[Zope3-Users] Adding indexes to a Catalog tool subclass

[Tom Dossis]

I can add a tool which is a simple subclass of Catalog.
However if I try to add some index(es) in the constructor it fails with 
a NotYet error (see below).

Is there a simple way to achieve this?


from zope.app.catalog.interfaces import ICatalog
from zope.app.catalog.catalog import Catalog
from zope.app.catalog.text import TextIndex

class IFoodCatalog(ICatalog):
     pass

class FoodCatalog(Catalog):
     implements(IFoodCatalog)

     def __init__(self):
         super(FoodCatalog, self).__init__()
	#this fails
         #self['title'] = TextIndex('title', IFood)
