I didn't try it with django but maybe closure is the solution.
Try this:

<code>
#!/usr/bin/env python

class MyView(object):
    def __init__(self):
        self.visited = []
    def index(self, *args):
        self.visited.append("index")
        print "%s.index: %r" % (self.__class__.__name__, args)
        return "response from index"
    def detail(self, *args):
        self.visited.append("detail")
        print "%s.detail: %r" % (self.__class__.__name__, args)
        return "response from detail"
    def error(self, *args):
        self.visited.append("error")
        print "%s.error: %r" % (self.__class__.__name__, args)
        return "response from error"

def make_view(obj, methodname):
    def view(*args):
        try:
            return getattr(obj, methodname)(*args)
        except AttributeError:
            return obj.error(*args)
    return view

view_obj = MyView()

index = make_view(view_obj, "index")
detail = make_view(view_obj, "detail")
download = make_view(view_obj, "download")

print index("request to index")
print detail("request to detail", 25)
print download("request to download", "abc", 99)
print
print "\n".join(view_obj.visited)
</code>

index, detail and download functions can be mapped
in urls.py now.
