Yeah, I did a quick check in the interpreter and this is indeed very cool.
There is another thing though that worries me (but just a little).
Often, when I write views, it's nice to be able just to return 404 or
302 at any moment and not proceed with a current function. For 404 it
can be always done by just raise Http404. Inside views functions 302
can also be easily done by return HttpResponseRedirect('location').
But when it is done inside a method in a class, it can't be done so
easily. For example:
class SomeResponse(HttpResponse):
def __init__(self, *args, **kwargs):
self.some_method(*args, **kwargs)
def some_method(self, *args, **kwargs):
# need redirect here - this won't work
return HttpResponseRedirect(..
Is there any elegant solution, which would allow to break, just when
it's needed?
