Re: CakePHP 3: 2 Qs - Response From Filter & Helper Constructor

You are setting this message:

$response->body(json_encode([ 'errors' => [ 'Invalid request to api' ] ]));

But getting this error:

{"errors":["Invalid request to inventory_api"]}

That makes me think that you are setting the response from somewhere else, and not where you think.

In your custom helper you would do:

 public function __construct(\MyNS\View\AppView $view, $config=[]) {

And that should fix it!

Hi all,

I'm porting a fairly sizable CakePHP 1.3 app to CakePHP 3 and have run into a couple of issues with which hopefully someone can help me out.

Rejecting a Request from a Filter

First, I'm trying to reject a request from a filter. I am setting the response's type to json and its status code to 403, but the app is still reporting 200. The code is:

$response = $event->data['response'];            
$response->type('application/json');
$response->body(json_encode([ 'errors' => [ 'Invalid request to api' ] ]));
$response->statusCode(403);

$event->stopPropagation();
           
return $response;

Request, response, and status are:

Status 200 OK

I'm guessing I'm somehow doing this wrong?

Constructing a Helper

Second, I have several helpers but they are failing to be constructed due to type issues. While I have been using PHP off and on for nearly 15 years (since version 3),  I am new to the namespacing found in the newest versions, so it may be related. Below is one example. I am adding to the helpers collection thusly in the AppController:

$this->helpers[] = 'NavBar';

The class constructor is defined as:

namespace MyNS\View\Helper;

use Cake\View\Helper;
use Cake\Core\Configure;

class MyHelper extends Helper {
   
    public function __construct(\MyNS\View $view, $config=[]) {

The warning I am receiving is:

Argument 1 passed to MyNS\View\Helper\MyHelper::__construct() must be an instance of MyNS\View, instance of MyNS\View\AppView given

Thanks for any help you may be able to provide to either question!

Chris
