While upgrading a Zope 2.1.0 beta installation recently to 2.1.3, I discovered that a recent change made to 'DT_Var.py' rendered DTML expressions like <dtml-var this url> and &dtml.url-this; inoperative. I had been relying on them for a default action url on my forms (in DTML methods). Especially the entity reference syntax is quite a nice abbreviation for the more explicit <dtml-var "this().absolute_url()"> which still continues to work.
The enclosed fix simply acknowledges that 'this' isn't a ZODB namespace object but a method encapsulating python 'self' and thus always needs to be invoked. I'm not quite on the top of things why the previous behavior was changed in the first place (Jim? Anyone?).
I'll file this to the Collector if there's no objection by you. Copyright to the patch is hereby transfered to Digital Creations to be used freely.
Breaking access to this().abosulte_url() in the above way was probably not intentional. Yes, please put it in the Collector, as it may get lost otherwise. -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------
