How to show current location on Google-Maps-for-Rails

I have the gem 'gmaps4rails' installed and currently the setup is to show the location:

<div style='width: 800px;'>
  <div id="map" style='width: 800px; height: 400px;'></div>
</div>

<script>
    handler = Gmaps.build('Google');
    handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){
        markers = handler.addMarkers(<%=raw @hash.to_json %>);
        handler.bounds.extendWith(markers);
        handler.fitMapToBounds();
        handler.getMap().setZoom(16);
    });
</script>

I would like to show the current location on the map as well. Any ideas on how to implement that?

Append current user location hash into your array of location hash and Rest will be handled by Gmap4Rails

def show
    @las = La.find(params[:id])
    @hash = Gmaps4rails.build_markers(@las) do |la, marker|
      marker.lat la.latitude
      marker.lng la.longitude
    end
    append_cur_location 
end 

def append_cur_location
  @hash << { :lat=>action[0], :lng=>action[1]}
end

def action
   @lat_lng = cookies[:lat_lng].split("|")
end

Extras: If you want separate image for current user location.use below

{ :lat=>12.9698, :lng=>77.7499, :picture=>{:url=>user_image_path, :width=>32, :height=>32} }
