    Beginner Help - Trying to get a map to start.

      Hello I just started using RhoMobile today not ever have using Ruby before so I'm not sure if I'm having trouble because of that or because I'm not setting it up right. I tried following the tutorial word-for-word to add a google map to one of my pages. On the index I changed the link to call map_it in the controller.



      <div data-role="content">

          <ul data-role="listview">

            <li><a href="<%= url_for(:action => :map_it) %>">Go to Map</a></li>





      And added this below the login method in the controller.js file- this is where I assumed it would go.



      def map_it

              map_params =


                      :settings => {:map_type => "hybrid", :region => [30, -80, 0.2, 0.2], :zoom_enabled => true, :scroll_enabled => true, :shows_user_location => false, :api_key => ""},

                      :annotations => 


                              :latitude => 30,

                              :longitude => -80,

                              :title => "Here is a marker",

                              :subtitle => "Marker!",

                              :url => "#"




              redirect :action => :index




      The only changes I made in the above are that I took out the api_key (I don't know if it's necessary since the google maps api for js doesn't require it anymore) and the url for the annotation (I don't have one yet, I just want to get the map started).


      Now when I click the Go to Map button on the index it says "Error Loading Page" but I don't know why. Was I supposed to install a google maps gem or something?


      Also a side question- why are some variables aren't prefixed (map_params), some are prefixed with the at sign (@params) and some are prefixed with a colon (:map_type and :action).

          Hi Micah,

          Do you see some error in Javascript console or Rholog.txt? If so can you paste them here.

          Also, have you managed to run the sample app https://github.com/rhomobile/rhodes-system-api-samples/tree/master/app/GeoLocation successfully on your emulator?

              Ok so I downloaded the entire application and tried to run it but got this failure on compile.
