Hello, I have two tables which looks like
class CI_OnlineResource(object): def __init__(self): super(CI_OnlineResource, self).__init__() self.applicationProfile = None self.function = None class MO_OnlineResource(CI_OnlineResource): def __init__(self): super(MO_OnlineResource, self).__init__() self.function = None self.applicationProfile = None the two classes contains the same attributes (function, applicationProfile) because in "my" specifications is required that 1) MO_OnlineResource.applicationProfile is a String 2) MO_OnlineResource.applicationProfile is an ENUM of String type So at this moment I have mo_onlineresource_table = Table('mo_onlineresource', metadata, Column('mo_onlineresource_id', Integer, Sequence('mo_onlineresource_id_seq'), primary_key=True), Column('function', MO_OnLineFunctionValue.db_type(), nullable=False), Column('applicationProfile', MO_ApplicationProfileValue.db_type(), nullable=False), Column('mo_onlineresource_type', String(30), nullable=False), extend_existing=False,) ci_onlineresource_table = Table('ci_onlineresource', metadata, Column('ci_onlineresource_id', Integer, Sequence('ci_onlineresource_id_seq'), primary_key=True), Column('applicationProfile', TEXT()), Column('function', CI_OnLineFunctionCode.db_type()), extend_existing=False,) where "db_type" is a @classmethod I use to define the ENUM type. mapper(CI_OnlineResource, ci_onlineresource_table) mapper(MO_OnlineResource, mo_onlineresource_table.join(ci_onlineresource_table)) Obviously running such script I obtain the following error sqlalchemy.exc.InvalidRequestError: Implicitly combining column mo_onlineresource.applicationProfile with column ci_onlineresource.applicationProfile under attribute 'applicationProfile'. Please configure one or more attributes for these same-named columns explicitly. Anyone has an idea how get out of this situation? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
