Below I've written a function that could be helpful for you:

def get_quantity_at_location(self,cr,uid,lid,p):
    ls = ['stock_real','stock_virtual','stock_real_value','stock_virtual_value']
    move_avail = self.pool.get('stock.location')._product_value(cr,uid,[lid],ls,0,{'product_id':p})
    return move_avail[lid]['stock_real']

Basically, you are using the function _product_value() from the 'stock.location' class, and taking the 'stock_real' of the return statement.

Hope this helps!


Thanks it also good solution, I will test it.

Hello Zahin,

This method will return the quantity on hand on the location which is passed on method for passed product as argument on method.

def quantity_by_loc(self, product_id, location_id, context)

     #if you can't access context from method as argument than you can define here.
     product_obj = self.pool.get('product.product')
     qty = 0.0
     if context is None:
        'states': ['done'],
        'what': ('in', 'out'),

    avail_product_details = product_obj.get_product_available(cr, uid, product_id, context=context)
    if avail_product_defails.values():
        qty = avail_product_defails.values()[0]
    return qty

I hope this will helps you.

There is a function in product.product called get_product_available. You can get the stock value in location by passing the location id in context. So you can modify your code as:

def product_qty_by_location(self, cr, uid, product_id, warehouse_stock_location, context=None):
    if context is None:
        context = {}
    product_pool = self.pool.get('product.product')
    context.update({'states': ('done',), 'what': ('in', 'out'), 'location': warehouse_stock_location})
    result = product_pool.get_product_available(cr, uid, [product_id], context=context)
    qty = result.get(product_id, 0.00)
    return qty

You can also get the stock level of product based on warehouse by passing warehouse_id insted of location_id as:

context.update({'states': ('done',), 'what': ('in', 'out'), 'warehouse': <warehouse_id>})

context is frozendict, hence cannot be modified. I think it has become more complex in odoo 8

I think one can also use the select statement

select sum(product_qty) from report_stock_inventory where product_id = p1 and location_id = w1 and state = 'done'

where p1 is the product id , w1 is the location id, this gives you the actual stock

if you needed the unallocated stock only you can drop the "state='done'" from the where clause

I also get one alternate solution.

    def product_qty_by_location(self, cr, uid, product_id, warehouse_stock_location, context=None):
        sql = """select ((select sum(product_qty) from stock_move where product_id = %s and state in ('done') and location_dest_id = %s group by product_id) - (select sum(product_qty) from stock_move where product_id = %s and state in ('done') and location_id = %s group by product_id) ) as total;""" % (product_id, warehouse_stock_location, product_id, warehouse_stock_location)
        return cr.fetchall()[0][0]

This gives me exact qty on hand by location. It fulfill my requirement.


How would one use these functions in the following context:

    def _get_raw_qty(self, cr, uid, ids, field_name, args, context=None):
        res = {}
        lid = 13
        for record in self.browse(cr, uid, ids,context=context):
            pid = record.product_id
            lid = 13

            qty = self.product_qty_by_location(cr, uid, pid, lid) # I need to get the qty in a specific location per record.
            res[record.id] = 3.0
        return res
