How to manage a find in a recursive model with CakePHP?

I have a standard recursive table of categories, each category can have a parent category; how could I perform a find to retrieve the entire categories struct开发者_如何转开发ure?

I tried changing the recursive property but it's limited to 2 levels. Is there a way to do it with purely CakePHP functions/attributes or do I have to write a function and recreate the entire structure by myself?

Cheers,

Nicolas.

why don't you have a look at the tree behavior? It should do you what you're after! Read up at http://book.cakephp.org/view/1339/Tree
