When the optional file field is used, an error will be reported when there are empty files in the query set

Error is thrown from here https://github.com/django/django/blob/475cffd1d64c690cdad16ede4d5e81985738ceb4/django/db/models/fields/files.py#L40

I avoid it like this

from django.db.models.fields import files


class FieldFile(files.FieldFile):
    def _require_file(self):
        pass


class FileField(files.FileField):
    attr_class = FieldFile


class ImageFieldFile(files.ImageFieldFile):
    def _require_file(self):
        pass


class ImageField(files.ImageField):
    attr_class = ImageFieldFile

Is there a more elegant way?

A more elegant way:

from django.db.models.fields.files import FieldFile

FieldFile._require_file = lambda self: None  # type:ignore[attr-defined]
