ruby-on-rails - 将 InfoBox 自定义为 gmaps4rails

Question

你能帮我将 InfoBox 自定义为 gmaps4rails。我使用了已通过上传的标记的文档 https://github.com/apneadiving/Google-Maps-for-Rails/wiki/Change-handler-behavior

    @json = @weeds_map.to_gmaps4rails do |locations, marker|

        marker.infowindow  render_to_string(:partial => "info_window", :locals => { :object => locations})
        marker.picture({
                      :picture => "img/Store_pin.png",
                      :width   => 35,
                      :height  => 45
                     })

        marker.title "#{locations.title}"

end

不再显示。
