{% for c in categories %}
<li>
<a href="{{c.get_absolute_url}}" class="{% if current_category.slug == c.slug %}active{% endif %}">{{c.name}}</a>
</li>
{% endfor %}

을 이렇게 넣고... 서버 돌렸을 때 해당 페이지에서 계속 아래와 같이 뜹니다.

NoReverseMatch at /정보/학습후기/

Reverse for 'page_category' not found. 'page_category' is not a valid view function or pattern name.
이라고 뜹니다..ㅠ

오류가 발생한 부분은 보니 여기인데...
<a href="{{c.get_absolute_url}}" class="{% if current_category.slug == c.slug %}active{% endif %}">{{c.name}}</a>

설정 했고.. get_absolute_url부분에서 reverse 부분도 딱히 문제가 없는데.. 어디가 문제일까요??

admin에서 값은 넣었습니다! ㅠㅠ
