CRUD operation in CakePGP 3

Need Help
1

Hello. I am new in CakePHP 3. Recently I cake bake a table named CmleLanguages. The add, edit, index as well as view cake templates are generated in src. But I do not understand the
codes of CmleLanguages controller. The code segment is below:


class CmleLanguagesController extends AppController
{

    public function index()
    {
        $cmleLanguages = $this->paginate($this->CmleLanguages);

        $this->set(compact('cmleLanguages'));
    }

    public function view($id = null)
    {
        $cmleLanguage = $this->CmleLanguages->get($id, [
            'contain' => []
        ]);

        $this->set('cmleLanguage', $cmleLanguage);
    }

    public function add()
    {
        $cmleLanguage = $this->CmleLanguages->newEntity();
        if ($this->request->is('post')) {
            $cmleLanguage = $this->CmleLanguages->patchEntity($cmleLanguage, $this->request->getData());
            if ($this->CmleLanguages->save($cmleLanguage)) {
                $this->Flash->success(__('The cmle language has been saved.'));

                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('The cmle language could not be saved. Please, try again.'));
        }
        $this->set(compact('cmleLanguage'));
    }

    public function edit($id = null)
    {
        $cmleLanguage = $this->CmleLanguages->get($id, [
            'contain' => []
        ]);
        if ($this->request->is(['patch', 'post', 'put'])) {
            $cmleLanguage = $this->CmleLanguages->patchEntity($cmleLanguage, $this->request->getData());
            if ($this->CmleLanguages->save($cmleLanguage)) {
                $this->Flash->success(__('The cmle language has been saved.'));

                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('The cmle language could not be saved. Please, try again.'));
        }
        $this->set(compact('cmleLanguage'));
    }

    public function delete($id = null)
    {
        $this->request->allowMethod(['post', 'delete']);
        $cmleLanguage = $this->CmleLanguages->get($id);
        if ($this->CmleLanguages->delete($cmleLanguage)) {
            $this->Flash->success(__('The cmle language has been deleted.'));
        } else {
            $this->Flash->error(__('The cmle language could not be deleted. Please, try again.'));
        }

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

Now I am wanting to understand line by line code so that I can realize how these codes are working.

Is there any resource about it?

Thanks.

The functions it uses are all well documented in the cookbook. If there are specifics you want to ask about, that’s much more appropriate than asking for a line by line breakdown.
