Hi,
I made another test, I tried the errorhandling as explained in cherrypy
by using exclusively cherrypy without tg, and guess what: it works! :-)
but when I import turbogears into the script it doesn't work anymore :-(
here the test script (it works only without turbogears):
import cherrypy
#import turbogears ##### uncomment this line and it doesn't work!!!!
def handle_error():
cherrypy.response.body = ["Sorry, an error 500 occured. The admin
has been notified."]
class Root:
_cp_config = {
"request.error_response": handle_error
}
@cherrypy.expose()
def index(self, **kw):
raise SyntaxError("forcing an error 500")
if __name__ == "__main__":
cherrypy.config.update(config='dev.cfg')
cherrypy.quickstart(Root(), "/", {})

Thanks for replying to my question Christoph,
I did exactly as you said but it doesn't work yet....
Using pdb I can see that request.error_response has handle_errror()
assigned to,
before the error 500, but then it changes again, and I don't know
where and what changes it,
take a look ...
....debugging my controller...
import pdb;pdb.set_trace()
(Pdb) cherrypy.request.error_response.func_name
'handle_error'
### as you see at this point request.error_response has
indeed the handle_error assigned to
(Pdb) c

Hi Jose,
your code is different from what is written in the docs.
Particularly,
the handle_error() should be taken literally from there.
Just copy the code in the docs into a module errorhandling.py,
then add
from .errorhandling import error_page, handle_error
at the top of your project, and add this to your RootController
class:
if config.get('error_catcher.on', False):
_cp_config = {
'error_page.default': error_page,
'request.error_response': handle_error
}
That definitely works for me, inculding the 500 errors.
