在网址格式中使用include（）时出现意外的NoReverseMatch错误 [英] Unexpected NoReverseMatch error when using include() in urls patterns

问题描述

在 index.html

未找到带有参数'（3，）'和关键字参数'{}'的'detail'。尝试了1个模式：['$（？P< pk> [0-9] +）/ $']

views.py

def rock_and_feat(request):
    feats = Feat.objects.order_by('-created')[:3]
    rocks = Rockinfo.objects.order_by('-rank')[:50]
    context = RequestContext(request, {
        'feats': feats, 'rocks': rocks
    })
    return render_to_response('template.html', context)


class DetailView(generic.DetailView):
    model = Feat
    template_name = 'feature/detail.html' 
    context_object_name = 'feat'

urls.py

urlpatterns = [
    url(r'^$', views.rock_and_feat, name='rock_and_feat'),
    url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),
]

index.html >

{% extends "index.html" %}
{% block mainmast %}
<div id="wrapper">
{% if feats %}
{% for feat in feats %}
 <div class="specialsticky">
 <a href="{% url 'feature:detail' feat.id %}"><img src="{{ feat.image.url }}" alt="some text"></a>
  <h1 class="mast-header">
    <a href="#">{{feat.title}}</a>
  </h1>
 </div>

 {% endfor %}
 {% else %}
<p>No </p>
 {% endif %}
</div>
{% endblock %}

detail.html

{% extends "index.html" %}

<iframe width="560" height="345" src="{{ feat.youtube_link }}"       frameborder="0" allowfullscreen></iframe>

项目 urls.py

project urls.py

from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static


urlpatterns = [
    url(r'^$', include('feature.urls', namespace="feature")),
    url(r'^admin/', include(admin.site.urls)),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

在添加<在 index.html 中图像上的href = 。

the app worked fine before I added the <a href= on the image in index.html.

推荐答案

这表明问题所在。

'$(?P<pk>[0-9]+)/$'

在模式的开头不应有美​​元符号（与字符串的末尾匹配）。

There shouldn't be a dollar sign (which matches the end of the string) at the beginning of the pattern.

问题是由方式ou包括urls.py。您当前在正则表达式中有一个美元：

The problem is caused by the way you are including the urls.py. You currently have a dollar in the regex:

url(r'^$', include('feature.urls', namespace="feature")),

要解决此问题，请从正则表达式中删除美元。

To fix the problem, remove the dollar from the regex.

url(r'^', include('feature.urls', namespace="feature")),
