Instead of using base templates I usually create a seperate template for
every page that has the <html> and everything and include common
elements from there.
To do this without having to pass the render object around everywhere I
implement a trick suggested by Ken in [1]:
render = web.template.render("templates/", cache=False)
web.template.Template.globals['render'] = render
Now, in every template I can do things like these:
<head>
$:render.head("Special page")
<meta name="robots" content="noindex, nofollow">
</head>
With a file template/head.html:
$def with (title)
$if title:
<title>$title -- UNISCA Contacts</title>
<style type="text/css">
@import url("/static/basic.css") projection, screen, tv;
</style>
Note how you can still easily add extra <meta> tags, for example.
I believe this is a good compromise between readability, flexibility and
consistency.
(To take it even further, I sometimes add this to my code file:
web.template.Template.globals['py'] = web.storify(__builtins__)
Now I can access all python builtins in my templates, like:
$if py.isinstance(value, py.int):
$value
$else:
<pre>$value</pre>
But I prefer not admit this to too many people ;P)
