I've got two classes (which I'm simplifying here for the sake of an easier
demonstration).
class WorldTakeOver(sqlobject):
Events = MultipleJoin('Event',joinColumn="OptimizationId")
LastEventDate = DateTimeCol(default=None)
CurrentStatus = UnicodeCol(default=None)
Notes = UnicodeCol(default=None)
def AddEvent(self,event_name,desc=None):
et = EventType.byName(event_name)
e = Event(OptimizationId=self.id,EventTypeId=et.id,Description=desc)
class Event(sqlobject):
WorldTakeOverId = ForeignKey(WorldTakeOver',cascade=False)
EventDate = DateCol(default=datetime.now())
EventTypeId = ForeignKey("EventType",cascade=False)
Description = UnicodeCol(default=None)
def _init(self,*args,**kwargs):
"""
When we create an Event, we have to update the WorldTakeOver object
so it knows the LastEventDate and its current status, if any.
"""
wto = WorldTakeOver.get(self.WorldTakeOverId)
wto.LastEventDate = self.EventDate
if self.debug: print "New event. Status:",self.Type.Status
if self.Type.Status:
opt.CurrentStatus = self.Type.Status
if self.debug: print "Updated WorldTakeOver status:",wto.CurrentStatus
I'm having trouble accessing my Event objects. What's strange is that there
are no issues with creating events in the first place. However, both (for
example)
w = WorldTakeOver.get(123)
w.Events
and
e = Event.get(123)
throw the same error:
File "<stdin>", line 1, in ?
File
"/usr/local/lib/python2.4/site-packages/SQLObject-0.7.4-py2.4.egg/sqlobject/main.py",
line 920, in get
val._init(id, connection, selectResults)
File "WorldTakeOver.py", line 253, in _init
wto = WorldTakeOver.get(self.WorldTakeOverId)
File "<string>", line 1, in <lambda>
File
"/usr/local/lib/python2.4/site-packages/SQLObject-0.7.4-py2.4.egg/sqlobject/main.py",
line 997, in _SO_loadValue
self._SO_writeLock.release()
AttributeError: 'Event' object has no attribute '_SO_writeLock'
I'm not using any locks on these objects at all, so I'm not sure why I'm
encountering a writeLock when I try to read the object but not when I write
it. Is there anything I'm overlooking here?
Thanks,
Molly
