How to do selective rollback using python maapi api ?

[abdelseaudi]

I was able to test https://community.cisco.com/t5/nso-developer-hub-discussions/commit-and-rollback-usint-action-python-code/m-p/4145068.

I used transaction.load_rollback(rollback_nr), and it works.

I tried also _ncs.maapi.load_rollback, and _ncs_maapi.load_rollback_fixed, and they work.

However, it rolls back the configuration up to the rollback number given to the function

How can I do a selective rollback instead ?

Hi,
There is an action to do rollbacks. Here is a python function to invoke that action. You will need a write transaction to create ‘root’, and you need to apply that transaction.

def rollback_id( root, rollback_number):
apply_rollback_file = root.rollback_files.apply_rollback_file
args = apply_rollback_file.get_input()
args.fixed_number = rollback_number
args.selective.create()
apply_rollback_file(args)
