Django 4.1: New Features for Handling Geometries
Django 4.1 brings two new features for handling geographic geometries; allowing developers to create valid and canonical geometries more easily:
GEOSGeometry.make_valid()returns a valid representation of a geometry. Unless the geometry is already valid, then the geometry is returned without changes. The function is very similar to
GEOSGeometry.normalize()returns the canonical, or standardised, representation of a geometry. The method now accepts the optional
clonekeyword indicating that the normalisation must not change the geometry and instead return a new geometry object.
Additionally, support for GDAL 2.1 and PostGIS 2.4 has been removed, and the Django Admin’s
OpenLayersWidget is now deprecated.
