我已经构建了一个测试用例来演示访问多个 pk 值时 django url 和基于类的视图的问题。
演示问题的文件是addressbook/family/templates/family/family_detail.html，我已经注释掉了我尝试的行。
我想从家庭详细信息页面链接到特定的人，但第一次评论尝试给出了NoReverseMatch at /family/2/ . Reverse for 'person-detail' with arguments '(1,)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['family/(?P<pk>\\d+)/person/(?P<pk>\\d+)/$']
第二次和第三次评论的尝试在服务器上旋转了很长时间，然后最终给出error at /family/1/patient/1/
redefinition of group name 'pk' as group 2; was group 1
