i have make changes in django project , though i'm familiar python, i'm not django. this situation: i have table field "active". need let users sort table based on value of field (yes/no). i looked views.py , realized there view sorts table based on id: users = user.objects.all().order_by('id') my questions are: how can make view sort table based on url parameter? do have create view or can use same kind of modifications? you can use same view. def myview(request): get_param = request.get.get('my_param', 'id') #some more processing users = user.objects.order_by(get_param) #note - dont need `all()` #rest of code here.

i have pyqt application ready release. it's first attempt on gui thing bare me. works pretty , have 1 more thing wrap up. love software updates itself: check url new version; new version found; notify user of updates (click) → update . the problem don't know how perform update. check, find new version, download , must close application , execute installer of new version. if close can't execute else, if execute installer can't close application. based on user choices program downloads , installs third party software needs same thing: close before install program, restart after install program. after downloading installer newer version, can use atexit.register() os.exec*() run installer, e.g. atexit.register(os.execl, "installer.exe", "installer.exe") . make installer start when application exit. application exit after os.exec*() call, no race condition occur.

this question closely relates how run 2 python loops concurrently? i'll put in clearer manner: questioner asks in above link, like for in [1,2,3], j in [3,2,1]: print i,j cmp(i,j) #do_something(i,j) but l1: in [1,2,3] , j in [3,2,1]: doesnt work q1. amusing happened here: in [1,2,3], j in [3,2,1]: print i,j [1, 2, 3] 0 false 0 q2. how make l1 work? not multithreading or parallelism really.
