ActiveRecord time and datetime

rubyonrails-talk
1

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.
