问题
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!
回答1:
? 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.
回答2:
You don't match these against the regex. The elements after the ?
are not part of the URL, they are query parameters which can be accessed from your view via request.GET
.
