how to show different markers for current location and nearby locations in gmaps4rails

Hai guys,

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

It seems this is the third time that you have asked this in as many
days. The fact that no-one has replied probably means no-one knows
the answer. There is no point just asking the same question again and
again.
