Hi there,
This is my GeoDjango model:
{{{
from django.contrib.gis.db import models
from django.db.models import fields
class Spot(models.Model):
idSpot = fields.AutoField(primary_key = True)
code = models.CharField(max_length = 30)
poly = models.PointField(spatial_index = True,
srid = 4326,
geography = True)
objects = models.GeoManager()
}}}
When I do this:
{{{
python manage.py shell
from location.models import Spot
from django.contrib.gis.geos import Point
spot = Spot("park",Point(10,10))
spot.save()
}}}
What I get is:
{{{

}}}
Instead if I do:
{{{
spot = Spot(1,"park",Point(10,10))
spot.save()
}}}
Everything goes right if primary key 1 does not already exist. If I check
table in the database, record is there. Also there is a sequence
associated to the primary key.
{{{
location=# \d location_spot
Tabla «public.location_spot»
Columna | Tipo |
Modificadores
---------+-----------------------+----------------------------------------------------------------------------
idSpot | integer | not null valor por omisión
nextval('"location_spot_idSpot_seq"'::regclass)
code | character varying(30) | not null
poly | geography(Point,4326) | not null
Índices:
"location_spot_pkey" PRIMARY KEY, btree ("idSpot")
"location_spot_poly_id" gist (poly)
}}}
Using autofield in Django doesn't work this way, so I think it might be a
bug. I'm using:
- Django 1.2.1 final
- Latest GEOS version
- Latest Proj version
- PostGIS 1.5 latest version
- Ubuntu Linux 9.10
Followed these instructions for installation

from-source]
Thanks, regards
