eg. in PostsController, one can do this:
$this->viewPath = 'posts/foo';
... to use templates in app/views/posts/foo/ dir. The fact that we
don't need to set $viewPath for every action tells us that it's
already set for us. So, it would be possible to use that to check for
a commonly-named directory inside whichever is at the end of the
current $viewPath.
AppController:
function beforeFilter()
{
parent::beforeFilter();
// other stuff
if (is_dir(APP.'views'.DS.$this->viewPath.DS.'_version2'))
{
$this->viewPath .= DS.'_version2';
}
}
I think this would probably work fine for you although it could become
complicated. For example, I often adjust the $viewPath to point to the
elements/whatever dir and render just an element when sending back an
AJAX response. On the face of it, this shouldn't be too big a problem
when used with the example above, but you should keep in mind that
there may be other reasons for adjusting $viewPath. If your code has
nothing like that going on, you should be fine.
