ActiveAdmin Bootstrap

This is a rough proof of concept.

There will be broken things.

Comments are welcome.

Installation

# This file extends and overrides parts of the ActiveAdmin DSL and internals
# in order to provide support for automatically displaying and editing images,
# which in our infrastructure are stored as URLs whose column names end in "img".
# Since this file will be reloaded frequently in the development environment,
# all operations done at load time (class_eval's, etc.) MUST be idempotent.

ActiveAdmin::Views::TableFor.class_eval do

  def img_column(col_sym=:img, title="Image")
    column title, sortable: false do |obj|

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.

Usage

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}'

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.
