Django DRF: ModelMixin Viewset: How to create a viewset to get user details and edit user details without passing id in url

Question

Suppose my user is logged in and he want to see the user details

I want to create an api end point like /userdetails/

Based on the user who logged in it should return back the details.

This is my serializer

class UserDetailsSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = [
            "id",
            "email",
            "first_name",
            "last_name",
            "is_staff",
            "is_active",
            "date_joined",
            "last_login",
            "modified_date",
            "creation_date",
        ]
        read_only_fields = [
            "email",
            "is_staff",
            "is_active",
            "is_superuser",
            "date_joined",
            "last_login",
        ]

Now I want to create a viewset for read and edit

I want something like this

class UserDetailsViewSet(
    mixins.UpdateModelMixin,
    mixins.RetrieveModelMixin,
    viewsets.GenericViewSet,
):
    queryset = User.objects.all()
    serializer_class = UserDetailsSerializer

and

router.register(r"userdetail",UserDetailsViewSet )

But the problem with the above is I dont want urls like /userdetail/<pk> instead only /userdetail. Because the <pk> can be obtained from the request.user

solution

After checking some posts, what I want is something without lookup_field and later overwrite get_object. Something similar to RetrieveAPIView without lookup field?

question remaining how to avoid lookup_field I tried

class UserDetailsViewSet(
    mixins.UpdateModelMixin,
    mixins.RetrieveModelMixin,
    viewsets.GenericViewSet,
):
    queryset = User.objects.all()
    serializer_class = UserDetailsSerializer
    lookup_field = ''

but it give error

django.core.exceptions.ImproperlyConfigured: "^userdetail/(?P<>[^/.]+)/$" is not a valid regular expression: missing group name at position 18

Subclass UserDetailsViewSet from generics.RetrieveUpdateAPIView and override get_object

Example:

class UserDetailsViewSet(
    generics.RetrieveUpdateAPIView
):
    queryset = User.objects.all()
    serializer_class = UserDetailsSerializer

    def get_object(self):
        queryset = self.filter_queryset(self.get_queryset())
        obj = get_object_or_404(queryset, pk=self.request.user.id)
        self.check_object_permissions(self.request, obj)
        return obj

register the view outside the drf router.

urlpatterns = [
    ...
    path('userdetail/', views.UserDetailsViewSet.as_view(),)
    ...
]
