javascript - AngularJS + ng file upload + Sails JS

Question

I need to send so information together with each file I upload. The documentation says that I can achieve that with the data parameter but I cant access it from my action in my Sails controller.

Frontend:

Upload.upload({ url: '/file/upload', arrayKey: '', data: { file: $scope.files, otherInfo: {user: user, person: 12 }}}).....

Sails JS:

req.file('file').upload({ dirname: '../../websrc/uploads' }, function(err, files) {
      if (err) return res.serverError(err);
      return res.json({
        message: files.length + ' file(s) uploaded successfully!',
        files: files
      });
    });

If I log files, I see X objects like this:

UploadedFileMetadata[0]
extra: undefined
fd: "/xxxxxxxxxxxxxx/uploads/24fd1f66-36df-40ec-bed3-45e18df77469.jpg"
field: "file"
filename: "xxxxxxxxxxxxxxxxxxxxxx.jpg"
size: 199247
status: "bufferingOrWriting"
stream: PassThrough
type: "image/jpeg"

How can I send information for each one of my files and access it from my server?

 $scope.uploadFiles = function () {

            var request = {
                method: 'POST',
                url: '/api/fileupload/',
                data: formdata,
                headers: {
                    'Content-Type': undefined
                }
            };

            // SEND THE FILES.
            $http(request)
                .success(function (d) {
                    alert(d);
                })
                .error(function () {
                });
