Hi there. I'm wondering if it's possible to obtain the bom list from another model. I wish to display them in the stock_picking model, and I've tried to use 'fields.related' but I could only get certain values from mrp_bom and mrp_bom_list, thus am pretty unclear on how should I link it to the bom list components. I have the product_id in the current model, and I understand that I have to somehow use this field to get its bom list, but to no avail.

'test_relational_field' : fields.related('product_id', 'id',type="integer",relation="mrp.bom")

Any pointers are very much appreciated. Thanks!
