show IP location on google map

I am trying to get user location from IP address as the user logs in into my django app. but don't know how to do it exactly. I am using GeoIP for 开发者_开发技巧this purpose. my question is how to write a view for this purpose and how can I show the location of the IP on a google map.

I guess you are talking about how to plot markers, cause GeoIP looks to provide you the latitude and longitude. For plotting markers tutorial you can look here.

For v3 Api of google maps.

Showing geoip on a google map you can use the free geoip service on http://freegeoip.net/json/ and plot the map points as below:

    var geoLocations = getLocations();
    var center = getCenter();
    var map = new google.maps.Map(document.getElementById('googlemap'), 
    {
      zoom: 1,
      center: new google.maps.LatLng(center[0], center[1]),
      mapTypeId: google.maps.MapTypeId.SATELLITE 
    });
    var markerInfo = new google.maps.InfoWindow();
    var pointMarker, i;
    // Go through the location array...
    for (i = 0; i < geoLocations.length; i++) 
    { 
        // Add the marker.
        pointMarker = new google.maps.Marker(
            {
                position: new google.maps.LatLng(geoLocations[i][1], geoLocations[i][2]),
                map: map
            });
        // Add the information window when clicking the marker
        google.maps.event.addListener(pointMarker, 'click', (function(pointMarker, i) 
        {       
            return function() 
            {
                markerInfo.setContent(geoLocations[i][0] + ' -> ' + geoLocations[i][3]);
                markerInfo.open(map, pointMarker);
            }
        })(pointMarker, i));

        // Zoom on double click
        google.maps.event.addListener(pointMarker, 'dblclick', (function(pointMarker, i) 
        {       
            return function() 
            {
                map.setZoom(17);
            }
        })(pointMarker, i));            
    }
