Rails offers two different ways to declare a many-to-many relationship between models. This makes the association indirectly, through a join model: With polymorphic associations, a model can belong to more than one other model, on a single association. For example, you might have a picture model that belongs to either an employee model or a product model.

Here's how this could be declared: From an instance of the Employee model, you can retrieve a collection of pictures: Similarly, you can retrieve product. If you have an instance of the Picture model, you can get to its parent via picture. To make this work, you need to declare both a foreign key column and a type column in the model that declares the polymorphic interface: For example, you may want to store all employees in a single database model, but be able to trace relationships such as between manager and subordinates.
