Hi, Does someone know how to create interfaces with circular references? E.g.: class IHusband(Interface): wife = Object(schema=IWife) class IWife(Interface): husband = Object(schema=IHusband) What's the suggested solution to this problem? Perhaps I should modify the classes after they are declared, e.g.: class IHusband(Interface): pass class IWife(Interface): pass IHusband.wife = Object(schema = IWife) IWife.husband = Object(schema = IHusband) Or is there a better solution?
I don't think dot notation works for schema fields, you should use mapping notation. Otherwise I had a similar problem some time ago and coded it similarly, although slightly simpler:
class IHusband(Interface): wife = Object(schema= Interface) class IWife(Interface): husband = Object(schema= IHusband) IHusband['wife '].schema = IWife Regards, Markus Kemmerling ___________________ Medical University Vienna Core Unit for Medical Education P.O.
