Action not defined in controller cakephp - url

Question

I am having this issue while using findbyid to get a unique url for a page on my shared hosting. The problem I have is that I keep getting the following error while trying to access the unique page via the Id number of the item on shared hosting(i dont get this issue on localhost):
Error: The action item is not defined in controller ProductsController
Error: Create ProductsController::item() in file: app/Controller/ProductsController.php.
However item is defined in the productscontroller:
public function item($id = null) {
if (!$id) {
throw new NotFoundException(__('product not found'));
}
$items = $this->Product->findById($id);
if (!$items) {
throw new NotFoundException(__('Invalid post'));
}
$this->set('item', $items);
}
you can see the problem at this url: http://entourmag.com/hava/products/item/39
it works on localhost via wamp so I am not sure what the problem is.
Thanks in advance

Answer 1

Well I figured out the issue. The problem was with the files uploaded; the files uploaded were incomplete or missing, when I check the ProductsController.php file I realised that most of the code was missing. Reuploading solved the problem.
For others with problematic internet connection take note of this while coding.

Error: A Database connection using "Mysql" was missing or unable to connect.
The database server returned this error: SQLSTATE[HY000] [1045] Access denied for user 'root'#'localhost' (using password: NO)
Notice: If you want to customize this error message, create app/View/Errors/missing_connection.ctp
I think you have not created/configured your database.php in app/Config

Answer 3

I am using cakephp 3.8 and I figure out one possible cause of this kind of messages.
In my case, I am expecting the __construct method is responsible for creating the base class.
And the solution is to use initialize method, like so:
function initialize() {
parent::initialize();
}
In conclusion, we should more carefully read the documentation, it clearly stated here and please take time to do the 20 min cms tutorial
