Cristian,
Can you tell us more about your existing usage of GeoDjango? Do you
have django models that have spatial data columns yet? If not then you
may want to download some of the sample GeoDjango projects from
geodjango-basic-apps. If you do already have models that use geodjango
then rendering with Mapnik may be the next step. Along these lines
I've written code to render django querysets and model instances to
Mapnik but this code is not public ATM. However that's the easy part
and the real challenge to getting beautiful maps is creating
stylesheets for Mapnik which is a topic indepedent of django. For that
issue I'd recommend looking into Cascadenik.

Hi Cristian,
It depends on what you want to do.
It's quite easy to have a Django view returning a map image using
Mapnik
Python bindings. You would simply write the image to the HttpResponse
object.
I need vectorial data.
If you use GeoDjango, you will probably need to draw some of your
model
instances on the Mapnik map. For this purpose, you could create a
PostGIS DataSource object and point it to the relevant tables in your
model backend. I don't know how it would work if your DB backend is
not
Postgres/PostGIS however. This solution is not portable and
unfortunately does not rely on Django QuerySet objects but I don't
know
any better solution.
Yes, i am using postgis, really i always use postgres, i am going to
read something about draw my models instances on the mapnik, i also
find everyblock code[1] it get some code with mapnik and defined as:
"A simple wrapper class around Mapnik's Map that provides a little
friendlier interface to setting up a basic map and for common tasks."
I see the maps what mapnik produce and are so beauty, but i need
more GIS knowledge.
Thanks,
