Chomh maith le modhanna a sholáthraíonn an:class: Django.Contrib.Syndication.Views.Feed bunaicme, soláthraíonn rang ``Feed ``GeoDjango na foriompaithe seo a leanas. Tabhair faoi deara gur féidir na sáruithe seo a dhéanamh ar bhealaí éagsúla:

Code

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): ...

Tógann sé an réad ar ais ag ``get_object () ``agus filleann sé an geoiméadrachta*feed's* ar ais. De ghnáth is cás “Geosgeoiméadracht” é seo, nó féadann sé a bheith ina tuple chun pointe nó bosca a léiriú. Mar shampla:

Code

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)Link to this definition#

Socraigh é seo chun an geoiméadracht do ghach* míre* sa bheatha a thabhairt ar ais. Is féidir seo a bheith ina shampla ``Geosgeoimetry', nó tuple a léiríonn comhordú pointe nó bosca teorainneacha. Mar shampla:

Code

class ZipcodeFeed(Feed):
    def item_geometry(self, obj):
        # Returns the polygon.
        return obj.poly
