저장하기 전에 이미지 크기를 조정하려고합니다.
from PIL import Image
class UserAvatarUpdate(views.APIView):
serializer_class = UserSerializer
def patch(self, *args, **kwargs):
instance = ExtUser.objects.get(id=self.request.user.id)
instance.avatar = self.request.FILES['file']
size = 100,100
filename = instance.avatar.path
image = Image.open(filename)
image = image.resize(size,Image.ANTIALIAS)
instance.avatar = image
instance.save()
return Response(
UserSerializer(instance).data,
status=status.HTTP_200_OK
)
하지만 저장시 아래 오류가 발생합니다.

내 모델 :
avatar = models.ImageField(
'Аватар',
blank=True,
null=True,
upload_to="user/avatar"
)
ImageField이와 같이 PIL 이미지를 직접 할당 할 수는 없습니다 . 약간의 해결 방법이 필요합니다.
from io import BytesIO
from django.core.files.base import ContentFile
image = Image.open(filename)
image = image.resize(size,Image.ANTIALIAS)
image_io = BytesIO()
image.save(image_io, format='jpeg', quality=80) # you can change format and quality
# save to model
image_name = "my_image"
instance.avatar.save(image_name, ContentFile(image_io.getvalue()))
