  django 3.1.5 这样写
  path('detail/<int:article_id>/', blog.views.get_detail),

  参考https://docs.djangoproject.com/

  应该是版本不一样所以路由配置不一样把，你改改这个试试：
  

  就是把老师讲的那个<int:article_id>改成

  (?P<article_id>[0-9]+)

  具体和上图那样子。

  然后在views.py里面稍微改一下

  

  只有第41行的代码不一样，注意改一下，然后应该就可以了

  url(r'^detail/<int:article_id>$',views.get_detail_page)
  
  def get_detail_page(request,article_id):
      all_article = Article.objects.all()
      curr_article = None
      for article in all_article:
          if article.article_id == article_id:
              curr_article = article
              break
      #curr_article = Article.objects.all()[1]
      session_list = curr_article.content.split('\n')
      return render(request,'cs/detail.html',
                    {
                        'curr_article': curr_article,
                        'session_list':session_list
                    })

  Page not found (404)

  Request Method:	GET
  Request URL:	http://127.0.0.1:8000/play/detail/1

  Using the URLconf defined in project.urls, Django tried these URL patterns, in this order:

  1. ^play/ ^hello/$

  2. ^play/ ^content/$

  3. ^play/ ^index/$

  4. ^play/ ^detail/<int:article_id>$

  5. ^admin/

  The current path, play/detail/1, didn't match any of these.
