I have this function that calculates qty_incoming, but there is an outgoing_qty field that I want to calculate with the same function and not to create separate function for its calculation. how can I do this?

 _columns = {
            '
            'incoming_qty': fields.function(_product_inc_out_qty, type='float',
                digits_compute=dp.get_precision('Product Unit of Measure'),
                string='Incoming'
            ),
            'outgoing_qty': fields.function(_product_inc_out_qty, type='float',
                digits_compute=dp.get_precision('Product Unit of Measure'),
                string='Outgoing'
            ),
        }

function:

def _product_inc_out_qty(self, cr, uid, ids, field_names=None, arg=False, context=None):
        if context is None:
            context = {}

        res = {}
        for move_id in ids:
            move = self.browse(cr, uid, move_id, context=context)

            res[move.id] = move.product_id.incoming_qty or 0.0
        return res



if I do something like this, then I get error TypeError: float() argument must be a string or a number


def _product_inc_out_qty(self, cr, uid, ids, field_names=None, arg=False, context=None):
        if context is None:
            context = {}

        res = {}
        vals = {
            'outgoing_qty': 0.0,
            'incoming_qty': 0.0,


        }
        for move_id in ids:
            move = self.browse(cr, uid, move_id, context=context)
            vals['outgoing_qty'] = move.product_id.qty_available or 0.0
            vals['incoming_qty'] = move.product_id.incoming_qty or 0.0
            res[move.id] = vals

        return res

Hi,

In the sales module you can see similar sample in which for multiple field values are computed using the same function, have a look at those function and you can update your case.


See the sample:

amount_tax = fields.Monetary(string='Taxes', store=True, readonly=True, compute='_amount_all')
amount_total = fields.Monetary(string='Total', store=True, readonly=True, compute='_amount_all', track_visibility='always', track_sequence=6)

Compute function: 

@api.depends('order_line.price_total')
def _amount_all(self):
    """
    Compute the total amounts of the SO.
    """
    for order in self:
        amount_untaxed = amount_tax = 0.0
        for line in order.order_line:
            amount_untaxed += line.price_subtotal
            amount_tax += line.price_tax
        order.update({
            'amount_untaxed': amount_untaxed,
            'amount_tax': amount_tax,
            'amount_total': amount_untaxed + amount_tax,
        })


You can see same code in v8 here in this file: https://github.com/odoo/odoo/blob/8.0/addons/sale/sale.py
