blog / urls.py

urlpatterns = [
      -- skip --

      # Example: /2018/nov/
      url(r'^(?P<year>\d{4})/$', PostYAV.as_view(), name='post_year_archive'),

      -- skip --
]

blog / views.py

from blog.models import Post
from django.views.generic.dates import --skip--, YearArchiveView, --skip--

-- skip --

class PostYAV(YearArchiveView):
     model = Post
     date_field = 'modify_date'
     make_object_list = True

如果您尝试使用此网址：

 url(r'^(?P<year>\d{4})/$', PostYAV.as_view(), name='post_year_archive'),

然后从“模板”中这样调用它：

{% url 'blog:post_year_archive' year|date:'Y' %}

视图应该是这样的：

class PostYAV(YearArchiveView):
    model = Post
    date_field = 'modify_date'
    make_object_list = True

    def get(self, request, year, *args, **kwargs):
        post = Post.objects.filter(created__year=year)  # assuming created= models.DateField() or similar

但是如果您还有月份（例如与问题共享的图片，请尝试执行此操作）

url(r'^(?P<year>\d{4})/(?P<month>\d{2})/$', PostYAV.as_view(), name='post_year_archive'),

模板：

  {% url 'blog:post_year_archive' year|date:'Y' month|date:'m' %}

查看：

class PostYAV(YearArchiveView):
    model = Post
    date_field = 'modify_date'
    make_object_list = True

    def get(self, request, year, month, *args, **kwargs):
        post = Post.objects.filter(created__year=year, created__month=month)  # assuming created= models.DateField() or similar

发生您的问题中的错误，因为url正则表达式与从模板传递的参数不匹配。 %b显示的是本地化月份，与正则表达式[a-z]{3}不匹配。因此，%m会以月份作为数字传递，我们已经更新了月份的正则表达式以捕获模板发送的数字。
