I wrote a simple model that acts as a tree behaviour.
The model has a myfield_id field that must follow these rules:
- if parent_id is empty (root) myfield_id can't be blank
- if parent_id is not empty myfield_id must be blank (children)
So I wrote a isUnique validation rule for myfield_id. And
As I can't see your full code from the moment you retrieve the
Category and until you try to save it, I can't be sure that you have
provided the Category.id at the time of saving the updated parent_id.
I just imagine that CakePHP actually may try to add a new record, in
which case the isUnique
