common type to compose closure objects. You can’t use the type because it’s unspeci�ed. 118namespace detail { template concept can_construct_all_pairs_view = requires(T&& t) { all_pairs_view{ } // namespace detail inline constexpr detail::all_pairs_fn all_pairs; 1 2 3 4 5 6 7 8 9 std::ranges::_Pipe::_Base 10 11 12 13 14 15 16 17 18 19 20 119namespace detail { template (rng) }; } }; } // namespace detail inline constexpr detail::all_pairs_fn all_pairs; 1 2 3 4 5 6 7 8 9 std::ranges::_Pipe::_Base

views.month_archive), 10. url(r'^articles/([0-9]{4})/([0-9]{2})/([0-9]+)/$', views.article_detail), 11. ] 上面的代码将 URL 的正则表达式映射到 views 里的回调函数。正则表达式通过括号来提取 URL 中的参数值。当一个用户请求页面时，Django 会顺序遍历这些匹配模式，直至模式和请求的 达式匹配到的 那些参数值。 比如，如果用户请求了“/articles/2005/05/39323/”这样的 URL，Django 就会这样调用函 数：news.views.article_detail(request, ‘2005’, ‘05’, ‘39323’)。 视图函数的执行结果只可能有两种：返回一个包含请求页面内容的 HttpResponse 对象；或者是抛 出 Http404 以获取更多 内容。 现在让我们添加更多的视图进 polls/view.py，这些视图都有点不一样，因为它们都接受一个参 数： 1. # polls/views.py 2. 3. def detail(request, question_id): 4. return HttpResponse("You're looking at question %s." % question_id)

创建表单 CHAPTER 3 页面操作 如果要在表单提交后将用户重定向到另一个页面，则可以在窗体的 on_submit 回调中返回页面操作： def on_detail(): return NavigateTo('/detail') AdminUI 支持 NavigateTo 和 Notification 作为页面操作： class adminui.NavigateTo(url=’/’) on_click=on_change_content), Button('Change Element', on_click=on_change_self), ]), Card(id='detail_card'), Card('Paragraph Card', [ Paragraph('This is the original content', id='paragraph') ]) The following code changes the content value of “detail_card”element when the users click the “Change Content”button.: return UpdateElement('detail_card', content=[ DetailGroup('Refund Request', content=[
