Hi,
Over the last month or so, I've rather wonderfully managed to corrupt my
ZODB with artifacts of my Currency class that no longer exist.
This is due to:
(i) moving the module to a different package (twice)
(ii) renaming the module
(iii) changing it's inheritance hierarchy (having removed all Zope-awareness
from class has caused loads of setstate issues in regard to either
__basicnew__ not found, AttributeErrors, and problems with non-derivation
from AcquireImplicitWrapper)
I now desperately need to write a parser to convert all of these nasties to
ZCurrency types. I've come up with the following ExternalMethod - whereby
I've defined a __currency__ attribute in each obselete incantation's product
(Currency object's are used in the spirit of DateTime rather than within
ObjectManager containment structures):
from Acquisition import aq_base
from Products.BastionBanking.ZCurrency import ZCurrency
def repair(container, counter=0):
for (k,v) in container.__dict__.items():
if hasattr(v, '__currency__'):
setattr(container, k, ZCurrency(v._currency, v._amount))
counter += 1
for object in container.objectValues():
for (k,v) in object.__dict__.items():
if hasattr(v, '__currency__'):
setattr(object, k, ZCurrency(v._currency, v._amount))
counter += 1
if hasattr(aq_base(object), 'objectValues'):
repair(object, counter)
return counter
However, it doesn't seem to find anything to convert. Does anyone have any
ideas?
TIA, Alan
