Django-taggit-templatetags2 属性错误

Question

我需要帮助，使用标签块作为包含该标签的所有帖子的链接。使用 Django-taggit-templatetags2。

'function'对象没有属性'filter'

tags.html

      <h2>Tags</h2>
      {% get_taglist as tags %}
      {% for tag in tags %}
      <h4><a href="{{tag}}">{{tag}} x{{tag.num_times}}</a></h4>
      {% endfor %}

urls.py

url(r'^blog/tags/(?P<slug>[a-z0-9]+)/$', views.TagDetailView.as_view(), name = 'tag'),

views.py

class TagDetailView(DetailView):
    template_name = 'home/tag.html'
    context_object_name = 'tag'

    def get_queryset(self):
        return Post.objects.all

追溯：

内部文件“/home/vinyasa/web_dev/practice/venv/lib/python3.5/site-packages/django/core/handlers/exception.py” 39. response = get_response(request)

_get_response 中的文件“/home/vinyasa/web_dev/practice/venv/lib/python3.5/site-packages/django/core/handlers/base.py” 187. response = self.process_exception_by_middleware(e, request)

_get_response 中的文件“/home/vinyasa/web_dev/practice/venv/lib/python3.5/site-packages/django/core/handlers/base.py” 185. response = Wrapped_callback(request, *callback_args, **callback_kwargs)

视图中的文件“/home/vinyasa/web_dev/practice/venv/lib/python3.5/site-packages/django/views/generic/base.py” 68. return self.dispatch(request, *args, **kwargs)

调度中的文件“/home/vinyasa/web_dev/practice/venv/lib/python3.5/site-packages/django/views/generic/base.py” 88. return handler(request, *args, **kwargs)

获取文件“/home/vinyasa/web_dev/practice/venv/lib/python3.5/site-packages/django/views/generic/detail.py” 115. self.object = self.get_object()

get_object 中的文件“/home/vinyasa/web_dev/practice/venv/lib/python3.5/site-packages/django/views/generic/detail.py” 43. queryset = queryset.filter(**{slug_field: slug})

异常类型：/blog/tags/mods/ 中的 AttributeError 异常值：'function' 对象没有属性 'filter'

你忘记了views.py中的一对括号：

class TagDetailView(DetailView):
    template_name = 'home/tag.html'
    context_object_name = 'tag'

    def get_queryset(self):
        return Post.objects.all()
