这是我为克服此问题所做的一些代码。尽管凯文·布朗的回答可能行得通，但我发现我的代码有点“轻松”的方法：
@detail_route(
methods=['post', 'put', 'patch', 'get'], permission_classes=[AllowAny],
authentication_classes=[NoAuthentication], serializer_class=MultimediaSerializer,
parser_classes=(FormParser, MultiPartParser,)
)
def upload_avatar(self, request, pk=None):
# Because we are using nested resources this was the only way i found to
# upload a file. Maybe there is a better way
if request.method in ['PATCH', 'POST']:
avatar = request.FILES.get('avatar')
if not avatar:
return Response(status=404)
try:
woman = WomenNativePassport.objects.get(pk=pk)
except WomenNativePassport.DoesNotExist:
return Response(status=404)
else:
request.FILES['thumbnail'] = request.FILES['avatar']
serializer = AvatarSerializer(
data=request.DATA, files=request.FILES
)
if serializer.is_valid():
woman.avatar.thumbnail.save(str(avatar), File(avatar))
return Response(status=204)
else:
return Response(status=404)
else:
multimedia = Multimedia.objects.filter(user_profiles_avatares__pk=pk)
page = self.paginate_queryset(multimedia)
serializer = self.get_pagination_serializer(page)
return Response(serializer.data)
# serializer
class AvatarSerializer(serializers.Serializer):
thumbnail = serializers.ImageField()
