I've developed a very simple webapp.RequestHandler subclass that does a couple of useful things that I need in my GAE app. They seem like pretty basic things that are worth sharing – though anyone could have done it themselves in five minutes.
class BBRequestHandler(webapp.RequestHandler):
# Render a template with standard data mixed in.
def render(self, template_name, template_data = {}):
template_data.update(self.sundries())
self.response.out.write(template.render('view/' + template_name, template_data))
# Forward the request to a different handler. Assumes GET.
def forward(self, handler_class):
handler = handler_class()
handler.initialize(self.request, self.response)
handler.get()
# Standard template data required for most pages.
def sundries(self):
return {'logout':users.create_logout_url('/')}
The intention is that sundries() should return whatever standard data your pages require that's not specific to individual pages. In my case that's data that's required for the header, footer and sidebar – like the logout URL.
You may notice that I'm not using the Python docstring format. I just can't quite bring myself to do that just yet, though I have got used to the indentation-is-block thing.
