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

Thanks for replying Bill :D

Ooops !!

 i removed the question  mark but it is till not working !!  

The problem is that i dont have a form and i think form maynot be suitable to for application !!

MY requirements :-

i have some list of items and clicking on any of it should go to the view and tell me which item was clicked 

i.e.  These are the items which are to be clicked 

      * hp@hp.com

      *abc@gmail.com

      *xyz@gmail.com

Now if user clicks abc@gmail.com

      My view should know that abc@gmail.com was clicked 

     i.e. item selected (abc@gmail.com) should be passed to my view and i should be able to perform some calculation with this email  !!!

Any clue as to how to achieve this goal !!

I thought using url regex extraction ,i will be able to pass paramters to my views

  like  

     acceptfriend/abc@gmail.com/  or

    acceptfriend/hp@hp.com/       or

    acceptfriend/xyz@gmail.com/     

 

 will match      r'^acceptfriend/(\w+)/$'    and this captured parameter ((\w+)/)  will be passed to my appropriate view !!

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 !!
