[Zope] Recursive Display Of All Folder Items
Hi everyone, I am trying to get a dump of all the content currently in our zope server. Using DTML I was able to get the top level folders to display their content but I am unable to recursively display the contents of the sub-folders. This is the code I am using for my top level folders, where TV is the name of the folder I want to display. dtml-in TV.objectValues()dtml-var idbr/dtml-in My second attempt at displaying sub-folder content was the following: dtml-in TV.objectItems() id: dtml-var id,br type: dtml-var meta_typebr dtml-if meta_type=='Folder' dtml-in expr=objectValues(dtml-var id) id: dtml-var id,br type: dtml-var meta_typebr /dtml-in /dtml-if /dtml-in But that also fails. I searched the documentation and found a post about recursively calling the same function but that did not work as I get a excessive recursion error. Any help on this problem would be greatly appreciated. Thank you. -Francisco ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Any help on this problem would be greatly appreciated. objectValues is acquired on all objects, even non-folderish ones. Thus recursion never stops. You must ask for it explicitly: aq_inner.aq_explicit or something like that if I remember directly. --jcc -- Building Websites with Plone http://plonebook.packtpub.com/ Enfold Systems, LLC http://www.enfoldsystems.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

You must ask for it explicitly: aq_inner.aq_explicit or something like that if I remember directly. You shouldn't have to, if you're dealing with objects that inherit from OFS.SimpleItem.Item. This code is *supposed* to prevent infinite recursion: # This keeps simple items from acquiring their parents # objectValues, etc., when used in simple tree tags. def objectValues(self, spec=None): return () objectIds=objectItems=objectValues But of course, there's no requirement for everything to inherit from Item. All it takes is one persistent object that doesn't and you can get an infinite recursion. Another option, if you don't have a catalog handy, is to use ZopeFind(). See lib/python/OFS/FindSupport.py. (The docstring is unhelpful, but the method signature should give you a clue what to pass to it; or, look at the source for the Find page in the ZMI.) Call ZopeFind() on the folder you want to start your search at. -- Paul Winkler http://www.slinkp.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
