Hi guys,
I am getting the following error when i try to add a model instance to the session.

Error:
TypeError: raise_first_error() takes exactly 3 arguments (2 given)

Raised when:
models = odm.Router('redis://localhost:6379?db=0')
models.session().add( my_object)

Stdnet Version:
0.8.2

Python:
2.7

Redis:
2.9.0

Thanks
