Hi Anand,
Thanks for the quick reply. In my main sitemanager app what I do is use a
cookie to find out the language of the visitor, according to that cookie a
locale template path is chosen, so what I have is a hook which I then add as
a preprocessor:
+++
def render_hook():
cookies = web.cookies(lang="en")
lang = cookies.lang
if lang in settings.VALID_LANGS:
locales_path = os.path.join(settings.TEMPLATES_PATH, "%s/"%(lang))
else:
locales_path = os.path.join(settings.TEMPLATES_PATH,"en/")
web.ctx.render = web.template.render(locales_path, globals={'session':
web.ctx.session})
++++
As I said the function is loaded by a preprocessor:
+++
app.add_processor(web.loadhook(render_hook))
+++
I then return the webs like this:
+++
return web.ctx.render.base(content=web.ctx.render.search(...))
+++
Perhaps there is something wrong in doing this and the preprocessor forces a
recompilation on each request?
