    That restapi is as easy to configure as promised.

The address /xml/mymodel  now presents an xml list  that looks like:

<;object pk="3710" model=&quot;myapp.mymodel"&gt;
<field type=";CharField&quot; name=";custom_id&quot;>XX-83-297</field>


<field type=";DateTimeField" name=";datetime&quot;>2007-07-27 14:59:18&lt;/field>;
<field type=";NoField&quot; name=";point";>POINT (
31.0089240000000004 -82.7168659999999960)</field&gt;
<field type=";IntegerField" name=";velocidad&quot;>71</field&gt;
<field to="myotherapp.section"; name=";section&quot; rel="ManyToOneRel">1</field>

<field to="auth.user&quot; name=";responsable" rel="ManyToOneRel">3</field>
</object> 

That NoField type, is it ok?

Well, it depends what you're going to do with it.  

That 'NoField' comes from
django.db.models.fields.Field.get_internal_type.  It was
originally
used during table creation (as in manage.py syncdb) and
introspection.
 It is also included when serializing objects (as the REST
interface
does), but it appears to be only serving as an annotation
for
convenience-- it's not actually used in deserialization.

The problem you may run into is that there are various types
of GIS
fields, all of which will return NoField.  Further, other
custom field
types may return NoField and not actually be GIS fields. 
Again, this
doesn't affect Django-proper, but if you need to do
something
intelligent based on the type attribute, you may have
trouble.

...A simple solution to fix Django on this issue isn't
immediately
apparent.  I know Malcolm was noodling on improving Field
subclassing,
and this get_internal_type bit is one thing that needs
improvement.

I can tell you that the text value inside the <field
type="NoField".../> for GIS fields is WKT:
http://e
n.wikipedia.org/wiki/Well-known_text
There are libraries for pasting it...
