Django Admin - Leaflet：以编程方式向现有地图添加标记

Question

models.py:

class Point(models.Model):
    point = models.PointField()

admin.py:

admin.site.register(Point, LeafletGeoAdmin)

一切都很好。

但是，我想在按下按钮时手动添加指向管理地图的指针。

templates/admin/myapp/point/change_form.html:

{% extends "admin/change_form.html" %}
{% block after_field_sets %}
<input type="button" id="startWatchButton" value="Show marker" />
{% endblock %}

javascript:

$(function() {
    $("#startWatchButton").click(function() {
        var mymap = <How to select the initialized django map?>
        var marker = L.marker([51.5, -0.09]).addTo(mymap);
    });
});

如何 select 已经存在并已初始化的 django 管理映射？

You can use the Leaflet API as usual. There are two ways to grab a reference on the just initialized map and options.

...
<script type="text/javascript">
    window.addEventListener("map:init", function (e) {
        var detail = e.detail;
        ...
        L.marker([50.5, 30.5]).addTo(detail.map);
        ...
    }, false);
</script>
