It's expressing a many-to-many or many-to-one relationship. For example, if you were to take the poll app from the Django tutorial and translate it into Rails, you'd have something like this in your Poll model: Class Poll < ActiveRecord::Base has_many :choices And then your Choice model would look like: Class Choice < ActiveRecord::Base belongs_to :poll And this would accomplish the same as the ForeignKey field in the Choice model in Django. Nothing in Python really prevents this sort of system, but in Python it's generally preferred to be more explicit about things, which is why in Django you specify all your model's fields in the class, instead of having them inferred from the database as in Rails. -- "May the forces of evil become confused on the way to your house." -- George Carlin
