有更好的方法吗

# Get an instance of the class I am interested in. It has a manytomany relation
instance = Class.objects.get(pk=1)

# Get the highest start date out of all the objects in the manytomany set
max_date = instance.related_set.aggregate(Max("start_date"))

# Return the object with the highest start date in the manytomany set
