serialization - How to pass request object to serializer in django rest framework unit test

Question

#model.py file
class FileModel(models.Model):
    file = models.FileField(verbose_name=_('File'))
    title = models.CharField(max_length=255, verbose_name=_('Title'))
    start_time_to_creating = models.DateTimeField(verbose_name=_('Start Time To Creating'))
    created_time = models.DateTimeField(auto_now_add=True, verbose_name=_('Created Time'))
    time_to_deleting = models.DateTimeField(null=True, blank=True, verbose_name=_('when_it_will_be_deleted'))
    page_count = models.PositiveIntegerField(null=True, blank=True, verbose_name=_('Page Count'))
    row_count = models.PositiveIntegerField(null=True, blank=True, verbose_name=_('Row Count'))
    user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, verbose_name=_('User'))

#serializers.py file
class FileSerializer(serializers.ModelSerializer):
    class Meta:
        model = FileModel
        fields = ['id', 'file', 'title', 'start_time_to_creating', 'created_time', 'time_to_deleting', 'page_count',
                  'row_count']

#views.py file
class FileListByUserView(generics.ListAPIView):
    queryset = FileModel.objects.all()
    serializer_class = FileSerializer
    filter_backends = (DjangoFilterBackend, OrderingFilter)
    filterset_class = FileFilter
    ordering_fields = ['created_time', 'title']
    ordering = ['-created_time']

    def get_queryset(self):
        user_id = self.kwargs.get('user_id')
        return super().get_queryset().filter(user=user_id)

#urls.py file
urlpatterns = [
    url(r'^list/(?P<user_id>[0-9]+)/?$', FileListByUserView.as_view(), name='file-list-by-user')
]

I serialize my FileModel model with FileSerializer and get it as a response. I want to test this. but I could not give the request object to the FileSerializer serializer that I used in unit test. So the file url does not match the data in the response because I cannot make the absolute url and it falls into error.

from rest_framework.test import APIClient

class TestBase(TransactionTestCase):
    reset_sequences = True

    def setUp(self):
        super().setUp()
        self.client = APIClient()

    def test_list_by_user(self):
        
        response = self.client.get(reverse('file-list-by-user', kwargs={'user_id': 1}))
        self.assertEqual(response.status_code, 200)


        file_models = FileModel.objects.all()
        file_serializer_data = FileSerializer(instance=file_models, many=True, context={'request': }).data

        content = str(response.content, encoding="utf8")
        content_json = json.loads(content)

        self.assertEqual(file_serializer_data, content_json)
