T点击页面的href="{% url 'detail' article.id %}"【http://127.0.0.1:8000/detail/2】
U通过url索引找到url(r'^detail/(?P<page_num>\d+)$', detail, name='detail'),
把detail后面的\d+数字传入并命名为page_num变量
V 传入page_num【即前端页面的article.id，在U层被命名为page_num】找到指定文章
def detail(request, page_num): article = Article.objects.get(id=page_num) context['article'] = article return render(request, 'article_detail.html', context)阅读全文
