数ではありませんjs parrallel
Controller.prototype.handle = function (req, res, next) {
var id = req.params.id,
controller = req.params.controller,
optionalController;
optionalController = _.clone(controller);
// handle optional controller
if (controller === 'newboat') {
controller = 'boat';
} else if (controller === 'newcrew') {
controller = 'crew';
}
var files = req.files.files || {},
monthYear = new Date(),
monthYear = [monthYear.getFullYear(), monthYear.getMonth()],
filename = files[0].originalFilename,
path = files[0].path,
extension = filename.match(EXPRESSION_EXTENSION)[1],
destFolder = [ROOT, monthYear[0], '/', monthYear[1] ].join(''),
destination = [ROOT, monthYear[0], '/', monthYear[1] ,'/', id, '.', extension ].join('');
// log info
//console.log(id, controller, filename, extension, destination, path);
var opts = JSON.stringify({id: id, photo: ['/uploads/',monthYear[0], '/', monthYear[1] ,'/', id, '.', extension ].join('') });
async.series([
uploadImage(path,destFolder,destination),
ProcessUpload(optionalController, opts, res)
]);
};
// write file
var uploadImage = function(path,destFolder, destination) {
// The land of callbacks ------>>>>>> inception within inception
mkdirp(destFolder,777,function (err) {
fs.readFile(path, function (err, data) {
fs.writeFile(destination, data, function (err) {
if (err) {
console.log('image not uploaded..');
return false;
}else {
return true;
}
});
});
});
};
var ProcessUpload = function(optionalController, opts, res) {
opts = JSON.parse(opts);
if (optionalController === 'boat') {
updateBoatDatabase(opts);
}
};
/**
* Update boat photo to database
*/
var updateBoatDatabase = function (opts, callback) {
// save to database
return dbServices.dbBoat.updatePhoto(opts, callback);
};
が
/**
* Update image
*/
updatePhoto: function (opts, callback) {
var id = opts.id;
// find boat by id
this.modelClass.findById(id, function (err, model) {
if (err || !model)
return callback(err);
// set update value
model.photo = opts.photo;
// save
model.save(callback);
});
},
と呼ばれているデータベースサービスである私は、画像をアップロードするには、次のエラーを取得しますが、画像がサーバーにアップロードされますと、そのURLが同様にデータベースコレクションに更新します。私はそれが私のコールバックと関係があると仮定しているが、私はどこが間違っているのか本当にわからない。これをデバッグする方法についてのヒントをいただければ幸いです。
