Re: [Zope] accessing object from a list constructed in init.py

22 Jul 2006

      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.

---myClass.py---
import Acquisition

class class1(Acquisition.Explicit):
    ''' a simple class with some attributes and methods'''
    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):
    ''' a second simple class with some attributes and methods'''
    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.__of__(self))
            i=i+1

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

----myZclass.py-----
from zope.interface import implements
from zope.schema.fieldproperty import FieldProperty
from OFS.SimpleItem import Item, SimpleItem
from persistent import Persistent
import myClass
from interfaces import *
import Acquisition

class Zclass2(SimpleItem,myClass.class2,Acquisition.Explicit):
    '''a simple zope class that inherits from my class'''
    implements(Izclass2)
    def __init__(self,tmpID='',tmpTITLE=''):
        '''non empty docstring'''
        cm = myClass.class2.__init__(self)
        return cm.__of__(self)

    def myZclass(self):
        cm = myClass.class2()
        return cm.__of__(self)

I'm doing some work with Five and have an aquisition related issue.
first, zope is zope 2.9.3
The trouble is with accessing the attributes of objects stored in the
number property in class2.
class2 must inherit from ExtensionClass.Base (or some subclass, like 
Acquisition.Explicit) in order to be acquisition aware.
