Adding a computed field, whose value depend on 2 other fields from 2 others models

Question

I'm trying to add a computed field from the *UI* (*x_my_field*) to the model *sale.order *whose value is computed based on 2 other fields, let's say *field1* from the model *sale.order.line* and *field2* from the model *mrp.bom.line : *
*x_my_field* =* sale_order_line.field1* * *mrp_bom_line.field2 *
But i can't figure out how to add the correct dependencies !!! to make it work.
All fields are of type float.
Any advice or help !

Are you editing odoo base? Editing odoo base is not recommended.
I would recommend creating another module that depends on mrp and sale (define it on the manifest).

Then you can inherit 'sale.order' and change it as you see fit.
Hope that helps.
