queries in the models.Instance context need to reference the table by name (fixed_ips) however queries in the models.FloatingIp context alias the tables out properly and return the data as fixed_ip (which is why you need to reference it by fixed_ip in that context).

Ideally we should probably consider adding a fixed_ip alias to the models.Instance query context so that the api code is consistent, but for now this should resolve the outstanding issues.
