Test fails with `django.db.utils.IntegrityError`

My test case gives me following error.

django.db.utils.IntegrityError: insert or update on table "django_admin_log" violates foreign key constraint "django_admin_log_user_id_c564eba6_fk_auth_user_id" DETAIL: Key (user_id)=(1) is not present in table "auth_user".

In my view class I have a log entry, during the test request.user.id is always None. so it use anonymous_user which is id = 1. (If I commented out the LogEntry.objects.log_action(), the test pass)

My view class:

class MyView(CreateAPIView):
    # For admin LogEntry
    anonymous_user_id = get_anonymous_user_id()

    def post(self, request, *args, **kwargs):
        """
        ...
        """

        LogEntry.objects.log_action(
            user_id=request.user.id or self.anonymous_user_id,
            content_type_id=self.content_type_id,
            object_id=target.id,
            object_repr=str(target),
            action_flag=ADDITION,
            change_message='message',
        )

        return Response({}, status=status.HTTP_200_OK)

My test:

def test_myview_append_api_works(self):

    def myview_append(url, p1, p2):
        resp = None
        resp = self.client.post(url, data={'paraphrase': p1, 'data_id': p2})
        return resp

    url = reverse('api-my_data:paraphrase_append')
    current_qa = Qa.objects.all()[0]  # get current existing qa = the qa created in the setUp

    p1 = 'test paraphrase'
    p2 = target.id
    resp = myview_append(url, p1, p2)
    self.assertEqual(resp.status_code, status.HTTP_200_OK)

I Tried using request_factory to set user in request but it didn't work

        request = self.request_factory.post(url,  data={'paraphrase': p1, 'qa_id': p2})
        request.user = self.user

        resp = MyView.as_view()(request)

Can any one help me with this test.
