Yes, I know I can make it work by returning webob.exc.HTTPException objects as response. But the point was to decode JSON request at view initialization phase and raise webob.exc.HTTPBadRequest if needed, so in subclasses at request processing phase (__call__ method) I always will have well-formed request objects.
By looking at the Router code it seems that handling repoze.bfg.exceptions.NotFound/Forbidden is some kind of bonus feature for views, because it is more intended for serving repoze.bfg.security and context finding/view lookup mechanisms, isn't it? > The most reasonable answer is that this *does* work: > > class JSONView(object): > def __init__(self, context, request): > try: > request.json = json.loads(request.body) > except ValueError: > return webob.exc.HTTPBadRequest() > self.request = request > > Instances of exceptions in webob.exc are themselves responses, so they can > be returned from a view function. > > I can see the attraction in making the router able to handle a WebOb > exception that implies a response.
