That's amazing! Believe it or not I was mocking a very similar thing (besides rails). And select2. What made me rethink was the heavy dependencie on using datatables and mobile compatibility. Am I worrying too much and datatables.net "just works"?
Thanks! That's a really good point - and it's currently one of the codebases biggest weaknesses. I use DataTables EVERYwhere. They're fantastic - I have tons of places where I need to show thousands of records, so I use server side processing for pagination, filtering, sorting, etc. However, they don't look good on mobile, and the responsive tables plugin is not the greatest. What I actually do (for now) is wrap the table in Twitter Bootstraps .table-responsive class, which basically creates a viewport for the table on mobile. You scroll left/right to see hidden columns. Works pretty well. Long term, I'm not sure what I am going to do as there are no other table plugins with as rich a featureset and I prefer not to write my own.
