IIRC, response._caller acts like a function decorator. So it takes a
function and returns a function. I used to use Genshi like this:
def renderGenshi(func):
def _render():
output = func()
if not isinstance(dict, output):
return output
else:
# real Genshi render code goes here
return Genshi.render(response._view, output)
return _render
response._caller = renderGenshi
Naturally it was more complicated than that, but you get the idea.
That said, make sure Jinja2 is really what you want. I thought I liked
it until I learned that its context is immutable. (This means you can't
set response.title in a template and expect that change to propagate to
an included or extended template file. This was a deal-breaker for me.)
In case you're curious, I switched off of Genshi back to web2py
templates because Genshi only works on normal cPython platforms. It
blows up on Jython or AIX Python.

Its going to be your best bet in using a different templating
language. YOu will have to make sure to only parse your HTML requests
and not json/download etc.
Basically, response._caller is a function, that returns a string which
is the html.
So you would instead of response.render(d) you would do
jinja2.render(d) where d is the dict returned from the action, you
will of course have to tell jinja where to find templates and which
template to render based on action
jinja.render(d, '/applications/init/views/' + request.action+'.html')

Hi,
I want to replace web2py's template engine with Jinja 2
<http://jinja.pocoo.org/2/>, anyone has some experience doing
something similar? I'm trying to assign response._caller with a
custom function, but I'm not having much success, is that the
right way?
Thanks,
