我认为NoReverseMatch at /books/ Reverse for 'urlvar' not found. 'urlvar' is not a valid view function or pattern name.标签在books / index.html中无法正常工作但是我不知道该怎么解决。

这是我的代码：

books / urls.py

{% with %}

templates / books / index.html

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

urlpatterns = [
url(r'^$', views.BooksModelView.as_view(), name='index'),

url(r'^book/$', views.BookList.as_view(), name='book_list'),
url(r'^author/$', views.AuthorList.as_view(), name='author_list'),
url(r'^publisher/$', views.PublisherList.as_view(), name='publisher_list'),

url(r'^book/(?P<pk>\d+)/$', views.BookDetail.as_view(), name='book_detail'),
url(r'^author/(?P<pk>\d+)/$', views.AuthorDetail.as_view(), name='author_detail'),
url(r'^publisher/(?P<pk>\d+)/$', views.PublisherDetail.as_view(), name='publisher_detail'),
               ]

urlvar是一个变量，因此您在urlvar标记中使用{% url %}而不是字符串'urlvar'。

<li><a href="{% url urlvar %}">{{ modelname }}</a></li>

如果愿意，可以在标记中构造URL模式名称，或者如果发现可读性更高，则保留with标记。

<li><a href="{% url 'books:'|add:modelname|lower|add:'_list' %}">{{ modelname }}</a></li>

由于在反向访问URL时使用的是'books:名称空间，因此应在books/urls.py文件中设置app_name。

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

app_name = 'books'

urlpatterns = [
    ...
]

使用with标记设置URL模式名称时使用NoReverseMatch
