Question

我使用django-geoposition来管理我的地理数据。在我的home.html：

<!-- Add Google Maps -->
<script>
function myMap() {
  {% for posts in post_list %}
  myCenter=new google.maps.LatLng(34.8402781,135.592376);
  var myLocation=new google.maps.LatLng({{posts.position.latitude}},{{posts.position.longitude}});
  var mapOptions= {
    center:myCenter,
    zoom:7, scrollwheel: true, draggable: true,
    mapTypeId:google.maps.MapTypeId.HYBRID
  };
  var map=new google.maps.Map(document.getElementById("googleMap"),mapOptions);
  var marker = new google.maps.Marker({
    position: myLocation,
    title:'{{ posts.title }}',
    draggable: false,

  });
  marker.setMap(map);

  {%endfor%}
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCB1CA2DoITfJoFY4HWTLTxH4Avx7QWWqA&callback=myMap"></script>

但它只是在地图上显示了第一个帖子的制作者。我猜for循环不起作用。我不知道该怎么办。我将不胜感激任何帮助！

我看到以下错误：
- Javascript：你必须为标记做循环而不是整个地图渲染javascript代码我建议你使用基于类的视图（在本例中为ListView）。

使用地理定位的Django标记
