This solution for sorting data on rails index actions does NOT use ajax. Sometimes sorting with ajax is nice but often it is not actually as user friendly; breaking the browser back button, etc…
Disclaimer 1: this code is probably using all kinds of ruby anti-patterns :) - but it is a very simple implementation and so I just went with it…
Disclaimer 2: the title of the post might be a little miss leading as you can use this with or without the will_paginate plugin. In my case I am using it with the will_paginate plugin - and I highly recommend it!
put this file in your rails lib directory /lib/sort_index.rb
in your controller code, set up the SortIndex::Config (you can have more than one if you have multiple actions that need to support sorting
then in your view code render your table headers using the sort object
Does not support the following:
- additional attributes on the anchor tags
- additional attributes on the table header tags
- additional query string parameters - might add this later, would be nice for search results
