Where do controller methods for rails_admin custom actions go?

Question

I created a custom action in RailsAdmin using https://github.com/sferik/rails_admin/wiki/Custom-action, but I'm unsure where I would put my controller methods within the custom action and if I use a form what would be the path to call those controller methods?

Answer 1

Here's an example of a custom action I'm using for pdf (project here):

require "rails_admin_pdf/engine"

module RailsAdminPdf
end

require 'rails_admin/config/actions'

module RailsAdmin
  module Config
    module Actions
      class Pdf < Base
        RailsAdmin::Config::Actions.register(self)

        register_instance_option :member do
          true
        end

        register_instance_option :controller do
          Proc.new do
            report = "#{@object.class.to_s.demodulize}Report".constantize.new
            send_data report.to_pdf(@object), :filename => "#{@object.class.to_s.demodulize}_#{@object.id}.pdf", :type => "application/pdf"  
          end
        end
      end
    end
  end
end

So, to answer your question, the controller method goes inside the lib/rails_admin_*custom_action_name*.rb module. I'm not sure I understand the second part of your question regarding form submission. You can check out another example of a custom action with form submission here.
