What is the proper way to select all fields plus a few additional
calculated fields? Here is my basic query with no calculated field
location = db(db.location.id == loc_id).select().first()
This query returns location as a <class 'gluon.dal.Row'> object with fields
for the location table as attributes. With this I can access
location.address for example.
Now to add calculated fields to get the geo spatial coordinates from the
point field, I'm trying this:
location = db(db.location.id == loc_id).select(db.location.ALL,
db.location.point.st_x().
with_alias('latitude'),
db.location.point.st_y().
with_alias('longitude')).first()
Is this the proper way? This returns a <class 'gluon.dal.Row'> object with
a "location" field (which is in turn also a Row object) and "latitude" and
"longitude" fields.
Now in order to access the address field I must do location.location.address
How can make it so I can access the fields like location.address and
location.latitude?
