Question

错误：

NoReverseMatch at /

    Reverse for 'detail' with arguments '(3,)' and keyword arguments '{}' not found. 1 pattern(s) tried: [u'$(?P<college_id>[0-9]+)/$']

错误在这一行：

<li><a href="{% url 'app:detail' college.id %}">{{ college.college_name }}</a></li>

这是整个模板（index.html）：

{% if latest_college_list %}

<ul>
    {% for college in latest_college_list %}
    <li><a href="{% url 'app:detail' college.id %}">{{ college.college_name }}</a></li>
    {% endfor %}
</ul>

{% else %}
<p> No colleges available </p>
{% endif %}

观点：

from django.shortcuts import get_object_or_404, render
from .models import College

# Create your views here.
def index(request):
    latest_college_list = College.objects.order_by('college_name')
    context = {'latest_college_list': latest_college_list}
    return render(request, 'app/index.html', context)

def detail(request, college_id):
    college = get_object_or_404(College, pk=college_id)
    return render(request, 'app/detail.html', {'college':college})

urls.py：

from django.conf.urls import url
from . import views

app_name = "app"
urlpatterns = [
    # campusarchitecture.com/
    url(r'^$', views.index, name="index"),
    # /college_name
    url(r'^(?P<college_id>[0-9]+)/$', views.detail, name="detail")
]

root urls conf：

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

urlpatterns = [
    url(r'^$', include('app.urls')),
    url(r'^login/$', include('login.urls')),
    url(r'^admin/', admin.site.urls),
]

任何人都知道问题是什么？

Answer 1

问题在于：

url(r'^$', include('app.urls')),

应该是

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

请注意$应该被删除，因为它表示正则表达式模式的结束，并且它不会发现包含的网址模式。

其次，您需要在namespace中明确指定include。有关详情，请参阅documentation here。

同样，在$网址格式匹配后删除login/。
