Open Stack

The information in the Nova DB should provide by a client API interface. Quantum should use the client and invoke the API call.

Hi-


While going through the SQLALchemy of the Quantum, I was struck on how to Access the NOVA DB tables from Quantum SQLAlchemy.

Can any one guide me on How to query the tables of the NOVA DB from the Quantum SQLAlchemy. I have seen that the querying in SQLAlchemy in NOVA and Quantum, is with Models which are the table definitions.

How can we query the NOVA DB tables from the Quantum SQLAlchemy like wise cross DB querying from every Module of Openstack?

Please help me understand the approach in this regard.

Thanking you
