This has nothing (or very few) to do with inheritance. You'd have the same behaviour (ie : first getting all data, then building html, then return the response) without using inheritance in your template. > etc > > The first approach is much more elegant and leads to easier to > maintain code.

You are correct to assume that no rendering can happen before you send a response to the client, indeed. > Is there a way to get the best of both > worlds? Maybe using generators? Thank you. You can of course pass an iterable to your reponse object (read the doc for the HttpResponse object), but then you'll have to organize your code very differently, and not necessarily in the most readable and maintainable way. As far as I'm concerned, I'd first try to profile and possibly optimize the "very long computation" part. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
