301 != 200문제 조치 방법

def test_post_detail(self):
    Post_000 = Post.objects.create(
        title='The Firt Step',
        content='Hello, World!',
        created=timezone.now(),
        author=self.author_000
    )

    self.assertGreater(Post.objects.count(), 0)
    post_000_url = Post_000.get_absolute_url()
    self.assertEqual(post_000_url, '/blog/{}'.format(Post_000.pk))

    response = self.client.get(post_000_url)
    print(response)
    self.assertEqual(response.status_code, 200)

    soup = BeautifulSoup(response.content, 'html.parser')
    title = soup.title

    self.check_navbar(soup)

똑같이 따라쳤는데 301 != 200 에러가 고쳐지질 않습니다..

구글에 쳐보니 리디렉션? 문제인 것 같은데, 조치 방법을 잘 모르겠습니다. ㅠㅠ
