Hi Leticia. It looks like your container overrides __init__ and,
rather than deferring to the SampleContainer.__init__, you are trying
to set the __data value in your own class. If you are not familiar
with the magic pseudo-private '__*' behavior in Python, maybe you
should read up on it. The immediate fix, though, is to change your
current SampleContainer __init__.
If now it looks something like this:
class SampleContainer(BTreeContainer):
# ...
def __init__(self):
# ...
self.__data = self._newContainerData()
# ...
then delete than instantiation and instead do this:
class SampleContainer(BTreeContainer):
# ...
def __init__(self):
# ...
super(SampleContainer, self).__init__() # this replaces the
self.__data line
# ...
That should hopefully clear it up.
If you need to change what is made as the data object, override
_newContainerData (although that's where the btree mix in does its
work!).
