Hi all
To fix the error I must change the __init__ of the BTreeContainer class to
the follow:
"""
class persistent_test(BTreeContainer):
implements(Ipersistent_test)
def __init__(self):
BTreeContainer.__init__(self)
self['un_padre'] = Padre('Lety','Campanilla')

Any idea about store object and list of objects?
This way is the right way?
I'm not sure if I have understood your problem correctly, but here is
what you probably could do:
For Root: inherit from Persistent and call __init__ of parent class
(btw: using super(CurrentClass, self) is the recommended way to do that)
class Root(Persistent):
def __init__(self):
super(Root, self).__init__()
self.rootIndex = RootIndex()
For list: use PersistentList instead of list.
For Leave and RootIndex: inherit from Persistent as well (and remember
to call super(...).__init__ if you define own constructor)
Regards,
Alek
Thanks in advanced

Hi all
Resume:
I want to store persistent data in the zope database. I must have an object
that store others object inside it, including list of objects, etc. I want
that when I create the root object automatically create object inside it.
Example of python class:
"""
class Leave:
name = u""
(...)
class RootIndex:
index_list = []
(...)
class Root:
name = u""
rootIndex = None
leave_list = []
def __init__(self):
self.rootIndex = RootIndex()
