How do I pass variables in django through the url?
提问by sharataka
I am trying to pass a few variables but I am having some trouble and specifically have 3 questions. How do I encode the url string to take into account the special characters in the string? What is the correct regex I should use given the strings? And how do I decode the urls that have been encoded?
我试图传递一些变量，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？以及如何解码已编码的网址？
view
看法
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?
template
模板
<a href="/{{url}}" > <img src="img.png" > </a>
urls.py
网址.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 function
视频播放器功能
def video_player(request, author, video, related):
#how do I decode the urls that are encoded

I tried it without related to see if it works but am still getting an error.
我在没有相关的情况下尝试了它，看看它是否有效，但仍然出现错误。
template:
模板：
<a href="{% url 'reserve.views.video_player' author video title %}" >
url:
网址：
url(r'^partner/(?P<author>[-\w]+)/(?P<video>[-\w]+)/(?P<title>[-\w]+)/$', 'video_player'),
I get this error:
我收到此错误：
NoReverseMatch at /partner/BuzzFeed/ Reverse for ''video_player'' with arguments '('BuzzFeed', 'fXkqhhIlOtA', 'NY Yankees: 6 Essential Pieces of Postseason Memorabilia')' and keyword arguments '{}' not found.
NoReverseMatch at /partner/BuzzFeed/ 反向“video_player”，参数为“('BuzzFeed', 'fXkqhhIlOtA', 'NY Yankees: 6 Essential Pieces of Postseason Memorabilia')' 和关键字参数 '{}' 未找到。

Pass these variables as it is to template, there use url, before sending to template just do this in view.
将这些变量按原样传递给模板，使用url，在发送到模板之前只需在视图中执行此操作。
View.py
查看.py
related = urllib.quote(related, safe='')
template
模板
<a href="{% url 'path.to.video_player' author video related %}" > <img src="img.png" > </a>
Url.py
网址.py
url(r'^partner/(?P<author>[-\w]+)/(?P<video>\w+)/(?P<related>\w+)/$', 'video_player'),

If you want to go without related parameter, or if there is doubt video can also be None then just do this in your view:
如果您想不使用相关参数，或者有疑问 video 也可以为 None ，那么只需在您的视图中执行此操作：
def video_player(request, author, video=None, related=None):
now you can use the url by
现在您可以通过以下方式使用该网址
<a href="{% url 'path.to.video_player' author video %}" > <img src="img.png" > </a>

in newer versions of python you could simply just type: Example:
在较新版本的python中，您只需键入：例如：
path('<int:id>/delete/', delete_view, name = 'delete'),
path('<int:id>/delete/', delete_view, name = 'delete'),
