Didn't realize you could make a second query in a Virtual field but makes
sense now that I see it. Although I'd rather not make the extra query (2
actually since longitude would need to do the same thing) so I guess I will
just add latitude and longitude directly to my original select instead o
st_*() are db engine functions, you should query the db to get the output
you are looking for. Given that, in your virtual field you should make a
new query, something like that:
Field.Virtual('latitude', lambda row: db(db.location.id == row.location.id).
select(db.location.point.st_x()).first()
i bet that by the time your lambda is running the point has been converted
to a string already. can you see if that is true? i'm not sure how to
invoke db functions in a lambda of a virtual field. :(
