rodrigoolmo / geoPolymorphicManager.py

Created December 5, 2013 13:33

If you use GeoDjango your models require a GeoManager model manager. If you use django-polymorphic for inheritance in Django your models require a PolymorphicManager model manager. What if you need both functionalities? Then use this manager: GeoPolymorphicManager

	from django.contrib.gis.db import models
	from django.contrib.gis.db.models.query import GeoQuerySet
	from polymorphic import PolymorphicManager
	from polymorphic.query import PolymorphicQuerySet


	class GeoPolymorphicQuerySet(GeoQuerySet, PolymorphicQuerySet):
	'''
	QuerySet used in GeoPolymorphicManager.
