i put the original html source code in the folder source_code, i want to refactor html to gsp, and use asset-pipeline to manage css/js, but i failed. can you help me and show me the best practice of using asset-pipeline. there are just two pages need refactor, dashboard.gsp and the alerts_btns.gsp, there are different js and css files, i think one application.js and one application.css will be huge if i put all together.
