Django 문제가 발생했습니다. URL : NoReverseMatch at/

Question

내 django 블로그 앱 프로젝트에서 slugified URL을 사용하여 페이지에 액세스하려고합니다.

이

문제 템플릿 코드는 모습입니다 :

  {% for post in latest_post_list %} 
    <li><a href="{% url 'blog:view_post' post.title_text|slugify %}">{{post.title_text}}</a>&nbsp;{{post.pub_date}}</li> 

이 내 URL 경로가 모습입니다 같은 :

url(r'^(?P<post_name>)/$', views.view_post, name='view_post')) 

이 내보기 기능이 모습입니다 같은 :

def view_post(request, post_name): 
pdb.set_trace() 
try: 
    post_name = post_name.encode('ascii','ignore') #un-unicode name 

    unslugified_post_name = post_name.replace('-', ' ') #will get slugified name, replace all hyphens with spaces 
    post = Post.objects.get(title_text=unslugified_post_name) 


except Post.DoesNotExist: 
    raise Http404("Post does not exist") 

return render(request, 'blog/posts.djhtml', {'post': post}) 

그리고 이것은받은 오류에 대한 스택 추적입니다.

이 오류를 일으키는 필드의 값은

내가 문제가 경로 정규 표현식에 아마 알고있다 "로렘 입숨"입니다,하지만 난 그것을 위해 적절한 정규 표현식을 알아내는 데 문제가 , 나는 그들에게 새로운 사람이다. 내가 지금하고있는 일은 그것이 어떻게 생겼는지에 관계없이 전달 된 문자열을 얻는 것뿐입니다. 그러나 당신이 저에게 더 튼튼한 것을 보여주고 싶다면, 나는 매우 감사 할 것입니다.

또한, slugify가 유니 코드 문자열을 반환하지 못하도록하는 방법이 있습니까?

Answer 1

view_post에 대한 귀하의 정규식은 비어 있습니다.

url(r'^(?P<post_name>[\w-]+)/$', views.view_post, name='view_post')
