Re: [Zope] tree and dtml-with only not working for me

Andy Heath wrote: [ preventing acquisition within a tree-tag ] After going through the archives my third (and hopefully better tested) trial with this :-) In your Extensions directory create an external python method with this code: def prev_acqu(self, prop): if self.__dict__.has_key(prop): return getattr(self,prop) else: return '' add it with the id prev_acqu (or anything else you like better) to a folder in the acquisition path. In your tree code do: <dtml-var "prev_acqu('rubbish')"> If you choose a different id, of course you have to take it here, too. Apologies again for jumping into this thread without exactly verifying my code examples yesterday, thomas
