Question

我正在尝试从html的div中的定位标记发送字符串值，即“ news.id” 到views.py。我不确定“ single_post / {{news.id}}”是否正确。 news.id可能是5c9f94516fe3c761e420333a（用于正则表达式）

.html

<div class="post-continue-btn">
    <a href="single_post/{{ news.id }}"  class="font-pt">Continue Reading 
        <i class="fa fa-chevron-right" aria-hidden="true"></i></a>
</div>

我已经以某种方式通过了这个，但是现在停留在URLs.py上，这是我的URL代码

URL.py

urlpatterns = [
    url(r'^$',views.index,name='index'),
    url(r'^single_post/$', views.single_post),
    url(r'^<slug:slug>/$',views.single_post),
    url(r'^index/single_post/$', views.single_post),
    url(r'^index/$', views.index),
    url(r'^contact/$', views.contact),
    url(r'^about_us/$', views.about_us),
    path('admin/', admin.site.urls),]

views.py

def single_post(request):
    project_name = request.GET.get('id')
    context = {'doc_data': search_query.doc_data(project_name)}
    return render_to_response('DeepNews/dummy.html', context)

如何在.html锚标记中正确编写代码，然后在URL.py中使用这种类型的字符串“ 5c9f94516fe3c761e420333a”的正则表达式是什么，这样我就可以在views.py中获取“ news.id”的值< / p>

Answer 1

在您的网址上，将参数传递到单个帖子网址，并为其命名，以免在应用程序上使用硬编码的网址

urlpatterns = [
    url(r'^$',views.index,name='index'),
    url(r'^single_post/(?P<uuid>[a-z0-9-]*)/', views.single_post, name='sigle-post'),
    url(r'^index/$', views.index),
    url(r'^contact/$', views.contact),
    url(r'^about_us/$', views.about_us),
    path('admin/', admin.site.urls),]

然后在模板上，您可以使用url标签告诉django为您构造url

<div class="post-continue-btn">
    <a href="{% url 'single-post' news.id %}"  class="font-pt">Continue Reading 
        <i class="fa fa-chevron-right" aria-hidden="true"></i></a>
</div>

在您看来，您会收到论点

def single_post(request, uuid):
    project_name = uuid
    context = {'doc_data': search_query.doc_data(project_name)}
    return render_to_response('DeepNews/dummy.html', context)

Answer 2

在您的urls.py

中

urlpatterns = [
    url(r'^$',views.index,name='index'),
    url(r'(?P<single_post>[^/]+)/(?P<slug>[-\w]+)$', views.single_post, name='sigle-post'),
    url(r'^index/single_post/$', views.single_post),
    url(r'^index/$', views.index),
    url(r'^contact/$', views.contact),
    url(r'^about_us/$', views.about_us),
    path('admin/', admin.site.urls),]
