Renaming objects (changing object ids)

Introduction

This page tells how to rename Plone content objects and change their ids.

• This only concerns URL path ids
• Unique ID (UID) is not affected
• Title can be changed using setTitle() etc. mutator

Renaming objects

OFS interface has facilities to rename objects

• http://svn.zope.org/Zope/trunk/src/OFS/interfaces.py?rev=105745&view=auto
• manage_renameObject(oldid, newid) for one item
• manage_renameObject([oldid, oldid2], [newid, newid2]) for rename many items
• Products.CMFPlone.PloneFolder overrides manage_renameObject() to have hooks to reindex the new object path

Warning

Security warning: “Copy or Move” permission is needed on the object by the logged in user.

Warning

New id must be a 8-bit string, not unicode. The system might accept values in invalid format.

Example how to rename object lc to have -old suffix:

id = lc.getId()
if not lc.cb
parent = lc.aq_parent
parent.manage_renameObject(id, id + "-old")

These checks performed before rename by the manage_renameObject():

if not lc.cb_userHasCopyOrMovePermission():
    print "Does not have needed permission"
    return

if not lc.cb_isMoveable():
    # This makes sanity checks whether the object is
    # properly connected to the database
    print "Object problem"
    return

Warning

Testing warning: Rename mechanism relies of Persistent attribute called _p_jar to be present on the content object. By default, this is not the case on unit tests. You need to call transaction.savepoint() to make _p_jar appear on persistent objects.

Unit testing example:

import transaction


self.portal.invokeFactory("Document", doc")
doc = self.portal.doc

# Make sure all persistent objects have _p_jar attribute
transaction.savepoint(optimistic=True)

# Call manage_renameCode()...
