Select2 search query and selection for Capybara

select2_helper.rb

# usage: 
# select2_choose("#some_element_id_with_select2_attached", :query => "Santa", :choose => "Santa Monica, California")
# NOTE: just make sure your 'choose' is unique in your results set
module Select2Helper
  def select2_choose(id, options)
    page.execute_script %Q{
    i = $('#s2id_#{id} .select2-offscreen');
    i.trigger('keydown').val('#{options[:query]}').trigger('keyup');
  }
 
     within(".select2-drop-active") do
       find(".select2-result-label", :text => options[:choose]).click
     end
  end
end

I'm getting "Circular dependency detected while autoloading constant Admin::Select2Helper (RuntimeError)" with either of the solutions.
