Probably you should try using:
m = Medecine.objects.get(pk = i)
Instead of using:
m = Medecine.objects.get(id = i)
Also, try to handle the DoesNotExist and similar exception once you
try to retrieve the object using the /get()/ method. Also you can
reduce the look by using:
del_ids = request.POST.getlist('del_id')
Medecine.objects.filter(id__in = del_id).delete()
Which should be faster than your loop.
