Rails &Postgres:Мигрирането към change_colomn дава грешка, не може да бъде прехвърлено към тип timestamp без часова зона

В Rails това би изглеждало нещо като

class ChangeStatusUpdatedAtToDateTime < ActiveRecord::Migration
  def up
    remove_column :bookings, :status_updated_at
    add_column :bookings, :status_updated_at, :datetime
  end

  def down
    remove_column :bookings, :status_updated_at
    add_column :bookings, :status_updated_at, :time
  end
end

Ако сте имали данни, които искате да прехвърлите, можете да използвате следния код (не е тестван!):

class ChangeStatusUpdatedAtToDateTime < ActiveRecord::Migration
  def up
    add_column :bookings, :temp_status_updated_at, :datetime
    Booking.update_all("temp_status_updated_at = updated_at")
    remove_column :bookings, :status_updated_at
    rename_column :bookings, :temp_status_updated_at, :status_updated_at
  end

  def down
    add_column :bookings, :temp_status_updated_at, :time
    Booking.update_all("temp_status_updated_at = updated_at")
    remove_column :bookings, :status_updated_at
    rename_column :bookings, :temp_status_updated_at, :status_updated_at
  end
end
