Hey i am trying to create a move line based on analytic account distribution like if the first line added by me has an analytic tag with a check box of analytic distribution marked true. I am confused in write or new method. Kindly help me with this

@api.onchange('analytic_tag_ids')
def analytic_account(self):
    for rec in self:
        if rec.analytic_tag_ids:
            for record in rec.analytic_tag_ids.analytic_distribution_ids:
                self.analytic_account_id = record.account_id
                self.price_subtotal = (rec.price_subtotal * record.percentage) / 100
            create_method = self.env['account.move.line'].create or self.env['account.move.line'].new
            inv_line = create_method({
                'name': self.name,
                'move_id': self.id,
                'account_id': rec.account_id.id,
                'analytic_tag_ids': rec.analytic_tag_ids,
                'analytic_account_id': rec.analytic_account_id.id
            })
            return inv_line

        else:
            self.analytic_account_id = False

Right now i am getting mode id error but i dont think i am still doing right. Kindly help
