I tried this: get trace_errors.error_email = email_to get trace_errors.smtp_server = smtp_server get trace_errors.smtp_port = smtp_port get trace_errors.from_address = error_email_from which works, but only if the values of email_to, smtp_server, ... are effectively specified. If they are not present, this gives an error at startup of the application. My goal was to add the above snippet (or a variation of it) in our default ini files, and ini file template, so that users don't need to care about it. However, we do not have default values for these settings. Do you know how to achieve this? Also, I couldn't find documentation for these 'get' keyword. The 'set' is documented in PasteDeploy documentation, but 'get' is not. Thanks, Thomas -- You received this message because you are subscribed to the Google Groups "TurboGears" group.
