First, let me take some Motrin for my very sore rear end. I have been
reading documentation. In fact, I started with the tutorials on the
site that walks you through writing the polling application, then
moved on to some docs at http://www.djangobook.com. It's sometimes
hard to find the one mention of a certain subject when you don't know
what it is you are really looking for. The page I found on template
blocks, located here http://www.djangobook.com/en/beta/chapter04/,
didn't really tell me much.
I think the biggest problem is that I have some overlap of experience
with JSPs, PHP, and Ruby, all of which use an in-line server side
include tag similar to the one here. I guess in my reading it just
seemed to make sense that these where server side includes and not
just some template replace thing, but again that just shows my age on
the product.
I do sincerely thank you for helping me get it straight. I know that
sometimes the newbs ask very dumb questions. As someone that has had
to deal with them in other languages I know it can be frustrating and
repetitive. You sometimes have to remember that the skills you have
had to start somewhere, and that you probably made your own stupid
mistakes and got stuck on something just as us who are starting out
have.
