UUID as column type in create_join_table

via BigBinary

Rails 5 has started supporting UUID as a column type for primary key, so create_join_table should also support UUID as a column type instead of only integers.

class CreateJoinTableCustomerProduct < ActiveRecord::Migration[5.0]
  def change
    create_join_table(:customers, :products, column_options: {type: :uuid})
  end
end
