Hello all,
I am a seasoned developer and have been building apps with Cake for
some time. Today I came up against a bug that I cannot figure out -
Cake just STOPPED working. I'm using the 1.2 beta on php 5.x and all
has been well throughout this dev. However, I moved a block of code
into the AppController file to make it available to everything and it
was a bit buggy. So, I moved it back to where it came from... that's
all. Now I am getting a fatal error:
Call to a member function findByUri() on a non-object in C:\Program
Files\Zend\Apache2\htdocs\app\app_controller.php on line 52
In spite of this:
var $uses = array('Page', 'User', 'PageModule', 'News', 'Location',
'Content', 'UserLocation');
...and in spite of the fact it was working fine before! As I said, I
know what I'm doing and I cannot understand why Cake isn't creating an
instance of the "Page" model - or any classes for that matter: the
problem exists for components as well. Here is the (abridged)
beforeRender() method I'm using for this:
function beforeRender()
{
// see if there's any $bodytext set to pass into the page
along
with the dynamic title
$q = $this->Page->findByUri(str_replace('/', '', $this-
>params['url']['url'])); // line 52
if (!empty($q)) {
$q = $this->Content->findById($q['Page']['content_id']);
$this->set('pagetitle', $q['Content']['title']);
$this->set('bodytext', $q['Content']['body']);
}
}
I am desperate to get to the bottom of this... has anyone experienced
this before? I really need a hand here! I have (somewhat desperately!)
reinstalled Cake's Core, restarted my machine (in the hope that PHP
itself was the culprit!) and looked everywhere for the cause of the
bug. No joy. The full AppController file is pasted at the bottom of
this message.
Looking forward to your responses,
Matt
