Brian, I can get data on the maps with no problem. It is just making it change when the user selects something. If you are trying to get data on a map, I have a handy way for you to do it. This is only for your template. You will have to find a way to geocode everything ahead of time. GeoDjango can do this or something like GeoPy can also. There are also snippets on Django snippets that have different ways doing it. Sorry if you already know how to do this and I just misunderstood. This worked for me because I already had the lat and long for what I was doing.
# In your template do this. The gmap will load in the div with the id of map. # You can style the div to be different sizes. You can also get a smaller map # control from google. <head> <script src="http://maps.google.com/maps? file=api&v=2&key=GOOGLE KEY GOES HERE!" </head> <body onunload="GUnload()"> <div id="map"> <script type="text/javascript"> //<![CDATA[ // A function to create the marker and set up the event window // Dont try to unroll this function. It has to be here for the function closure // Each instance of the function preserves the contends of a different instance // of the "marker" and "html" variables which will be needed later when the event triggers. function createMarker(point,html) { var marker = new GMarker(point); GEvent.addListener(marker, "click", function() { marker.openInfoWindowHtml(html); }); return marker; } // Display the map, with some controls and set the initial location var map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GMapTypeControl()); // Starting position of map and starting zoom level map.setCenter(new GLatLng (26.979910721880167,-82.16880798339844),11); // Set up markers with info windows {% for model in object_list %} var point = new GLatLng({{ model.latitude }}, {{ model.longitude }}); var marker = createMarker(point,'') map.addOverlay(marker); {% endfor %} //]]> </script> </div> </body> On Feb 4, 11:20 pm, Brian Neal <bgn...@gmail.com> wrote: > Hi - > > I'm working on a very similar problem (displaying data on a Google > map).
