[Zope-dev] How do I call careful_getattr()?

My TableView class allows the user to enter the name of a method to be called. Right now the code to call the method looks like this: rowIds = getattr(folder, self.rowIdsMethodName)() "self.rowIdsMethodName" gives me the name of the method, then I use getattr() to find the method, and then I call it. But, it would be better if this was security checked, so that the user couldn't type in something like "manage_delObjects" for the method name. :) Is this a job for careful_getattr() ? How do I call it? In particular, what is the "md" argument? I'm inside of a Product method superclassing a ZClass, so I've got a "self" and a "REQUEST" to work with. Thanks, Andrew
