The column_prefix wasn't being honored when the mapper checked for existing names, this is fixed in trunk r5839. But also, don't create instances of the object before the class is mapped. In particular, it's bad form to create tables and mappers inside of class methods. Create class-level constructs like tables and mappers at the module level, in the same scope in which you create your classes. > > mf2 = Foo.Foo() # ok, let's create a new one. > # AttributeError: 'Foo' object has no attribute > '_sa_instance_state' > myfoo._phone = '555-1212' # > > if __name__ == '__main__': > orm.clear_mappers() > f = Foo.Foo() > fs = FooStore() > fs.map(f) don't create instances of the object before the class is mapped. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
