Question

I m running the micro framework Bottle on Google App Engine. I m using Jinja2 for my templates. And I m using Beaker to handle the sessions. I m still a pretty big Python newbie and am pretty stoked I got this far :) My question is how do I access the session data within the templates? I can get the session data no problem within the actual python code. And I could pass the session data each time I call a jinja template. But since I need the session data in the main menu bar of the site... that means I would have to pass it on every single page. Does anyone know if I can access it directly in the templates?

For example I need the session data for my header links:

Home | FAQ | Login

or

Home | FAQ | Logout

Any help is greatly appreciated! :D

You can add things to the Jinja2 environment globals if you want them to be accessible to all templates. See this page for additional information.

Update:

A simple example is, for your setup code:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader( yourapplication ,  templates ))

Then, in your request handling code:

env.globals[ session ] = session # Your session
# Your template can contain things like {{ session[ key ] }}
template = env.get_template( mytemplate.html )
print template.render(the= variables , go= here )
#return response using rendered data
