Below is the class I use for this. Just call
attribute_cleaner(self,'_v_my_attribute') before assigning to
_v_my_attribute, and it will be cleared at the end of the ZODB
transaction.
I wonder if this is generally useful enough to go in the ZODB
distribution?
class attribute_cleaner:
def __init__(self,client,attr):
self.client = client
self.attr = attr
get_transaction().register(self)
def ClearCache(self,*args):
try:
delattr(self.client, self.attr)
except AttributeError:
pass
except KeyError:
pass
tpc_finish = tpc_abort = abort = abort_sub = ClearCache
def tpc_begin(self,transaction,subtransaction=None): pass
def commit(self,object,transaction): pass
def tpc_vote(self,transaction): pass
def commit_sub(self,transaction): pass
