what's the best way to check and retrieve the polymorphic identity of a
mapped class?
I'm using:
*pi = cls.__mapper_args__.get('polymorphic_identity')**
**if pi:**
** # rest of the code**
** ...*
I'm just wondering if there's a shortcut or a better way to achieve
this, since I'm not fond of using *__variables__* :)
best regards,
richard.
