I was setting up an admin for someDjangomodels that had a PointField the other day, and I ran into an issue that took a little digging to figure out.

How do you set default_lon, default_lat, and default_zoom for a PointField in the django admin page using GISModelAdmin class? With the following code the admin page loads correctly, but with the default location in Europe. model.py from django.contrib.gis.db import models class Enclosure(models.Model): location = models.PointField() name = models.CharField(max_length=15) admin.py from .models import Enclosure @admin.register(Enclosure) class EnclocusreAdmin(GISModelAdmin): pass I've tried the following code to try to set default lat, lon for the widget. However doing this results in no map displayed for the PointField on the admin page. admin.py from .models import Enclosure @admin.register(Enclosuer) class EnclosureAdmin(GISModelAdmin): gis_widget_kwargs = {'attrs': { 'default_lon': 50, 'default_lat': 100,}} The relevant Django code is class GISModelAdmin(GeoModelAdminMixin, ModelAdmin): pass class GeoModelAdminMixin: gis_widget = OSMWidget gis_widget_kwargs = {} def formfield_for_dbfield(self, db_field, request, **kwargs): if ( isinstance(db_field, models.GeometryField) and (db_field.dim < 3 or self.gis_widget.supports_3d) ): kwargs['widget'] = self.gis_widget(**self.gis_widget_kwargs) return db_field.formfield(**kwargs) else: return super().formfield_for_dbfield(db_field, request, **kwargs) class OSMWidget(OpenLayersWidget): """ An OpenLayers/OpenStreetMap-based widget.

I'm currently learning to program with Django and its spatial extension, GeoDjango. I use Posgresql and Leaflet. I use models that I defined manually and that contain PointField fields. I also use models automatically generated by the ogrinspect command, which contain PointField, MultiLineStringField, and MultiPolygonField fields. The models automatically generated and data importing into the database using GeoDjango's LayerMapping tool must be manipulable via Django user interfaces (e.g., to be able to modify them, for example, by adding or removing a field from the model, performing calculations, etc.). Is it necessary to use geoserver or is geodjango sufficient to map this data?
