Moving the rename logic to _pre_save() would be the best way of doing things but I have a problem where I rename the uploaded file into one based on it's primary key. While in _pre_save(), self.id is None, so is there a way to access the value that will become the primary key?
Well, I never (yet) run in this kind of a problem. Generally I always use some kind of SlugField as a secondary primary key (unique) that gives me a pretty (and human readable) URLs. It's not possible to know under witch id record will be saved.
You can try to move rename logic into _post_save(). IIRC when you hit _post_save object is already in db so self.id will have a value. After renaming file and updating image field you must again save() object.
