GeoDjango has its own Feed subclass that may embed location information
in RSS/Atom feeds formatted according to either the Simple GeoRSS or
W3C Geo standards.  Because GeoDjango’s syndication API is a superset of
Django’s, please consult Django’s syndication documentation for details on general usage.
Feed 서브클래스¶Feed¶In addition to methods provided by the
django.contrib.syndication.views.Feed base class, GeoDjango’s
Feed class provides the following overrides. Note that these overrides
may be done in multiple ways:
from django.contrib.gis.feeds import Feed
class MyFeed(Feed):
    # First, as a class attribute.
    geometry = ...
    item_geometry = ...
    # Also a function with no arguments
    def geometry(self): ...
    def item_geometry(self): ...
    # And as a function with a single argument
    def geometry(self, obj): ...
    def item_geometry(self, item): ...
geometry(obj)¶Takes the object returned by get_object() and returns the feed’s
geometry. Typically this is a GEOSGeometry instance, or can be a tuple
to represent a point or a box. For example:
class ZipcodeFeed(Feed):
    def geometry(self, obj):
        # Can also return: `obj.poly`, and `obj.poly.centroid`.
        return obj.poly.extent  # tuple like: (X0, Y0, X1, Y1).
item_geometry(item)¶Set this to return the geometry for each item in the feed. This can be a
GEOSGeometry instance, or a tuple that represents a point coordinate or
bounding box. For example:
class ZipcodeFeed(Feed):
    def item_geometry(self, obj):
        # Returns the polygon.
        return obj.poly
SyndicationFeed 서브클래스들¶The following django.utils.feedgenerator.SyndicationFeed subclasses
are available:
GeoRSSFeed¶GeoAtom1Feed¶W3CGeoFeed¶참고
W3C Geo formatted feeds only support
PointField geometries.
