Django: select all A objects that are involved in m2m relationships with any B objects (via B.m2mfield)

Question

I have a following model:

class People(models.Model):
    name=models.CharField

class Recordings(models.Model):
    title=models.CharField
    performers=models.ManyToManyField(People)

I need to get all people who are performers, i. e. people who are in performers list of at least one recording.

SQL would be like this:

SELECT * FROM people WHERE id IN (SELECT DISTINCT people_id FROM recordings_people)

or

SELECT DISTINCT * FROM recordings_people JOIN people ON recordings_people.people_id=people.id

How can I do the same with Django ORM in an elegant way?

Answer 1

As easy as 1,2,3 with exclude:

People.objects.exclude(recordings=None)

Is that elegant enough ? ;)
