I'm developing a forum and my db schema is roughly equivalent to the
following:
class Topic(models.Model):
head = models.CharField()
body = models.TextField()
created = models.DateTimeField(auto_now_add=True)
class Post(models.Model):
body = models.TextField()
topic = models.ForeignKey(Topic)
created = models.DateTimeField(auto_now_add=True)
The question is: how to construct a query to fetch 20 latest Topics with 5
latest Posts for each of these Topics ? As I understood, prefetch_related
isn't suitable since it cannot limit the number of related objects.
