title: Rails ActiveRecord query sorting 2 models?
body: <p>This is my specific question. I need to display in view only the records from bboys table that match the criteria. The criteria is: records based on stars count for 'dimension: originality' in descending order. rateable_id: 3 in rates table is same as id: in bboys table. Any advice is greatly appreciated! I am new to querying with AciveRecord, so any info I could build on would be great. </p>
