Re: Helper or Model Function?

If you have to load a model into your helper (not recommended) you can
use

ClassRegistry::init('ModelName')->find(...);

API: http://api.cakephp.org/class/class-registry#method-ClassRegistryinit

But I agree with John, use requestAction if you need to pull in data
from a view. Here's a thought, is there a way to pass in the needed
flag record to your view? In your controller action, maybe something
like:

$this->set('showLink', $this->Model->find(/*conditions for specific
record*/));

Then in your view you could just:
<? if($showLink):?> LINK <? endif; ?>
