how to debug on a "add" function of controller

hello,

i've inserted a debug($this->request->data) into the add function of my controller but nothing is rendered when i've add some data

code looks like:

    public function add()

    {

        $magazine = $this->Magazines->newEntity();

        if ($this->request->is('post')) {

            debug($this->request->data);

            $magazine = $this->Magazines->patchEntity($magazine, $this->request->data);

            if ($this->Magazines->save($magazine)) {

                $this->Flash->success(__('The magazine has been saved.'));

                return $this->redirect(['action' => 'index']);

            } else {

                $this->Flash->error(__('The magazine could not be saved. Please, try again.'));

            }

        }

        $periodicity = $this->Magazines->Periodicity->find('list', ['limit' => 200]);

        $categories = $this->Magazines->Categories->find('list', ['limit' => 200]);

        $this->set(compact('magazine', 'periodicity', 'categories'));

        $this->set('_serialize', ['magazine']);

    }

what i'm doing wrong?

thanks in advance
