NoReverseMatch at / Reverse for 'post' not found. 'post' is not a valid view function or pattern name, как исправить?

Question

[None]

В django не первый день, но добавил get_absolute_url и абсолютно не понимаю что не так!
models

class Post(models.Model):
    title = models.CharField(max_length=255)
    body = models.TextField(max_length=500)
    created_time = models.DateTimeField(auto_now=True)

    def get_absolute_url(self):
        return reverse('post', kwargs={'post_pk': self.pk})

urls

path('post/<int:post_pk>/', post_detail, name='post_detail'),

шаблон

{% for j in post %}
{{j.id}}
{{j.title}}<br>
{{j.body}}<br>
{{j.created_time}}
<a href="{{j.get_absolute_url}}">Подробнее</a>
<hr>
{%endfor%}

ошибка

здесь у тебя post

return reverse('post', kwargs={'post_pk': self.pk})

здесь уже post_detail

path('post/<int:post_pk>/', post_detail, name='post_detail'),
