I am facing a problem while tring to develop a product.I want to use an attribute of the parent of my object but the problem is that i want to use it in the __init__ method.The problem occurs due to the fact that i am tring to use aquisition over the object while it is not "ready" because __init__ isn't over yet.(for example there is no attribute self.aq_parent meaning that aquisition can't be used yet ). In particular i have a folder containing a database connection and in the same folder i am tring to create an instance of my object.In it's __init__ method i want to contact the database and create a table for example.The problem is that the database connection can't be found because as said before there is no aquisition yet. So if i want to do something while constructing the object using a function that requires an attribute of the parent what should i do? Thanx

You must pass the container to __init__ and create a wrapper manually, like so: def __init__(self, container): wrapped = self.__of__(container) wrapped.some_acquired_attr... There are several examples of this in the Zope source. I think Catalog.py (in the ZCatalog product) is such a beast, it needs to acquire a vocabulary when it is instantiated. hth, -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>
