[Rails] Relationship problem, newbie problem, need help!!
Hey all I seem to be having some problems with my relationship between a few tables... If i then run the following query in mysql, i get the data i want. How do i do this in rails relationships and models? select * from shop_addresses left join shops on shops.id = shop_addresses.shop_id left join styles on styles.id = shops.style_id where shop_uri = ''127.0.0.1'' Cheers!!
