It is sometimes necessary to modify the context on a recordset to get the desired results from a method call or the desired value for a computed field.

This recipe shows how to read the stock level for all product.product models in a given stock.location.

Getting ready

This recipe uses the stock and product addons. For our purposes, here is a simplified version of the product.product model:

    _name = 'product.product'
    name = fields.Char('Name', required=True)
    qty_available = fields.Float('Quantity on Hand',
                                 compute='_product_available')
    def _product_available(self...
