FIxed #8613: removed vestigal `FileField.save_file()`. Thanks, kratorius.

            # Otherwise, just close the file, so it doesn't tie up resources.

            file.close()

    def save_file(self, new_data, new_object, original_object, change, rel,

                  save=True):

        upload_field_name = self.name + '_file'

        if new_data.get(upload_field_name, False):

            if rel:

                file = new_data[upload_field_name][0]

            else:

                file = new_data[upload_field_name]

            # Backwards-compatible support for files-as-dictionaries.

            # We don't need to raise a warning because the storage backend will

            # do so for us.

            try:

                filename = file.name

            except AttributeError:

                filename = file['filename']

            filename = self.get_filename(filename)

            getattr(new_object, self.attname).save(filename, file, save)

    def get_directory_name(self):

        return os.path.normpath(force_unicode(datetime.datetime.now().strftime(smart_str(self.upload_to))))
