[Zope-dev] Using Python script to create ZClass instances

[Bjorn Stabell]

After hours of fiddling around, I've already given up Python methods,
but I can't even instantiate MySubZclass via External Methods?!?!?

	MyProduct . MyZClass . MySubZClass


1. folder.manage_addProduct['MyProduct'].MyZClass.MySubZClass_add(id)
	-> AttributeError for MySubZClass_add

2.
folder.manage_addProduct['MyProduct'].propertysheets.methods['MySubZClas
s_add'](id)
	-> NameError on MySubZClass (at least it gets to the constructor
method)

I really think one of the major pains of Zope is just instantiating
objects...  It's HELL hard, and NOT intuitive.

Hi there,

Im having problems using Python script to create a ZClass instance from
a ZClass that's inside of another ZClass.  I have this addMyObject
Python script as constructor script for "Scriptable Type Information"
type object (CMF):

	## Script (Python) "addMyObject"
	##bind container=3Dcontainer
	##bind context=3Dcontext
	##bind namespace=3D
	##bind script=3Dscript
	##bind subpath=3Dtraverse_subpath
	##parameters=3Dfolder, id
	##title=3D
	##
=09
folder.Control_Panel.Products.MyProducts.MyObjects.MyObject_add(id)

	# folder.manage_addProduct('MyProduct')... doesn't work either

	item =3D getattr(folder, id)

	return item

MyObjects is a ZClass that contains MyObject.  The error I get is:

	Zope error
	Error type AttributeError=20
	Error value MyObjects

There should be some explanation somewhere how to access resources
inside of Control_Panel, but I fail to find it.  Creating objects is
very confusing and difficult at times...

Bye,
