Question

I have a custom validation method that ensures an alarm can only be set in the future..

class Alarm < ActiveRecord::Base

  validate :alarm_set_in_the_future

  def alarm_set_in_the_future
    if time <= DateTime.current
      errors.add(:alarm, "Please Choose A Future Date & Time")
    end
  end

This works great and the tests pass upon creating a new Alarm record. Awesome…

However, when editing an Alarm, the time variable gets set to the following datetime and I have no idea why!

2000-01-01 03:28:00 UTC

Consequently, the validation fails.

Where is that time parameter getting reset? Help!

Answer 1

Take a look at what’s being submitted from your form. It seems unlikely that the problem lies in the validation itself.

Most likely, you’re getting some bogus data from the form when saving the record. What is the value of @alarm.time in the controller before you save? What does the params hash look like?
