Re: Validate from within a model

You dont need to use validates(), just set an error manually.

$this->invalidate('fields', 'Error message.');

Also, your approach is still wrong IMO. You should be doing all error
checking before any save functionality is triggered. In what scenario
will the image NOT copy/transfer? I have yet to ever run into that
problem.
