GeoDjango has its own Feed subclass that may embed location\ninformation in RSS/Atom feeds formatted according to either the Simple\nGeoRSS or W3C Geo standards. Because GeoDjango’s syndication API is a\nsuperset of Django’s, please consult Django’s syndication documentation for details on general usage.
Feed SubclassLink para este cabeçalho#In addition to methods provided by the\ndjango.contrib.syndication.views.Feed base class, GeoDjango’s\nFeed class provides the following overrides. Note that these overrides\nmay be done in multiple ways:
from django.contrib.gis.feeds import Feed\n\n\nclass MyFeed(Feed):\n # First, as a class attribute.\n geometry = ...\n item_geometry = ...\n\n # Also a function with no arguments\n def geometry(self): ...\n\n def item_geometry(self): ...\n\n # And as a function with a single argument\n def geometry(self, obj): ...\n\n def item_geometry(self, item): ...\nTakes the object returned by get_object() and returns the feed’s\ngeometry. Typically this is a GEOSGeometry instance, or can be a tuple\nto represent a point or a box. For example:
class ZipcodeFeed(Feed):\n def geometry(self, obj):\n # Can also return: `obj.poly`, and `obj.poly.centroid`.\n return obj.poly.extent # tuple like: (X0, Y0, X1, Y1).\nSet this to return the geometry for each item in the feed. This can be a\nGEOSGeometry instance, or a tuple that represents a point coordinate or\nbounding box. For example:
class ZipcodeFeed(Feed):\n def item_geometry(self, obj):\n # Returns the polygon.\n return obj.poly\n
