Class Factory?

gistfile1.py

TAG_TYPES = ["location", "category"]
class Tag(db.Model, BaseEntityMixIn,
          IgnoreDeletionMixIn):
    __tablename__ = "tag"

    name = db.Column(db.Unicode(255), index=True)
    type = db.Column(db.Enum(*TAG_TYPES, native_enum=False), index=True)
    __mapper_args__ = {'polymorphic_on': type}

g = globals()
for t in TAG_TYPES:
    def __init__(self, t=t, **kwargs):
        kwargs["type"] = t
        Tag.__init__(self, **kwargs)

    cls_name = t.capitalize()+"Tag"
    cls = type(cls_name, (Tag,), {'__tablename__':None,
                                  '__mapper_args__': {'polymorphic_identity' : t},
                                  '__init__': __init__})
    g[cls_name] = cls

SAWarning이 거슬려서 type()을 쓰게끔 대대적으로 변경...
