Python: Getting Genshi to Output FBML in Pylons
This took me quite a while to figure out, so I'm going to blog it for the sake of Google. To get Pylons to tell Genshi to output XHTML so that you can output FBML for Facebook, edit your environment.py and do:
# Customize templating options via this variableMy templates now start with:
tmpl_options = config['buffet.template_options']
# Without this, all the FBML tags get stripped.
tmpl_options['genshi.default_format'] = 'xhtml'
<fb:fbml xmlns="http://www.w3.org/1999/xhtml"
xmlns:py="http://genshi.edgewall.org/"
xmlns:xi="http://www.w3.org/2001/XInclude"
xmlns:fb="fbml">

@expose(template="template name" format="xhtml")
I needed to pass some template variables through to a json template, and I wanted Genshi to completely bypass its XML-parsing functionality.
I used a text renderer:
# Genshi Imports
from genshi.template import TemplateLoader, TextTemplate
# pkg_resources: see
# http://python.org/dev/peps/pep-0365/
import pkg_resources
# Load my template once, at startup.
# We need to form a relative path from the
# pkg_resources, because if we're running
# from a production .egg other methods of
# building a file path will fail.
MY_TMPL =
pkg_resources.resource_stream(__name__,
'../templates/my-template.json').read()
# Later on in my controller methods:
# **kargs: c=c, foo=bar, etc.
return TextTemplate(MY_TMPL)
.generate(**kargs).render('text')
There might be simpler ways to do this(?),
but this was the method I stumbled upon.
