Comment (by Sultan):
Why not implement this with the `Model.validate_unique()` method? It was
created precisely for this. It is already using resources for connecting
to the database and checking that there is no duplication.
I think that before `Model.validate_unique()` is called, we need first to
prepare the final `file.name` value by calling the
`FileFIeld.generate_filename()` method. The most appropriate place to do
this is in the `FileDescriptor.__set__` method, rather than in the
`FieldFile.save()` method, which I prefer, so that it always only accepts
the final filename.
