Yes! Good improvement. And we should do the same thing for one-to-many
fields (ForeignKeys):
"""
class Author(models.Model):
name = models.CharField(...)
class Book(models.Model):
author = models.ForeignKey(Author)
john = Author.objects.get(name='john')
books = list(john.book_set.all())
# Does a database query, but should be smart enough to simply return john.
books[0].author
"""
I'm pretty sure there's a long-standing ticket for this, but I'm not
sure which one it is. Shai, does your solution approach this in a way
that can solve the issue for ForeignKeys as well?
