Dear Colleagues, 

odoo is in version 17. how can I add an auto action to check availability using auto actions?

I try: 

# Available variables:

#  - env: environment on which the action is triggered

#  - model: model of the record on which the action is triggered; is a void recordset

#  - record: record on which the action is triggered; may be void

#  - records: recordset of all records on which the action is triggered in multi-mode; may be void

#  - time, datetime, dateutil, timezone: useful Python libraries

#  - float_compare: utility function to compare floats based on specific precision

#  - log: log(message, level='info'): logging function to record debug information in ir.logging table

#  - _logger: _logger.info(message): logger to emit messages in server logs

#  - UserError: exception class for raising user-facing warning messages

#  - Command: x2many commands namespace

# To return an action, assign: action = {...}

action = {

    record.action_assign()

}

but now work.
