OK, I have a model for TemporaryFile and the final file model (File) they have different storage functions (destinations). I'm saving the first model and after some time I need to pass the file to the second model, so that it saves the file its way. For now I'm doing something like that:
attachments.append(File(file=temp.file.file, message=self))
But it just passes over the URL. Which isn't what I'd like to see.
