Comment (by David Svenson):
The following function takes a new-style middleware class and makes a view
decorator out of it. It's used in code that me and @pelme are working on,
though not as a decorator.
{{{
def decorator_from_middleware_new(new_middleware_cls):
def view_decorator(view_function):
def view(request, *args, **kwargs):
def get_response(request_inner):
assert request is request_inner
try:
return view_function(request, *args, **kwargs)
except Exception as e:
new_middleware.process_exception(request, e)
return HttpResponseServerError()
new_middleware = new_middleware_cls(get_response)
return new_middleware(request)
return view
return view_decorator
}}}
