If you just get all the relevent categories in @categories then for each category accessed via something like @categories.each do |category| then you can use category.sub_categories and then for each of those the posts in exactly the way suggested in your original code. There is no need to do anything special in the query, just fetch the relevant categories. By the way could you not top post please, it makes it difficult to follow the thread. Insert you reply at appropriate points in the previous message. Thanks.
