Hi everyone,


I'm beginner on Odoo12 and I'm trying to update a data in the database using custom module, but it's not working.

Thanks for your help.


class IrSequence(models.Model):
    _inherit = "ir.sequence"

    @api.model
    def _update_sequence(self):
        cr = self._cr
        cr.execute("SELECT id FROM ir_sequence WHERE name = 'BILL Sequence' LIMIT 1")
        sequence_data = cr.fetchone()

        if sequence_data:
            cr.execute(
                "UPDATE ir_sequence SET name='INV Sequence', implementation='standard', prefix='INV/%(range_year)s/', use_data_range=0 WHERE id = %s",
                (sequence_data[0]))
            return True

It looks like you're trying to update the sequence numbering. You can do that through a configuration settings rather than writing a custom module.

It's under the Settings -> Technical -> Sequences & Identifiers -> Sequences menu. Typing in Sequences on the search bar on the home page should bring it up.

Also note that it is usually easier, and safer, to update data through the API instead of directly through the SQL database.

Thank for your answer. So It's more difficult and dangerous to do it through a custom.
