Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
Sorry if this is super basic, I am almost new with python.
So, basically I am passing an
ID to a function and I need to get the record just before the one with the
ID I am passing from a table.
This is my function
def get_prev_period(self,period_id): if period_id: period_list = self.pool.get('sim.periods').browse(self.cr, self.uid, period_id) current_id = period_list.id #Now I need to get the ID just above current_id return 0
So, basically I need to get the
ID just above the
current_id. I am not able to do
current_id - 1 because that might no be the case.
Any tips will be much appreciated! Thanks!
You need to execute your manual query on postgres database table,
def get_prev_period(self,period_id): if period_id: result= self.cr("""SELECT id FROM table_name WHERE id < %s ORDER BY id DESC LIMIT 1""", [period_id]) result = self.cr.dictfetchall() print result # holds the one row data current_id = result['id'] return 0
