Hi all, I'm working on a product that renders treemenu's for websites. Now I have to get an initlevel as starting point for my menu. But the function getInitLevel doesn't work in the __init__ method, because acquisition doesn't work here. Following Casey's example at www.zopelabs.com/cookbook/995468614 I got to the following: def manage_addSiteNav(self, id, title=''): """Add a SiteNav to a folder.""" self._setObject(id, SiteNav(id, title, self.getId(), self)) if self.REQUEST is not None: return self.manage_main(self, self.REQUEST) def __init__(self, acquiredObjectName, container, id, title='', initlevel= 0): """initialise a new instance of SiteNav""" self = self.__of__(container) # Create an acquisition wrapper acquiredObject = getattr(self, acquiredObjectName) # Acquire the object self.id = id self.title = title self.initlevel = self.getInitLevel() def getInitLevel(self): """returns the initlevel""" initlevel = 0 parent = self while 1: if hasattr(parent,'aq_parent'): parent=parent.aq_parent initlevel = initlevel + 1 else: break return initlevel - 1 But what is acquiredObjectName in this context?
