Filterrific is a Rails Engine plugin that makes it easy to filter, search, and sort your ActiveRecord lists:


  • Makes heavy use of ActiveRecord Scopes
  • ActionController helpers to shuttle filter params from ActionView forms to ActiveRecord based models, and to return matching records back from ActiveRecord to ActionView.
  • Form helpers to build powerful search and filter forms with ease.
  • Javascript assets to auto-submit filter form on change via AJAX.
  • Image asset to show a spinner in the Filterrific form when new records are being loaded via AJAX.
  • API option to use Filterrific with Rails API mode. Just use gem 'filterrific', require: 'filterrific_api' in your Gemfile.

Guidelines for submitting issues

Please post questions related to usage at StackOverflow under the filterrific tag.

If you think you've found a bug, or have a feature request, then create an issue here on Github. You'll make my job easier if you follow these guidelines:

  • Please keep in mind that I do this in my spare time. To you this software is free as in beer, to me it's free as in baby. I appreciate it if you first do everything you can on your own: read the detailed Filterrific documentation, look for similar issues on StackOverflow, search the internets, etc.
  • If you're stuck, give me sufficient context so that I have a chance to identify the issue:
    • what version of filterrific are you using? (look in your Gemfile.lock)
    • what version of Rails are you using? (look in your Gemfile.lock)
    • what version of Ruby are you using? (run ruby -v in your app root)
  • If you get an exception, include the entire stack trace, including the error message.
  • Include any relevant code snippets (your model, controller, and view code).
  • When pasting code, please use markdown code formatting. It will be much easier to read.
