Question

GetUsage/08-03-2011

to match this url i have used following regular expression in urls.py ( python & django)

('^GetData/((0?[1-9]|[12][0-9]|3[01])[- /.](0?[1-9]|1[012])[- /.](19|20)?[0-9]{2})*',GetData)

and inside the views.py following method is configured to accept the date

def GetDataData(request,sdate):

but when i fire following request

http://[ipaddress]/GetUsage/08-03-2011

i am getting following error

GetData() takes exactly 2 arguments (5 given)

as it is counting 08-03-2011 in a seperate 5 parts , but i want to get it in a single parameter i.e. in sdate

Answer 1

Each regexp group within () is being passed to GetData() as an argument. If you don’t want groups to be generated by some of them, but still want to use parens, use (?:whatever) for non-grouping parens.

EDIT: You probably want something like:

('^GetData/((?:0?[1-9]|[12][0-9]|3[01])[- /.](?:0?[1-9]|1[012])[- /.](?:19|20)?[0-9]{2})*',GetData)
