title: When not to use Containable Behavior in CakePhp 2.x
body: <p>After a few times adding Containable Behavior to my various model classes, I have a good mind to simply chuck the line into AppModel instead and thus make every model Containable. Which then makes me wonder, is there any situation where it is not desirable or counterproductive for a particular model to have Containable Behavior?</p>
