Saving ActiveAdmin filters between requests

This shows one technique for preserving filters on index pages for ActiveAdmin resources, without having to patch the ActiveAdmin core.

It restores any previously-used filters whenever the index page is rendered for a resource, unless the current request is an actual application of new filters. It also properly handles the clear-filters button (via a synchronous Ajax request that happens immediately before the normal filter form processing).

Yes, it's a bit of a hack, but it has worked well for me so far.

module ActiveAdmin
  module Views
    class IndexAsTable < ActiveAdmin::Component
      include CustomHelper
      
      def column_select resource, attr, list
        val = resource.send(attr)

        html = _select list, val, { "attrs" => %{
                                                    data-path='#{resource.class.name.tableize}'
