'root' is probably a misprint. If you're using the bin/zopectl script that comes with zope 2.7.x, you should substitute 'app' instead of 'root'. '/path/to/container' is a generic example. Substitute the path to any container you're interested in. The author of the recipe cannot predict what paths are of interest to you. Only you can know that. > Therefore I used fsrefs.py and got information like > > oid 0x030571 Products.CMFCore.ActionInformation.ActionInformation > last updated: 2005-03-14 08:20:34.643177, tid=0x35BE85493CF9666L > refers to invalid object: > oid 0x0304fa object creation was undone: > 'Products.CMFCore.Expression.Expression' > > For this oid I get > > > python > Python 2.4 (#1, Jan 14 2005, 00:24:33) > [GCC 2.95.3 20010315 (release)] on sunos5 > Type "help", "copyright", "credits" or "license" for more information. > >>> from Zope.Startup.run import configure;configure('/etc/zope.conf') > >>> from Zope import app > >>> app = app() Note, there is a shortcut to the above: you can just run the command ./bin/zopectl debug > >>> from ZODB.utils import p64 > >>> from ZODB import POSException > >>> obj = app._p_jar[p64(0x030571)] > >>> print obj.getId() > view > >>> print obj.bobobase_modification_time() > 2005/03/14 09:20:34.643 GMT+1 > >>> print obj.meta_type > simple item that's kind of unusual. Most Products have a more descriptive meta_type. Sounds like somebody wrote a subclass of OFS.Item.SimpleItem and did not bother to provide a proper meta_type in their code. Some grepping of source code in your Products directory might tell you what this thing really is. > >>> print obj.__ac_local_roles__ > None > > Could anybody tell me, how I can delete this object from Data.fs? > Will obj.manage_delObjects(id) do the job for me? What parameters > do I have to give to the programm? No, that would delete a sub-object of obj. If you want to delete obj itself, you have to find its parent folder first. You have found out an id ('view'), a mod time ('2005/03/14 09:20:34.643 GMT+1'), and a (weird) meta_type ('simple item'). That should give you some good clues for finding where this object lives, and thus find its parent folder. Once you know that, you can follow the zopelabs recipe. Unfortunately, there is no way to just ask a raw object for its physical path. You can call obj.getPhysicalPath() but it not tell you anything useful on a raw object (one directly loaded from _p_jar) because it is lacking its acquisition context. -- 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 )
