9364	Spatial queries don't work on inherited geometry fields	jbronn	jbronn	"In the following models `TexasCity` inherits from `City`:

{{{
from django.contrib.gis.db import models

class City(models.Model):
    name = models.CharField(max_length=30)
    point = models.PointField()
    objects = models.GeoManager()

    def __unicode__(self): return self.name

class TexasCity(City):
    tx_county = models.CharField(max_length=30)
    objects = models.GeoManager() # Why does this need to be explicit?

    def __unicode__(self):
        return '%s (%s County)' % (self.name, self.tx_county)
}}}

When performing the following query:
{{{
In [4]: qs = TexasCity.objects.distance(pnt)
}}}

This SQL is generated, which is incorrect (there is no ""point"" column on the `TexasCity` model):
{{{
In [23]: qs.query.as_sql()
Out[23]:
