hierarchical navigation by date in my external view

[frank h.]

Hello,
I want my external view to feature a "date hierarchy", as the one that
can be configured in the admin application. This is really one
fantastic feature, I could use it all over the place in my
applications! If only it was more readily accessible to the layman...
But I understand that with the new-admin branch merged into trunk, this
should be in principle possible to accomplish.

There once was a reference on the "Weeks in Review" about an upcoming
blogentry with more info on the new-admin features... which never
materialized :) Also the wiki on new-admin
http://code.djangoproject.com/wiki/NewAdminChanges isn't giving any
hint on how to accomplish date_hierarchy in external views....

So: could anyone shed some light on this, and point me in the right
direction?

much appreciated!
