Autorefreshing fields

v2.40.0

We have introduced autorefresh attribute for the fields in the form and tree views. This attribute is used to refresh the field automatically. This is useful when you want to update the field value based on the other fields in the form.

For example, you have a progress field in the form view, and you want to update it, you can set the autorefresh attribute to 1.

<field name="progress" widget="progressbar" autorefresh="1"/>

class SomeWizard(osv.osv_memory):
    _name = 'some.wizard'


    @classmethod
    def update_progress(cls, database, uid, wiz_id, context=None):
        db, pool = pooler.get_db_and_pool(database)
        wiz_obj = pool.get(cls._name)
        with db.cursor(readonly=True, isolation_level='repeatable read') as cr:
            for progress in range(0, 101):
                wiz_obj.write(cr, uid, [wiz_id], {
                    'progress': progress
                }, context=context)
                time.sleep(0.1)
        return True


    def start(self, cr, uid, ids, context=None):
        threading.Thread(
            target=SomeWizard.update_progress,
            args=(cr.dbname, uid, ids[0], context),
