Hello, I come back from a long travel in outer space... :-) I lost all my archives, and searching eegroup is a pain (still looking after 1 hour...) I remember one of you explaining how to get SQL Method result from a tree tag. At the time this clever guy did this, zope was not even 2.0.0alpha 1, so he couldn't add a howto page to www.zope.org Could someone explain how to do this. I've got something like this: sql_get_children(parent): SELECT key, parent, name FROM table WHERE <dtml-sqltest parent type=int> <dtml-comment>The top-level is parent=0</dtml-comment> view_hierarchy: <dtml-tree expr="sql_get_children(parent=0)" branches_expr="sql_get_children(parent=parent)"> <dtml-var name> </dtml-tree> However, it does not work :-( It raise a NameError on 'parent', which I guess it could get from the sql method result any idea? Regards, Jephte CLAIN minf7@educ.univ-reunion.fr PS: please answer me directly since I'm not prepared yet to read 50+ message a day being on the list :-) If possible, send the message to minf7@educ.univ-reunion.fr instead of ava@dde974.equipement.gouv.fr since that #@$ Exchange don't known what a reply-to adresse is...
