Question

Good morning guys.
In error_log CakePHP is accusing the following:

28/11/2011 10:13:27 Error: [MissingControllerException] ImagesController Controller class could not be found.
# 0 /........./app/webroot/index.php (96): Dispatcher-> dispatch (Object (CakeRequest), Object (CakeResponse))
# 1 {main}

I haven’t idea what it is, because I haven’t ImagesController but have ImagesComponent.

Code snippet:

// app/Controller/BrandsController.php    
class BrandsController extends AppController {
public $components = array('Image');
...

public function add() {
    if ($this->request->is('post')) {
        if (!empty($this->request->data)) {

            if(!$this->request->data['Image']['name1']['error']) {
                $this->Brand->create();

                $image_path = $this->Image->uploadImage(
                    $this->request->data['Image'], 
                    'Brands',
                    array(
                        'folder'=>'upload/imagens/marcas',
                        'resize'=>175,
                        'thumb'=>0,
                        'original'=>false,
                        'name'=>$this->request->data['Brand']['brand']
                    )
                ); 

// app/Controller/Component/ImageComponent.php
class ImageComponent extends Component {

public $components = array('String');

function uploadImage($images, $controller, $data) {
    $erroimg = false;
    $isfile = false;
    ...

What is the cause of this error?
Sorry for my english

Answer 1

Your error log shows a stack trace with the methods leading to the error. In your case Dispatcher::dispatch was called. The docs of this method read:

Dispatches and invokes given Request, handing over control to the involved controller. If the controller is set to autoRender, via Controller::$autoRender, then Dispatcher will render the view. Actions in CakePHP can be any public method on a controller, that is not declared in Controller. If you want controller methods to be public and inaccessible by URL, then prefix them with a _. For example public function_loadPosts() { }` would not be accessible via URL. Private and protected methods are also not accessible via URL.

If no controller of given name can be found, invoke() will throw an exception.
If the controller is found, and the action is not found an exception will be thrown.

Internally, dispatch will call Dispatcher::parseParams to parse the Request to determine the controller to call. If any routes have been configured, parseParams will apply them

Applies Routing and additionalParameters to the request to be dispatched.
If Routes have not been loaded they will be loaded, and app/Config/routes.php will be run.

In other words: you requested a URL that the Dispatcher wants to pass on to the Image controller. You don’t have an ImageController and that’s why you get the error. So, add an ImageController or change how CakePHP routes.
