partial update in django rest viewset(not modelviewset) - django

Question

i am beginner in django and i was trying to learn work with djangorest viewset(not modelviewset)
and i cant find any resource to undrestand it.
i want to learn how to write a partial_update with viewset.
here is what i have tried:
models.py :
class UserIdentDocs(models.Model):
owner = models.ForeignKey(User,on_delete=models.CASCADE, related_name = "user_ident_Docs")
code = models.PositiveBigIntegerField(null=True)
img = models.ImageField(null=True)
video = models.FileField(null=True)
is_complete = models.BooleanField(default=False)
serializers.py:
class AdminUserIdentSerializer(serializers.ModelSerializer):
class Meta:
model = UserIdentDocs
fields = [
"owner",
"code",
"img",
"video",
"is_complete",
]
views.py:
from rest_framework.parsers import MultiPartParser, FormParser
class UserDocAdminViewSet(viewsets.ViewSet):
"""User docs admin view set"""
permission_classes = [AllowAny]
parser_classes = (MultiPartParser, FormParser)
serializer_class = AdminUserIdentSerializer
queryset = UserIdentDocs.objects.filter(is_complete=False)
def list(self, request):
serializer = self.serializer_class(self.queryset, many=True)
return Response(serializer.data)
def retrive(self, request, pk=None):
doc_object = get_object_or_404(self.queryset, pk=pk)
serializer = self.serializer_class(doc_object)
return Response(serializer.data)
def create(self, request ):
serializer = self.serializer_class(data=request.data)
serializer.is_valid(raise_exception=True)
serializer.save()
return Response(serializer.data,status=status.HTTP_201_CREATED)
def partial_update(self, request, pk=None):
doc_object = get_object_or_404(self.queryset, pk=pk)
serializer = self.serializer_class(doc_object,data=request.data)
serializer.is_valid(raise_exception=True)
serializer.save()
return Response({"detail":"item updated succesfuly"}, status=status.HTTP_205_RESET_CONTENT)
urls.py:
urlpatterns = [
...
# admin viewset for docs
# list of accounts with is_complete=False
path("admin/userdocs/", UserDocAdminViewSet.as_view({"get":"list", "post":"create"}), name="user-docs-list"),
path("admin/userdocs/<int:pk>", UserDocAdminViewSet.as_view({"get":"retrive","patch":"partial_update"}), name="user-docs-detail"),
]
i can create user in browsable api but when i want to use partial update i can't even see the fields in browsable api and i only see this :
media type: multipart/form-data
content:this is what i see
