class Feed [source]
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
