Hi,

Please change your Python code as below and try it again:for records in model.search([]):
  if records.state == 'sent':
    records.write({'state':'sale'})

You can also able to create a scheduled action:

if you create the schedules action as exactly as same as above it will only trigger one time, because the number of calls is '1'. If you want to execute daily or at all times according to your trigger time you can make the number of calls to '-1'

Hope it helps
