Properly setting up CacheHelper
Hi! I have a strange issue with CacheHelper and perhaps it's because I do
some error in configuration.
For the first time I encountered this problem while working on my main
project.
After it, I have downloaded CakePHP 2.2.4 and created an app for testing.
As mentioned above I'm trying to use CacheHelper.
What I did:
New CakePHP 2.2.4, freshly downloaded. No changes was made except of:
*core.php:*
I added Configure::write('Cache.check', true); as mentioned in the Cookbook
*bootstrap.php:* (It was already there, so I did not make any changes.)
Configure::write('Dispatcher.filters', array(
'AssetDispatcher',
'CacheDispatcher'
));
*Controller/NewsController.php* – this is my controller for testing.
?php
class NewsController extends AppController {
public $helpers = array('Cache');
public $cacheAction = array(
'view' = 36000,
'index' = 48000
);
public function index() {
}
public function clear() {
clearCache();
}
}
*View/News/index.ctp*:
Things went OK!
What happened
On the first page load (domain.com/news) I can see my view rendered as
expected.
If I try to access page for the second time I get the error:
Error: Class 'AppController' not found
File: ../app/Controller/NewsController.php
Line: 2
And as long as I did not clear the cache, I get the same error.
After clearing cache I can once again load page and after that everything
is repeated and I get the same error.
Thanks in advance.

Re: Properly setting up CacheHelper
thats because you forgot a vital part above your
class NewsController extends AppController {}
above it add `App::uses('AppController', 'Controller');`
It is important that you always specify all used classes in your files at
the top.

Re: Properly setting up CacheHelper
Thank you, Mark.
It solves the problem, but I was absolutely sure that it is enough to
specify `App::uses('AppController', 'Controller');` in the
/Controller/AppController.php
I think they should definitely add the importance of inclusion of this
fragment of code in the Cookbook.

Re: Properly setting up CacheHelper
as I stated above, it is vital that you always include all uses classes
throughout your files.
so, no. it is not enough - as you just experienced yourself. it might work
up to some point - and than it breaks.
the App::uses can be compared to require statements. If you don't tell cake
what files are required it fill fail eventually.
same goes for helpers, models, behaviors, ...
