|
This sitemap object initializes on a feed dictionary (as would be passed
|
|
to `django.contrib.gis.views.feed`) and a slug dictionary.
|
|
If the slug dictionary is not defined, then it's assumed the keys provide
|
|
the URL parameter to the feed. However, if you have a complex feed (e.g.,
|
|
you override `get_object`, then you'll need to provide a slug dictionary.
|
|
The slug dictionary should have the same keys as the feed dictionary, but
|
|
each value in the slug dictionary should be a sequence of slugs that may
|
|
be used for valid feeds. For example, let's say we have a feed that
|
|
returns objects for a specific ZIP code in our feed dictionary:
|
|
|
|
feed_dict = {'zipcode' : ZipFeed}
|
|
|
|
Then we would use a slug dictionary with a list of the zip code slugs
|
|
corresponding to feeds you want listed in the sitemap:
|
|
|
|
slug_dict = {'zipcode' : ['77002', '77054']}
