python - Django 1.8 使用多个 DetailView

Question

我一直在尝试在我的 views.py 中使用多个 DetailView，但由于某种原因，我在模板渲染期间收到此错误。 http://prntscr.com/7f8vql http://prntscr.com/7f8vlv .

我的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'

class RockDetailView(generic.DetailView):
    model = Rockinfo
    template_name = 'feature/detailrock.html' 
    context_object_name = 'rockinfo'

我的应用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'),
url(r'^(?P<pk>[0-9]+)/$', views.RockDetailView.as_view(),  name='detailrock'),
]

我的项目的urls.py

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

template.html

   {% block rocker %}
      {% if rocks %}
          {% for item in rocks %}

              <div class="artist-container">
              <a href="{% url 'feature:detailrock' rockinfo.id %}"><img src="{{ item.rock_img.url }}" class="artist-img" alt="Dimitri Vegas &amp; Like Mike">
               <div class="artist-info">{{ item.rock_name }}</div></a></div>
           {% endfor %}
       {% else %}
               <p>No rockers are available.</p>
       {% endif %}
              </div></div>
   {% endblock %}

我不知道错误是什么。谢谢

我记得你关于rock_and_feat的问题。

有几件事我想提一下:

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

您没有rockinfo。它是item。在这一行中:

{% url 'feature:detailrock' item.id %}

还有一件事。请注意，id is not the same作为pk。

{% url 'feature:detailrock' item.pk %}

最后一件事。可以替换为:

   {% if rocks %}
      {% for item in rocks %}
          ....
      {% endfor %}
   {% else %}
       <p>No rockers are available.</p>
   {% endif %}

有了这个(docs):

   {% for item in rocks %}
       ...
   {% empty %}
       <p>No rockers are available.</p>
   {% endfor %}
