How does Django's ORM manage to fetch Foreign objects when they are accessed

Question

Been trying to figure this out for a couple of hours now and have gotten nowhere.

class other(models.Model):
    user = models.ForeignKey(User)


others = other.

This will not explain how exactly Django goes about it, but what you are seeing is Lazy Loading in action. Lazy Loading is a well known design pattern to defer the initialization of objects right up until the point they are needed. In your case until either of o = others[0] or type(o.user) is executed. This Wikipedia article may give you some insights into the process.
