Django NoReverseMatch [英] Django NoReverseMatch

问题描述

我不明白有什么问题吗？我试图制作一个项目的详细页面，例如 http：// tutorial。 djangogirls.org/en/extend_your_application/index.html
它在我的项目中不起作用，但在练习中，一切都很好。

错误讯息： NoReverseMatch at /

 反向'events.views.event_detail'与参数'（）'和关键字参数'{u'pk'：3}'未找到。 1个模式尝试：['$ event /（？P< pk> [0-9] +）/ $'] 
  

HTML（片段）

 < div class =col -xs-6>< a class =btn btn-primaryhref ={％url'events.views.event_detail'pk = event.pk％}>阅读更多< / a>< / DIV> 
< / div> 
  

settings.py

  ROOT_URLCONF ='mysite.urls'
  

app urls.py

  from django.conf.urls import include，url 
 from。导入视图
 
 urlpatterns = [
 url（r'^ $'，views.events_list），
 url（r'^ event /（？P< pk> [0- 9] +）/ $'，views.event_detail），
] 
  

app view.py

  from django.shortcuts import render，get_object_or_404 
 from django.utils import timezone 
 from .models import Event 
 
 def events_list（request）：
 events = Event.objects.filter（published_date__lte = timezone.now（））。order_by（'published_date'） 
 return render（request，'events / events_list.html'，{'events'：events}）
 
 def event_detail（request，pk）：
 event = Event.objects .get（pk = pk）
 return render（request，'events / event_detail.html'，{'event'：event}）
  

解决方案

你没有显示你的mysite.urls，但是从错误消息看，你已经做了这样的事情：

 （r'^ events / $'，include（'events.urls'）），
  

你需要删除终止$因为这意味着正则表达式的结束;没有什么可以匹配之后。它应该是：

 （r'^ events /'，include（'events.urls'）），
  

请注意，您还应该提供事件URL名称，以便更容易参考：

  url（r'^ $'，views.events_list，name ='events_list'），
 url（r'^ event /（？P< ; pk> [0-9] +）/ $'，views.event_detail，name ='event_detail'），
  

，以便您现在可以执行以下操作：

  {％url'event_detail'pk = event.pk％} 
  

I can't understand what's wrong? I tried to make a detail page of one item, like in example on http://tutorial.djangogirls.org/en/extend_your_application/index.html and It doesn't work in my project, but In exercises everything was good.

Error message: NoReverseMatch at /

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

HTML(fragment)

<div class="col-xs-6"><a class="btn btn-primary" href="{% url 'events.views.event_detail' pk=event.pk %}">Read more</a></div>
         </div>

settings.py

ROOT_URLCONF = 'mysite.urls' 

app urls.py

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

urlpatterns = [
    url(r'^$', views.events_list),
    url(r'^event/(?P<pk>[0-9]+)/$', views.event_detail),
]

app views.py

from django.shortcuts import render, get_object_or_404
from django.utils import timezone
from .models import Event

def events_list(request):
    events = Event.objects.filter(published_date__lte=timezone.now()).order_by('published_date')
    return render(request, 'events/events_list.html', {'events': events})

def event_detail(request, pk):
    event = Event.objects.get(pk=pk)
    return render(request, 'events/event_detail.html', {'event': event})

解决方案

You haven't shown your mysite.urls, but from the error message it looks like you have done something like this:

(r'^events/$', include('events.urls')),

You need to drop the terminating $, since that means the end of the regex; nothing can match after that. It should be:

(r'^events/', include('events.urls')),

Note that you should also give your event URLs names, to make it easier to reference:

url(r'^$', views.events_list, name='events_list'),
url(r'^event/(?P<pk>[0-9]+)/$', views.event_detail, name='event_detail'),

so that you can now do:

{% url 'event_detail' pk=event.pk %}
