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.
Guys, I'm a newbie, still learning and quiet often I have a dilemma how should I do this or that :)
So if would you like to explain and enlighten it a bit for me please.
cr.execute("""SELECT sum(qty) from stock_quant where location_id = %s""" % obj.id)
tot_qty = cr.fetchall()
how to do the same using old API ?
self.pool.get(stock.quant)..search(cr, uid, [('usage', '=', 'production')], context=context)
like that ?
and how should it look like in new API ?
self.env['stock.quant'].search([('usage', '=', 'production')])
or more generic:
self.env['model.name'].search([('variable', 'operator', 'value')])
at search you can also limit the recordsets:
self.env['model.name'].search([('variable', 'operator', 'value')], limit=1)
self.env['model.name'].search([('variable', 'operator', 'value')]).name
and much more.
is new api. If you're using odoo8 or 9 I'd stick with the new API style.
On a side note: If you want to add or modify records and you've got computed fields, stay away from using queries as computed fields will not be calculated using raw queries.
