search for: cuisines_restaurants

I''ve got a Cuisine and a Restaurant model, with a habtm. One thing I want to do is find all the cuisines that have at least one restaurant associated with them. Right now I''m using the following SQL query: SELECT DISTINCT(cuisines.*) FROM cuisines, restaurants, cuisines_restaurants WHERE cuisines.id = cuisines_restaurants.cuisine_id AND restaurants.id = cuisines_restaurants.restaurant_id AND restaurants.approved_at IS NOT NULL That''s working fine. I''d really like to make this a pure AR thing though so I can use the rest of the AR options. Any tips on how...
