There is however no way how to use ST_MakeValid to simply repair GEOS Geometry. Note that there is also now comparable function in the GEOS library itself (not counting something simple like buffer(0)). This missing feature is also subject to Stackoverflow questions, like: https://stackoverflow.com/questions/45631855/equivalent-of-postgis-st- makevalid-in-django-geos/45633779 Attached patch implements new PostGISOperations method called "make_valid", that can be run from implementation code simply by: {{{ from django.db import connection repaired_geos_geometry = connection.ops.make_valid(some_goes_geometry) }}} -- -- Ticket URL: <https://code.djangoproject.com/ticket/30649#comment:1> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
