Ruby on Rails manual

2.8. Moving Forward

In the next chapter, we'll look at managing relationships between Active Record classes. We'll see most types of Active Record relationships in action, including:

belongs_to
has_one
has_many
has_and_belongs_to_many
acts_as_list
acts_as_tree

We'll build each of these into our evolving Photo Share object model. Then, we'll take a very quick look at two other relationships: inheritance and composition. By the end of the next chapter, we'll have a fully functioning, database-backed object model.
