Hello Odoo Community. 

I'm creating a field which calculate avg price sale order using this variables in Odoo v14:

for record in self:
        record['x_studio_orden_promedio'] = record.total_invoiced / record.sale_order_count

However when I try to see this field in action I get a divided zero error cause they are some clients that haven't make their first order.

How can I create an exception that print a result on this formula? Does custom fields can have exceptions?

Thanks in advance.
