This is the side bar in template. The sidebar will change based on user roll.

I use request.user to decide the user roll. it seems to be that the page is stored in the browser when i first load this page. So when i update the page after i login in, the page i loaded before didn't change the user in sidebar and topbar. i disabled cookies and cache in my browser but it still doesn't work, hope anyone hat a answer!
