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.
I have to call sale_order fields.function names _amount_all from another button function for less the discount amount from total amount when validating sale order.Please help me in this situation.
In Odoo 8 and above.
One cannot trigger the computational fields without the change in values of its dependent fields.
Say in case of SaleOrder, "_amount_all" method is depended on the field value price_subtotal present in its child class i.e. in SaleOrderLine, So unless and until the value of price_subtotal is changed, the function will not be triggered. which is actually a good functionality, because it avoids unnecessary triggers and writing values into the database.
Now coming to your requirement, if am not wrong you have a discount_field in SaleOrder and upon specifying a value you want the same to be reflected in Total Amount of SaleOrder.
So why not inherit _amount_all in your custom module and concatenate the discount_field into @api.depends as shown below.
@api.depends('discount_field') def _amount_all(self): super(SaleOrder, self)._amount_all() for order in self: order.amount_total -= order.discount_field
Am sure this way you can achieve your requirement, but if you still wanted to trigger the computation field, and if you using Odoo 8 then all you need to do is add recompute = True in the context while calling write method as below.
context = dict(self._context, recompute=True)
Note: In Odoo 9, recompute doesn't work.
