I am trying to transform geometry column type in django, here is my model
class Network(models.Model):
name = models.CharField(max_length=50, blank=True)
alias = models.CharField(max_length=100, blank=True)
geometry = models.GeometryField(srid=3857, null=True, blank=True)
bbox = models.GeometryField(srid=3857, null=True, blank=True)
objects = models.GeoManager()
class Meta:
db_table = u'tbl_network'
def __unicode__(self):
return '%s' % self.name
Problem is that when i tried to transform bbox it does not transform it
Network(srid=3857).values('geometry','bbox')
SELECT ST_Transform("tbl_network"."geometry", 3857), "tbl_network"."bbox"
FROM "tbl_network"
Above query automaticly tranform geomtery field and igonre bbox field
So i tried it different different way
Network(srid=3857).values('bbox')
SELECT "tbl_network"."bbox" FROM "tbl_network"
Now this query totally ignored transform function.
So my questions is,
How can i transform specific column of model?
thank you
