Hi,
Does anyone have any examples/advice re implementing an error handling
approach. In particular the requirements/idea I had regarding passing
exceptions/error’s from the model layer back to the controller layer is
that:
-
common exception method to be used across all models/controllers
-
this method handles (a) logging error to logs for developer later (b)
providing an approach user error message, © helping the controller
what to
do next [e.g. is error recoverable, let user try again or not], and (d)
triggers a pager/SMS message for high priority items -
parameters for error method:
- user facing error message (to be used in a view)
- developer focused error message
- stack trace / error detail (e.g. SQL error message, etc) - i.e.
technical detail re root cause hopefully - priority (ERROR / CRITICAL) - controller uses to determine whether
to
stay on same view page (e.g. error) or that
it is a system error (CRITICAL) so just take user back to home page
afterwards. This could also be used
to determine a pager message to the developer should be fired off or
not
Any comments/suggestions sample code would be appreciated.
Regards
Greg
