I've changed my code a bit, adding the docstring, Persistent to all
classes and
__allow_access_to_unprotected_attributes__ = 1 to all classes. Still,
I recieve the same error.
I have changed the code so _attribute1a is a single instance of class1
instead of a list of containing multiple instances of class1 and I
can access the attributes of the object without issue.
Are the objects automatically unwrapped when added to a list? is
there a way around this?
I can send the code again if need be.
so here is the code again, this time with only the single object in
attribute1a.
--myClass.py--
import Acquisition
from persistent import Persistent
class class1(Acquisition.Explicit,Persistent):
''' a simple class with some attributes and methods'''
__allow_access_to_unprotected_attributes__ = 1
attribute1 = 'attribute 1'
attribute2 = 'attribute 2'
_number = ''
def __init__(self,number2):
'''simple init for the class'''
self._number=number2*3
def method1(self):
'''return a string methd1'''
mthd1 = 'methd1'
return mthd1
def method2(self):
''' return a string methd2'''
mthd2 = 'method2'
return mthd2
def _get_number(self):
return self._number
number = property(fget=_get_number)
class class2(Acquisition.Explicit,Persistent):
''' a second simple class with some attributes and methods'''
__allow_access_to_unprotected_attributes__ = 1
_attribute1a = []
attribute2a = []
def __init__(self):
'''create a list of class1 objects in attribute1a'''
#i=1
#while i < 5:
# obj = class1(i)
# self._attribute1a.append(obj)
# i=i+1
self._attribute1a = class1(5)
def method1a(self):
'''instantiate class1 as object and return object usable by
zope'''
obj = class1(5)
return obj.__of__(self)
def method2a(self):
'''returns class1.method1()'''
c1m1 = class1.method1()
return c1m1
def get_attribute1a(self):
#if self._attribute1a != []:
#i = len(self._attribute1a)
#j = 0
#while j != i-1:

#else:

attribute1a = property(fget=get_attribute1a)
attribute1b = property(fget=method1a)
attribute2b = property(fget=method2a)

Ok, thank you for that.
I can create the list of objects from the __of__(self) attribute
without the wrapper error now,
but I still cannot access that attribute through zope.
Here is my code again, along with my zope content.
Another thing I've missed, class1 isn't persistent, but you store
instances in Zclass2.attribute1a. This can explain the "can't pickle"
error.
