django-geojson 4.1.0

Serve vectorial map layers with Django

django-geojson

See the documentation for more information.

django-geojson is a set of tools to manipulate GeoJSON with Django >= 3.2:

• (De)Serializer for (Geo)Django objects, querysets and lists

• Base views to serve GeoJSON map layers from models

• GeoJSON model and form fields to avoid spatial database backends (compatible with django-leaflet for map widgets)

CHANGELOG

4.1.0 (2024-05-13)

• Drop Python 3.7, Django 3.2. Support Python 3.11 and 3.12, Django 4.2 and 5.0. #123

4.0.0 (2022-10-17)

• Drop support for Python < 3.7 / Django < 3.2

• Remove jsonfield dependency in favor of django.db.models.JSONField

  WARNING : This can break your migration. jsonfield used to create a text column for your json data when running ‘makemigrations’. However, django.db.models.JSONField creates a json column using database-backend specific column types (ie jsonb on postgresql). As such your model field that used to be a text column is now a jsonb column.
