Validation doesn't work (ActiveRecord::BaseWithoutTable)

Hi,

I understand that the active_record_base_without_table is supposed to be
an easy install. So I am not sure why the validation doesn't work out of
the box (base_without_table.rb attached). No valdn error msgs and it
takes all values.
Am I missing any steps?

I am creating a change password page where it compares old_password with
the stored password in the database. And then user can change it.

View simply has :old_password, :new_password, and
:new_password_confirmation

The Password controller:

The validations will be run when you call .save on your instance of Password:

@password.save
