hi amigos , if someone get hand ,
how can i get the value of field standard_price from product.product class i want to add , a new field in account.invoice.tax Class
'standard_price': fields.function(_get_standard_price , string='standard price', store=True)
if someone can help
thanks .
You must browse the product record and get the field you want. In account.invoice.tax you haven't got a direct relation with product.product because account.invoice.tax is a many2many table.
so how can use , standard_price
i have try this ligne
produit = pro_obj.browse(cr, uid, line.product_id) price = 0.0 price = (line.price_unit - produit.standard_price)
but , i have an error message :
TypeError: unsupported operand type(s) for -: 'float' and 'NoneType'
Hi,
Change code like this :
price = ((line.price_unit or 0.0) - (produit.standard_price or 0.0))
