Django queryset filter for blank FileField?
Question:
How do I perform a Django queryset filter looking for blank files in FileField fields?
The field isn’t null, it has a FileObject in it that doesn’t have a file.
Answers:
I was having this issue too, and finally found the solution!
no_files = MyModel.objects.filter(foo='')
This works because internally, the FileField is represented as a local file path in a CharField, and Django stores non-files as an empty string '' in the database.
An alternative solution:
no_files = MyModel.objects.filter(foo__in=['',None])
