I have a class with an acts\_as\_tree association and I’d like to add  
some additional functionality to take place whenever I try to append  
something to an instances child list. So when I try something like  
my\_object.children \<\< another\_object I’d like to call a method or  
override whatever method I need to do so. Thanks, I welcome any  
advice. -Mike

You can override the method and do whatever you want in your model 🙂
