I have models similar to
class Person(Model):
name = CharField(max_length=100)
class Movie(Model):
...
director = ForeignKey(Person)
How would I get the set of all Person objects which are set as the director for any Movie object?
edit: to clarify, if my Movie 'table' consisted of two entries, one with director A and one with director B, and my Person 'table' consisted of the three entries A, B, and C, I would want to get the set {A, B}
