In Wagtail GeoLocation Widget how to set a Default location ( and set zoom )

 To set the default map location in the wagtailgeowidget package, you can define the GEO_WIDGET_DEFAULT_LOCATION setting in your Django settings file.

Here is an example of how to do this:

GEO_WIDGET_DEFAULT_LOCATION = {"lat": 50.5230, "lng": -4.6558}

This will set the default map location to the coordinates 50.5230° N, 4.6558° W (Bodmin, Cornwall, United Kingdom).

The GEO_WIDGET_DEFAULT_LOCATION setting should be a dictionary with keys 'lat' and 'lng' representing the latitude and longitude, respectively. The values should be float values.

You can also set the default map location dynamically based on the value of a field in your model by defining a callable as the value of the GEO_WIDGET_DEFAULT_LOCATION setting.

Here's an example of how to do this:

from django.conf import settings

def get_default_location():
    # Code to retrieve default location from model goes here
    return {"lat": 50.5230, "lng": -4.6558}

GEO_WIDGET_DEFAULT_LOCATION = get_default_location

This will set the default map location to the value returned by the get_default_location function.
