hi all, again :) how can I create an index in fields inherited by other classes?
example: class TimestampMixin(object):updated_on = Column(DateTime) # i wanted to create three indexes in this field, "updated_on", "updated_on.asc()" and "updated_on.desc()"
class SomeOtherClass(Base, TimestampMixin):
__tablename__ = 'some_table'
id = Column(Integer)
....
Index('ix_some_other_class_01', SomeOtherClass.updated_on)
Index('ix_some_other_class_02', SomeOtherClass.updated_on.asc())
Index('ix_some_other_class_03', SomeOtherClass.updated_on.desc())
I just want to avoid repetition, if possible :)
best regards,
richard.
