Rails migration: t.references with alternative name?

Question

So I have a create_table like this for Courses at a School:

create_table :courses do |t|
  t.string :name
  t.references :course
  t.timestamps
end

Answer 1

As an added answer to this question -- the Model should have the following line to complete the association:

    belongs_to :transferrable_as, class_name: "Course"
    belongs_to :same_as, class_name: "Course"
