Rails - Dec 2011 - ActiveRecord time and datetime

Hi,

Suppose I have a model class which has a time field:

class CreateAppointments < ActiveRecord::Migration
  def change
    create_table :appointments do |t|
      t.string :name
      t.datetime :startTime
      t.datetime :endTime
      t.string :description

      t.timestamps
    end
  end
end

When I test drive it in rails console, I can input any value int he
startTime and endTime such as:

a = Appointment.new()
a.startTime = 1234
a.endTime = 5678
a.save()

My question is does Rails support some basic data type validation for us
so that we can always input a correct format?

Thanks,
Kahou

The way to do it is to always go via a Time object.  If the user is
entering data then parse that into a Time object then save that.  If
you need to check that the time is in a particular range for example
then also include a validation in the model.
