Draw polyline

[DonIvanCorleone]

Hi all,

i am sorry but after a couple of hours searching for a solution i came here to ask you. I haved trouble to draw polylines, on my map. All I want to show are my start and end markes and the route from start to end using polylines.

here is my code:

Controller

@result = Gmaps4rails.destination(start_end, options={}, output="pretty") @steps = Array.new @result.each do |r|

      r["steps"].each do |step|

        @steps << { :lng => step["start_location"]["lng"], :lat => step["start_location"]["lat"] }

      end

  end

View

<%= gmaps({

"map_options" => {"type" => "ROADMAP", "center_longitude" => @locations.first[:lng], "center_latitude" => @locations.first[:lat], "zoom" => 4, "auto_adjust" => true, "language" => 'de'},
"markers" => { "data" => @locations.to_json },
"polylines" => { "data" =>  @steps.to_json  }
})
%>

As already said, markers recieved by the locations array are completely fine, polylines from steps does not show anything at all. I am really desperate. Does anyone have an idea what is goind wrong?

By the way: I use the newest version (2.0.0pre)

Any help appreciated

It seems your data is not properly formatted.

Thanks a lot for your response,

I already tried your example, but unfortunately it did not work. At least I do not see the polyline, but I do see the markers on the map. Much more interesting is, if I use the :direction option and specify :from and :to, I do see the markers AND the polyine (!) which connects both. I really have no idea what is going on and why the beahviour is somehow strange. Do you have another idea for me? Any help appreciated!

Many thanks in advance.

Cheers Ivan

Please provide your data, creating fixtures is too long.

I feel so sorry. I just figured out what happened. After updating the gem version i forgot to update the javascripts. I really forgot all the time. Thanks and sorry again for the inconvenience. This ticket can be closed.
