Best way for two models in one controller?

Hi everyone,
My question is about following: I have two tables, products and products_description. First holds the general information like price and article number of the products, the description the textual description for each language, so 1:n (like 1 product can have many descriptions in different languages).
So I have controller "Products" and two models for each table.
When I like to query ALL product info in one call.... like general information plus description and details, what do I do best?
