Solved: Geojason serializer is giving null geometry

Using Django
1

I’m having the same issue found in this question, though it was supposedly fixed in Django 1.9, so I thought maybe I’m doing something wrong.

I’m trying to serialize my geodjango data:

homes = serialize(
    "geojson",
    Home.objects.all(),
    geometry_field="point",
    fields=["address_point"],
)

I then go to print it out, and it shows that the geometry is null as follows:

{
   "type":"FeatureCollection",
   "crs":{
      "type":"name",
      "properties":{
         "name":"EPSG:4326"
      }
   },
   "features":[
      {
         "type":"Feature",
         "id":1,
         "properties":{
            "address_point":"SRID=4326;POINT (15.57385209377286 7.776164310995906)"
         },
         "geometry":null
      }
   ]
}

Further, when I try to access the data in my javascript (using django-geojson) and then log it to the console, the result is null. I believe the two issues are related.

{% load geojson_tags %}

var homes = {{ homes|geojsonfeature|safe }};
console.log(homes)

Would appreciate any insight into fixing this, thank you!

I have a partial answer: My geometry field should be address_point, so I now have:

def map(request):
    template_name = "map.html"
    homes = serialize(
        "geojson",
        Home.objects.all(),
        geometry_field="address_point",
        fields=[],
    )
    context = {"homes": homes}
    return render(request, template_name, context)

This now prints properly as having geomerty. However, I have yet to figure out how to get it to display on my map. Still working on that.

Fully solved. The rest of it wasn’t a django problem. But if you’re curious, this worked for me:

        let homes = JSON.parse('{{ homes|safe }}')
        L.geoJson(homes).addTo(map);

No need for any libraries other than leaflet itself.
