Hay, i have a simple rating system for a property. You give it a mark out of 5 (stars). The models are defined like this
def Property(models.Model)
# stuff here
def Rating(models.Model)
property = models.ForeignKey(Property)
stars = models.IntegerField()
What i want to do is get a property, find all the Rating objects, collect them, then get the average 'stars' from them.
any ideas how to do this?
