Iam using gmaps4rails to show gmaps in my application.iam getting the map pointa right but iam unable to differentiate the current location and nerby locations in my map.my idea  is to use different markers for two locations i did it in the following way but it didnt worked for me

my controller

def profile
   @googlemaplocation=Location.
find_by_id("#{params[:clinic_id]}")
   
    @json1 = @googlemaplocation.to_gmaps4rails do |locations, marker|

  marker.picture({
                  :picture => "http://www.google.com/mapfiles/dd-start.png",
                  :width   => 32,
                  :height  => 32
                 })
  end

    @neargooglemaplocation=@googlemaplocation.nearbys(10)
    @json2= @neargooglemaplocation.to_gmaps4rails do |locations, marker|

  marker.picture({
                  :picture => "http://www.google.com/mapfiles/dd-start.png",
                  :width   => 32,
                  :height  => 32
                 })
  end
   
    @json = (JSON.parse(@json1) + JSON.parse(@json2)).to_json
   
  end

my view

<%= gmaps(:markers => { :data => @json } ) %>

what should i do if i want to display two different markers on the same map

Thanks & Regards
