This should work as well — as simply as possible — using globals all
around. Don't add any more complexity than the statements `visitors +=
and -= 1` or your run the risk of no longer being thread-safe. But if
this is all you need..
## code.py
visitors = 0
render = Render('templates', base='base', globals={'visitors': visitors})
class Landing:
def GET(self):
return render.landing()
class SignIn:
def POST(self):
visitors += 1
return 'one more user eating my cycles'
class SignOut:
def POST(self):
visitors -= 1
return 'one less user eating my cycles'
##templates/base.html
$def with (document)
<html><body>
<article>$:document</article>
<footer>Currently $visitors visitors.</footer>
</body></html>
## templates/landing.html
$def with ()
<p>Welcome to the landing of my site.</p>
## output
<html><body>
<article><p>Welcome to the landing of my site.</p></article>
<footer>Currently 0 visitors.</footer>
</body></html>
