Thanks. I've filed an issue <https://bitbucket.org/zzzeek/sqlalchemy/issue/3185/more-than-one-level-of-abstract-concrete> at Bitbucket.
A follow-up question: Why are abstract base classes not present in the declarative class registry? Or is there another way to get all the mapped classes besides iterating over Base._decl_class_registry? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
