Okay, well this gets weirder.
I've started on the blog tutorial on the website, and I'm working
through is successfully apart from validate isn't appearing in the
model!
Just to check I threw in a var into the model arbitrarily, and tried
to refer to it, but it says that it's not defined. I have to say that
it's looking like my models are being completely ignored and it's just
using AppModel. This is odd.
Model;
class Blog extends AppModel {
var $name = 'Blog';
var $validate = array(
'title' => array(
'rule' => array('minLength', 1)
),
'body' => array(
'rule' => array('minLength', 1)
)
);
var $testingValue = "This is testing";
}
Controller;
class BlogsController extends AppController {
var $name = 'Blogs';
function index() {
print_r($this->Blog->testingValue);
$this->set('blogs', $this->Blog->find('all'));
}
function view($id=null) {
$this->Blog->id = $id;
$this->set('blog', $this->Blog->read());
}
function add() {
if (!empty($this->data)) {
if ($this->Blog->save($this->data)) {
$this->flash('Your blog has been saved.',
'/blogs');
}
}
}
}
Error;
Notice (8): Undefined property: AppModel::$testingValue [APP/
controllers/blogs_controller.php, line 7]
BlogsController::index() - APP/controllers/blogs_controller.php, line

Could this be down to permissions on the server?
