如何通过 url 在 django 中传递变量？

Question

我正在尝试传递一些变量，但我遇到了一些麻烦，特别是有 3 个问题。 如何编码 url 字符串以考虑字符串中的特殊字符？ 给定字符串，我应该使用什么正确的正则表达式？ 以及如何解码已经编码的url？

查看

author = 'foo'
video = 'bar123-456'
title = 'Santorum: "I'm Not a Visionary"' # in my version, it is referencing another variable so the syntax error doesn't occur. But I left it in here because I want to know how to deal with " and '.
related = 'http://gdata.youtube.com/feeds/api/users/haha/uploads?v=2&max-results=50'

url = urllib.quote('partner/' + author+ '/'+ video+'/'+ title + '/' + related)
#How do I encode this url string above to take into account the special characters in the string?

模板

<a href="/{{url}}" > <img src="img.png" > </a>

urls.py

url(r'^partner/(?P<partner_name>[-\w]+)/(?P<video_id>[-\w]+)/(?P<video_title>[-\w]+)//(?P<related_feed>)/$', 'video_player'),
#do I have to add anything to the regex?

video_player函数

def video_player(request, author, video, related):
    #how do I decode the urls that are encoded

我尝试了没有相关的，看看它是否有效，但仍然出现错误。

模板：

<a href="{% url 'reserve.views.video_player' author video title   %}" >

网址：

url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<title>[-\w]+)/$', 'video_player'),

我收到此错误：

NoReverseMatch 在 /partner/BuzzFeed/ 使用参数 '('BuzzFeed', 'fXkqhhIlOtA', 'NY Yankees: 6 Essential Pieces of Postseason Memorabilia')' 和关键字参数 '{}' 的参数反向。

完整的 urls.py

urlpatterns = patterns('reserve.views',
    url(r'^$', 'index'),
    url(r'^browse/$', 'browse'),
    url(r'^faq/$', 'faq'),
    url(r'^about/$', 'about'),
    url(r'^contactinfo/$', 'contactinfo'),
    url(r'^search/$', 'search'),
    (r'^accounts/', include('registration.backends.default.urls')),
    (r'^accounts/profile/$', 'profile'),
    (r'^accounts/create_profile/$', 'user_profile'),
    (r'^accounts/edit_profile/$', 'edit_profile'),
    url(r'^products/(?P<product_name>[-\w]+)/reviews/$', 'view_reviews'),
    url(r'^products/(?P<product_id>\d+)/reviews/$', 'view_reviews'),
    url(r'^user/(?P<user_id>[-\w]+)/$', 'view_reviews_user'),
    #url(r'^category/(?P<category_name>[-\w]+)/$', 'view_product_category'),
    url(r'^partner/(?P<partner_name>[-\w]+)/$', 'partner_channel'),
    url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<video_title>[-\w]+)/$', 'video_player'),
    url(r'^partner/(?P<author>[-\w]+)/(?P<video>\w+)/(?P<title>\w+)/$', 'video_player'),
    url(r'^admin/', include(admin.site.urls)),
)

Answer 1

在较新版本的 python 中，您只需键入： 示例：

path('<int:id>/delete/', delete_view, name = 'delete'),

Answer 2

将这些变量按原样传递给模板，使用url，在发送给模板之前，只需在视图中执行此操作即可。

View.py

related = urllib.quote(related, safe='')

模板

<a href="{% url 'path.to.video_player' author video related %}" > <img src="img.png" > </a>

Url.py

url(r'^partner/(?P<author>[-\w]+)/(?P<video>\w+)/(?P<related>\w+)/$', 'video_player'),

如果您想不使用相关参数，或者如果您怀疑视频也可以是无，那么只需在您的视图中执行此操作：

def video_player(request, author, video=None, related=None):

现在你可以使用 url 了

<a href="{% url 'path.to.video_player' author video %}" > <img src="img.png" > </a>
