I'm using the inspect module in my python product to step back when doing some debugging. My code looks something like this::
class MyProduct:
def hasRole(self, r): for i in range(25): try: print inspect.stack()[i][3], print inspect.stack()[i][2], except IndexError: break
It works wonderfully well except when the caller of hasRole() is a Page Template defined with the PageTemplateFile function. (it might be equally bad with a ZODB persistent template I think).
Look at how "ExceptionFormatter" (in package "zExceptions") examines the stack for "__traceback_info__" and "__traceback_supplement__". You can in a similar way detect when you are in a PageTemplate method. PageTemplates have attributes describing the current sourcefile and line number. -- Dieter
