示例1: chatroomIndexMigration
# 需要导入模块: from MaKaC.plugins.base import PluginsHolder [as 别名]
# 或者: from MaKaC.plugins.base.PluginsHolder import isUsable [as 别名]
def chatroomIndexMigration(dbi, withRBDB, prevVersion):
"""
Migrating Chat Room index to new structure
"""
# The structure of the indexes is such that for each one self._data
# is a BTree and each node is referenced by the IndexBy___ designation,
# where ___ is the ID in question. Each node is then a TreeSet of
# ChatRoom or XMPPChatRoom objects originally orderded by ID, we need
# this to be ordered by title for effective searching / querying.
# The __cmp__ method has been altered to accommodate this new format,
# take each subnode, iterate through saving the current objects, clear the
# index and reinsert them - they will now be in the correct order.
