Re: GeoDjango - Difficulty placing vector marker from DB
There are many ways to fix the projection issue, this is one (probably not
the best)
On your view code:
sites_list=sites_list.transform(900913)
Best,
Ariel.

GeoDjango - Difficulty placing vector marker from DB
Hey,
Having great trouble getting geodjango/openlayers to display vector
markers propery - everything I try positions the sample point off the
coast of Africa (no matter if I change the vector position in
geoadmin). Here's what I'm working with - any help appreciated!:
var lon = -2.900;
var lat = 54.160;
var zoom = 6;
var map, baselayer;
var wkt_f = new OpenLayers.Format.WKT();
var v_markers = [{% for site in sites_list
%}wkt_f.read('{{ site.point.wkt }}'){% if not forloop.last %},{% endif
%}{% endfor %}];
var marker_style = {'strokeColor' : 'green', 'fillColor' : 'green',
'fillOpacity' : 0.9, 'pointRadius' : 6}
for (var i = 0; i < campsite_markers.length; i++){v_markers[i].style =
marker_style;}
function init(){
var options = {
'projection' : new OpenLayers.Projection("EPSG:900913"),
'units': "m",
'maxResolution': 156543.0339,
'maxExtent': new
OpenLayers.Bounds(-20037508,-20037508,20037508,20037508),
'controls':[new OpenLayers.Control.Navigation(), new
OpenLayers.Control.ZoomPanel()],
'numZoomLevels' : 20,
};
// base map
map = new OpenLayers.Map('map', options);
// - MS Virtual Earth Layer
baselayer = new OpenLayers.Layer.VirtualEarth("Virtual Earth",
{ 'type': VEMapStyle.Street, "sphericalMercator": true});
map.addLayer(baselayer);
// Controls for the map
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.addControl(new OpenLayers.Control.MousePosition());
var layermarkers = new OpenLayers.Layer.Vector("markers");
layermarkers.addFeatures(v_markers);
// Vector Layers for the sites
var LonLat = new OpenLayers.LonLat(lon, lat).transform(new
OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());
map.addLayer(layermarkers);
map.setCenter(LonLat, zoom);
}
