You may well find that you want to automatically know which user is adding or updating your database info. There are a few ways to do this and I recently, inadvertently, let slip that I have a whoDunnit (who did it) behavior which I use for exactly this purpose.

I wasn't sure if I should make it public; trouble is a little knowledge is a dangerous thing, and the technique used here could be (ab)used to bypass some of the structure and features that Cake brings to the developing-a-php-application table.

On a recent project I had to address the requirement that the admin user can "upload any type of file and associate it with any of the models in the system". In reality this seems to be a rather logical and common requirement. For quite a while now I've been collecting bits of info on how to upload files with cake and it's about time to begin sharing the knowledge. Did I say sharing? I meant I'll show you what I know, and hope you show me how to do it better :)
