It is a cheatsheet. I created it to bookmark working solution, because it's kind of rare encountered.

ActiveAdmin.register_page 'CustomPage' do
 menu parent: "Main"

 content do
 count = SomeModel.count
 render partial: 'admin/custompage/upload_form', locals: {count: count}
 end

 page_action :import, method: :post do
 imported = Import.new(params[:file].path)
 imported.import
 redirect_to admin_custompage_path, notice: "Imported #{imported.element_count}."
 end
end

h2 Import XML
h3
 ' Total:
 b= count

= form_tag(admin_custompage_import_path, multipart: true) do
 = file_field_tag 'file', required: 'required'
 = submit_tag 'Upload', name: nil
