Django URLS，使用？在URL中 [英] Django URLS, using a ? in the URL

问题描述

我正在尝试一些Django网址匹配。

我想要几个网址，我有一个 http://mysite.com/base?sort=type1/ ， http://mysite.com/base?sort=type2/ 等。

我不知道如何URL匹配这些表达式：我对Django非常新鲜，从未使用过Reg Ex。

我在基础应用程序中的urls.py有什么：

  url（r'^ $'，'base.views.main，name ='main'），
  

我无法弄清楚将我的网址与问号相符。

我正在尝试像

  url（r'^？sort = popular / $' 'base.views.main_popular'，name ='main_popular'），
  

感谢您的帮助！ p>

解决方案

？不会匹配？在url里面，它有自己的意思，你可以在这里查看：

Python正则表达式
如果要匹配？的确切字符在你的url里面，你必须以某种方式逃避它（因为它在RegExs中有一个意义），所以你可能想用\（一个反斜杠）
来逃避它，所以你会写\？排序...

编辑：

好​​的，你在评论中说过，似乎这是你的问题， main？sort当您使用 GET / main / 的模板时，会在您的网址模式中发生=流行 $ c>方法字典参数 sort = popular ，只需编写一个区分 GET 和 POST ，在 GET 部分中，像 sort_by = request.GET.get（'sort' ''），然后按sort_by变量的值进行排序，将像：

  def main_handler（request）：
如果request.method ==POST：
 whatever ... 
如果request.method ==GET：
 sort_by =请求。 GET.get（'sort'，''）
如果sort_by：
按什么排序指向
返回排序的模板
返回render_to_response（该页面及其参数）
  / pre> 
 
 
放弃那个？在url模式的内部，当您请求具有GET参数的页面时，该模式将被添加。
 
I am trying to do some Django URL matching.

i want a few urls where i have http://mysite.com/base?sort=type1/, http://mysite.com/base?sort=type2/, etc.

I can't figure out how to URL match these expressions:  I'm very new to Django and never used Reg Ex before.

What I have for urls.py in my "base" application is:
url(r'^$','base.views.main, name='main'),
I can't figure out what to put to match my urls with question marks.

I'm trying something like 
url(r'^?sort=popular/$', 'base.views.main_popular', name='main_popular'),
Thanks for help!
解决方案
? won't match an "?" inside the url , instead it has its own meaning which you can look it up here :

Python Regular Expressions
If you want to match the exact character of "?" inside your url , you have to somehow escape it ( cause it has a meaning in RegExs ) so you might wanna escape it by a "\" (a backslash )
so you would write \?sort ....  

EDIT :

Okay so with what you've said in comments , seems here's your problem , main?sort=popular occurs on your url pattern when you are rendering the template for /main/ with the GET method dictionary argument of sort=popular, just write a function that distinguishes between GET and POST , in the GET part , have sth like sort_by = request.GET.get('sort','') and then sort accordingly with the value of sort_by variable, would be sth like :   
def main_handler(request):
     if request.method == "POST":
           whatever ... 
     if request.method == "GET" :
           sort_by = request.GET.get('sort','')
           if sort_by:
                 sort by what sort points to 
                 return "the sorted template"
     return render_to_response(the page and it's args)
and let go of that ? inside the url pattern , that's added when you request a page with a GET argument.
