I had a dig around in the database - the subnets table has a foreign key reference to the networks table:
CONSTRAINT `subnets_ibfk_1` FOREIGN KEY (`network_id`) REFERENCES `networks` (`id`), which I believe would prevent the deletion of the network from the networks table until the subnet was deleted? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784342 Title: AttributeError: 'Subnet' object has no attribute '_obj_network_id' To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1784342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
