I do think that if you don't like something in CakePHP, please write
your own solution to it, then offer it to the CakePHP developers.
I don't see anything wrong with the structure. What you suggest is to
add additional levels to the structure, just so that all records will
look equal inside the structure, starting from Parent through Node to
Child.
What I see that they have done, is eliminated unnecessary levels,
which for me is fine.
The first level holds the record of the model (Parent) you are
querying together with the one level related model (Node). I don't see
that as a problem. Second level holds the records of the model (Node)
together with the one level related model (Child) records. Fine with
me.
Take your own example and just add one more hasMany relationship to
the Parent model - Parent hasMany Ghost. If I would go for your
structure, then it would bring me:
[0]
[Parent]
[0]
[Node]
[0]
[Child]
[1]
[Child]
[1]
[Node]
[0]
[Child]
[1]
[Child]
[2]
[Ghost]
[3]
[Node]
and so on.
Now it is impossible for me to easily use the structure, as I have to
ask every second level related record whether it is a Node or a Ghost.
In CakePHP original structure, I would simply use
$currentRecord[Ghost] and under there would be all the Ghosts :)
Does the above helps you to clarify why the original structure is
good?
Enjoy,
John
