I somewhat suspect that you aren't going to get the code as by
default generated by Cheetah to play well with publisher. As to
your original custom handler, you could clean it up somewhat
by using something like:
start = "/python/"
from mod_python import apache
import string
def handler(req):
req.content_type = "text/html"
module_name = string.replace (req.uri, start, "")
# try:
# exec ("""import %s
#tmpl = %s.%s()
#tmpl.req = req""" % (module_name, module_name, module_name))
# except ImportError:
# return apache.HTTP_NOT_FOUND
module = apache.import_module(module_name)
if not hasattr(module,module_name):
return apache.HTTP_NOT_FOUND
tmpl = getattr(module,module_name)()
tmpl.req = req
req.send_http_header()
req.write(tmpl.respond())
return apache.OK
I still see some issues with this code in as much as I think it
requires everything to be in the one directory. Ie., can't have
subdirectories. Using "start" as a fixed value is not good, but
that can also be fixed. Also, you can't mix different file types
in the same directory.
When I get a chance, I'll write you a better version of this
which would fix these problems and provide new abilities as well.
I am surprised though that someone hasn't already written a
better handler for integrating Cheetah with mod_python.
BTW, I am not on the Cheetah mailing list, so ensure any responses
also go back to the mod_python list as well.
