Rails - May 2007 - works on intial show, but not after validation error

I have a shipment model with a method called returnable?

If a shipment has been delivered, it figures out what the last
returnable date is, delivery date + 14 days.

In Shipment Model

def returnable?
    if last_return_date.nil?
      return "Yes"
    else
    n = Time.now.to_i.abs.round
    d = last_return_date.to_i.abs.round
    if d >= n
          return "Yes"
    else
      return nil
    end
  end
end

This works great on the intials edit view, but if the form is submitted
and there is a validation error, it gives the following error message:

NoMethodError in Shipments#update
undefined method `to_i'' for #<Date: 4910233/2,0,2299161>

Just wondering what''s up?

Both the update action and edit action grab the @shipment instance var
the same way, so this should totally work.

If I''m just a noob over complicating the "is this date greater
than this
date" thing and there''s a better way to write that, please feel
free to
correct me.

Any help is appreciated.

Thanks,

Dave

On the writing this less complicated front, I think I''ve got a better 
version:

 def returnable?
    is_one = last_return_date <=> Time.now
    if is_one >= 1
        return "Yes"
    else
        return nil
    end
 end

Seems when my form submits and there''s a validation error, my fields of
type Time get transformed to type Date, so the to_i wasn''t available as
a method.

no clue why that is...

I''m thinking you''ve not got a valid shipment object when you
recover from
the validation error.
Can you post your controller code?

Regards,
Dave

Hi Dave,

I figured this one out. In my database, the date fields were of type 
datetime. However, when I displayed them in the form I was only showing 
mm/dd/yyy via strftime.

So what was a Time object got turned into a Date object if a validation 
error occurred. Since the datetime field only had the date in it anyway, 
I just changed it''s type, changed all my Time.now''s to
Date.today''s and
it''s all fixed.

Thanks for your help,

Dave C
