I am trying to add a bunch of school boundary files into the database. The boundary files are inconsistent. They are processed by
DataSource as either
MultiPolygon is fairly simple using Generalizing Polygons to MultiPolygons in GeoDjango?, but the conversion does not work for
class School(models.Model): boundaries = models.MultiPolygonField() --- from django.contrib.gis.geos import Polygon, MultiPolygon from django.contrib.gis.geos.collections import GeometryCollection ds = DataSource('school_boundaries.aspx') feature = ds geom_geos = feature.geom.geos if isinstance(geom_geos, Polygon): geom_geos = MultiPolygon(geom_geos) elif isinstance(geom_geos, GeometryCollection): geom_geos = MultiPolygon(GeometryCollection) #This does not work school = School(boundaries = geom_geos) school.save()
Is there some way to convert
MultiPolygon in GeoDjango?
