Re: Difficulty in passing positional arguments in url !!!

I think that it is the question mark in your url pattern that is causing the problem.  In a real url, question mark separates the path from the query parameters.  Parentheses in url patterns are for capturing parts of the path, and are not associated with query parameters.  Just leave out the ? and it may just work.

(Of course, if you also want this parameter filled in by the submission of a form, you would be better to put the email address in a query paramater, as a form submission would.)

If i remove the  href line from my template ,profile.html then my app runs normally !!

So obviously there is some mistake that i am doing while using href ,or sending url parameters or  in extracting it. Also what is the use of reverse() in django i read the documentation but i am unable to understand it !!
