RE: [Zope] Automatically run an external method?
I agree that this is (or event triggers in general are) a useful soft of thing. I think one thing that will eventually come out of ComponentArchitecture/Zope3X efforts will be the service-ization of such infrastrucuture as a standard component of Zope the way that workflow is a standard component of the CMF...

Is it possible to automatically run an external method every time a file is saved? That is, is there some kind of file where I can say "when you're saved, call this method?"t

Well, I can run the program by hand for the time being but it would be convenient to figure out how to do it automatically. It sounds like I need to make a new product? Haven't learned how to create one of those yet... *********** REPLY SEPARATOR *********** On 12/15/01 at 5:08 PM sean.upton@uniontrib.com wrote:

I think what you want to do is to make a new zClass where you subclass the class you are interested in, and then write a new form and a new action where you put additional logic. Zope can generate most of the code for you when you make the new zClass. regards Max M

Right. There's no event hooking API in core Zope yet, just a small number of hooks which meet specific requirements (e.g. manage_beforeDelete and manage_afterAdd, which are useful for catalogues). As Sean mentioned, a good framework for doing this would be the workflow tool in the CMF, but you'll find there's a lot to get to grips with. There's a workflow tool which allows you to set states and transitions on objects; it also allows you to hook workflow to particular object methods (by wrapping the method with a proxy class). seb
