[Zope-dev] [ZPT] Zope 3 ZPTs in Zope 2
Hi, I have a working implementation for Zope 3 ZPTs within Zope 2. It is currently implemented through a new class ZPT which implements the same functionality as Products.PageTemplates.ZopePageTemplate. I am currently thinking about the migration to the new implementation. Would it be possible to perform an in-place migration using setstate() when replacing the ZopePageTemplate implementation with the prototype code from my ZPT class?

Are there different object-attributes in both classes? If not, you could simple replace with the same old class name. If there are (you would have to know them anyway to do the __setstate__ approach) I'd like an approach with an upgrade script (similar to 'stale Python Scripts') better. Buts just me ;-) Regards Tino ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

The Z3 ZPT implementation seems to use the same attrs. So I could just replace the class implementation. Some first quick tests show that there is no further need for a migration..it just works :-) -aj pgpHUtnauZTqQ.pgp Description: PGP signature ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
