\d+ ensures you will only get naturals, but django will not perform any 
conversion automatically. Especially not here as it would require introspecting 
the regular expression to see which pattern was matched and whether it is 
convertible.

question about "\d" in url pattern

2012-02-26 Thread Zheng Li 
url(r'^friend_page/cheer/confirm/(?P\w+)/(?P\d+)/(?P\d+)/$', 
'cheer_confirm', name = 'friend_page'),

def cheer_confirm(request, fid, key, point):
data = {
'point' : 10 + point,
}
...

i got 
TypeError: unsupported operand type(s) for +: 'int' and 'unicode'

i did "print type(point)", and got type(unicode)
apparently, point is not int.

i thought "\d+" in url promises i can get an int point in cheer_confirm, and am 
i wrong?
