我正在开发一个简单的宠物商店应用程序

我几次遇到这个错误,我设法理解它并修复它,但在这种情况下。我不知道出了什么问题。一切对我来说似乎都很清楚。

它说我的 store.html 在 {% url world:brazil animal.id %} 的位置有一个错误,但我已经定义了命名空间。

  Reverse for 'brazil' with arguments '('',)' and keyword arguments '{}' not found.
  Error during template rendering

  In template C:\djcode\mysite\pet\templates\store.html, error at line 5
  Reverse for 'brazil' with arguments '('',)' and keyword arguments '{}' not found.
  1     Sydney's Pet Store
  2     {% if store %}
  3     <ul>
  4     {% for a in store %}
  5     <li><a href ="{% url world:brazil animal.id %}">{{ a.name }}</li>
  6     {% endfor %}
  7     
  8     </ul>
  9     {% endif %}

我的商店.html

Sydney's Pet Store
{% if store %}
<ul>
        {% for a in store %}
    <li><a href ="{% url world:brazil animal.id %}">{{ a.name }}</li>
    {% endfor %}

</ul>
{% endif %}

我的观点.py

 from pet.models import Store , Pet
 from django.shortcuts import render_to_response ,get_object_or_404

 def index(request):
     store = Store.objects.all()
     return render_to_response ('store.html',{'store':store})

 def brazil(request , animal_id):
     store = get_object_or_404(Store , Pet, pk=animal_id)
     return render_to_response ('animal.html',{'store':store})

我的宠物应用 URLCONF:

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

 urlpatterns = patterns ('pet.views',
     url(r'^$','index',name = 'index'),
     url(r'^(?P<poll_id>\d+)/$','brazil',name ='brazil'),

     )

我的主要URCONF:

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

  admin.autodiscover()
  urlpatterns = patterns('',

      url(r'^pet/',include('pet.urls' , namespace='world' )),

  ) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

  urlpatterns += staticfiles_urlpatterns()

因为你没有定义animal.id。您在视图中呈现的只是存储变量。

Sydney's Pet Store
{% if store %}
<ul>
        {% for a in store %}
    <li><a href ="{% url world:brazil a.id %}">{{ a.name }}</li>
    {% endfor %}

</ul>
{% endif %}
