How do I describe an enumeration column in a Rails 3 migration?

Answer 1

In a Rails 3 Migration you can do the following:

class CreateFoo < ActiveRecord::Migration
  def change
    create_table :foo do |t|
      t.column :foobar, "ENUM('foo', 'bar')"
    end
  end
end

This will create the table with the single column "foobar" and the values.
