Django urls.py 正则表达式

Question

我完成了 Django 初学者教程，我正在尝试完成 [The Django Book: Chapter 7 Forms][1]。我在使用文档中的方法将 URLSconf 链接到 search_forms.html 页面时遇到问题。很可能是因为我使用了单独的 'main' 和 'app' urls.py 文件

谁能帮我确定正确的 URLconf 格式？我想在访问http://127.0.0.1:8000/polls/search-form/ 时看到search_forms.html 页面

我有一个位于 /src/project/urls.py 的主 urls.py 文件

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^admin/', include(admin.site.urls)),   
)

我还有一个位于 /src/polls/urls.py 的投票 urls.py 你可以看到我已经尝试了一些解决方案。

urlpatterns = patterns('',
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^(?P<pk>\d+)/$', views.DetailView.as_view(), name='detail'),
    url(r'^(?P<pk>\d+)/results/$', views.ResultsView.as_view(), name='results'),
    url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),


    #this one will bring me to the vote page when i type search-form in the browser
    #http://127.0.0.1:8000/polls/2/search-form/
    #url(r'^(?P<poll_id>\d+)/search-form/$', views.vote, name='search-form'),


    #url(r'^/search-form/$', views.search_form, name='search_form'),

    url(r'^search-form/$', views.search_form),

    #url(r'^(?P<poll_id>\d+)/search-form/$', views.search_form, name='search-form'),

    #url(r'^search-form/$', views.search_form),
    #url(r'^$', views.search_form, name='search-form/$'),  
   # url(r'^(?P<poll_id>\d+)/detail_dropdown/$', views.vote, name='detail_dropdown'),
)

我有一个位于 /src/polls/templates/polls/search_form.html 的 search_form.html 页面，其代码与教程中的代码相同

我还在 src/polls/views.py 使用以下代码设置了 search_form 视图

def search_form(request):
    return render(request, 'search_form.html')

非常感谢任何帮助。谢谢。

编辑：浏览器错误消息

我已经尝试使用未注释的 url，这是错误消息。

您问题中未注释的网址应该可以工作。给它命名是个好习惯。

url(r'^search-form/$', views.search_form, name="search_form"),

错误消息说明了问题所在。

TemplateDoesNotExist at /polls/search-form/

search_form.html

您已将模板放在“polls/search_form.html”中，但在您看来，您正在使用模板“search_form.html”。

要解决此问题，您可以将视图更改为

return render(request, 'polls/search_form.html')

或者您可以将模板移动到父目录/src/polls/templates/。

如果上面的 url 模式不起作用，请更新您的问题，说明当您在浏览器中转到 /polls/search-form/ 时遇到什么错误。
