Sometimes it's too inconvenient and/or inefficient to do all possible
data formatting in model functions (like afterFind). In my opinion,
formatting data with a helper function is often the way to go. It
would be a lot easier if find queries returned data as objects instead
of arrays (then Jerry's $p->getTiming() example could be used on an
'active record' instead of creating a new class instance), but that's
the way the cookie crumbles.
Jerry's solution is really only intensive if (A) model caching is
disabled and (B) a new instance is created with every helper call
(which it is). Something like this might be better (in the helper):
function getTiming() {
if (!$this->_project) {
App::import('Model', 'Project');
$this->_project = new Project();
}
return $this->_project->getTiming();
}
Obviously that's a bit of a pseudo-code example, but it helps cut down
on the new class instances, especially if getTiming() will be called
50 times in a foreach() loop. I have helpers with similar functions
that generate router URL arrays for some of the more complex parts of
my projects, mainly so that the web designers - who aren't really Cake
experts - can link to something easily.
But like you said, Jeremy, it's also a good idea to do data formatting
in the model. Either approach works. It's just personal preference.
