Hi,
if you have a std:
class Director(Base):
name = ...
movies = relationship(Movie...)
you can do something as::
session.query(Director).filter_by(movies=None)
that is nicely translated into::
SELECT director.id AS director_id, director.last_name AS
director_last_name, director.first_name AS director_first_name,
director.nation AS director_nation
FROM director
WHERE NOT (EXISTS (SELECT 1
FROM movie
WHERE director.id = movie.director_id))
How can I nagate it, i.e. If I want all records that *do* have movies?
TIA
