title: How can I tell if I'm in beforeSave from an edit or a create? CakePHP
body: <p>I have a model where I need to do some processing before saving (or in certain cases with an edit) but not usually when simply editing.  In fact, if I do the processing on most edits, the resulting field will be wrong.  Right now, I am working in the beforeSave callback of the model.  How can I tell if I came from the edit or add?</p>
