You make the very rookie mistake of not calling close
/ closing the file (ZipFile
here) after opening it, best use the ZipFile
as a context manager:
def generate_images_zip(self) -> bytes:
content = BytesIO()
with ZipFile(content, 'w') as zipObj:
for image_fieldname in self.images_fieldnames():
image = getattr(self, image_fieldname)
if image:
zipObj.writestr(image.name, image.read())
return content.getvalue()
