Hi, I got a folderish python product with the following method: def SKU(self): """ Return our SKU for the catalog """ return self.sku The problem is that when objects contained in instances of this product are cataloged, they acquire the SKU method, so they also get the sku property. That is bad. So what I need is something like this: def SKU(self): """ Return our SKU for the catalog """ if (I was acquired): return None else: return self.sku But I can't figure out how to do that. Help?
