Confused. I have some code in a migration that only works when I run rake db:rollback db:migrate but not if I run rake db:rollback then rake db:migrate.

Migration:

# ...add_latitude_and_longitude_to_organisation.rb
class AddLatitudeAndLongitudeToOrganisation < ActiveRecord::Migration
  def up
    add_column :organisations, :latitude, :float
    add_column :organisations, :longitude, :float
