Wizards, scheduled actions, server actions and automation in code

TransientModel wizards, ir.cron jobs, server actions declared in modules, and writing robust batch jobs.

In this lesson

Wizards on TransientModel
Scheduled actions that behave
Server actions, automation and Odoo 20 agents

Key points

TransientModel + form target new; active_model/active_ids from context
ir.cron: idempotent, batched, logged; _trigger() to wake it
Server actions/automation shipped in XML call tested methods
Odoo 20: crons/automation can invoke AI agents with approval for writes

Real-world example

A nightly cron synchronised 20,000 products from a supplier API and timed out at limit_time_real, restarting from zero every night. Rewriting it to process 500 at a time, store the last synced ID, commit per batch and re-trigger itself finished the sync in 40 minutes.

Questions and answers

How do you close a wizard after its action?

Return {'type': 'ir.actions.act_window_close'}.

Why avoid cr.commit() in normal methods?

It breaks transaction atomicity and tests; reserve it for long batch jobs like crons.
