Using GPIO in webpage

Question

I am using Django 1.5.4 to design a web page in which i want to use GPIO, but i got following error:

"Noﾠaccessﾠtoﾠ/dev/mem. Tryﾠrunningﾠasﾠroot! "

in browser. Since web browser itself is an application, how can i assign "root" privileges to it when it tried to render a web page ? If it can be done without any need to install anything that would be better as other frameworks/applications who are able to use GPIO in web page must have made some tweaks.I tried searching for similar questions for this area but couldn't find this specific case ( django + gpio access).

Any help would be greatly appreciated.

Thanks

No.... not the browser. The web server. It needs to be running as root (make sure you understand what django is - it's server-side.) — Jonathon Reinhart

You don't have to run the webbrowser as root but your django app (the webserver).

Of course running a web application as root is an incredibly bad idea (even on a pi), so you might want to use a separate worker process (e.g. using celery) that runs as root and accesses the GPIOs.

Did you verify it's running as root or did you just assume it to be the case?

ya..i did that verification. Django server is running as root! The problem when i tried to use GPIO.input(), i got this error. Isn't there separate way to achieve the same without using this method ?
