How to access data from foreign models via foreign-key inside .xml-views ?

I want to access data from foreign models via foreign-key from inside .xml-views.

Concrete example: account.invoice.tree

account.invoice model "knows" partner_id as foreign key. I also want to display res.partner.cust_id inside account.invoice.tree. From inside .rml reports, I can simply do o.partner_id.cust_id and the field desired is displayed without needing to inherit the appropriate python class. Can this be achieved like that from within .xml view files and if yes, how?

A view can only display data from a single model.

You can create a new model, which combines information from two others, and is defined by a SQL statement.

Thank you very much! I will try that. I had another idea: Inherit account.invoice model and add a function field for every additional field from foreign model I need. These fields could have store="False" property, as their values are already available and needn't be entered/stored. Would this approach work, too?
