CakePHP wie man einen neuen Datensatz in der Indexansicht hinzufügt

Question

Ich bin neu bei cakePHP und frage mich, wie ich ein Formular in der Indexansicht hinzufügen kann, um der Datenbank einen neuen Datensatz hinzuzufügen. Ich meine, in der Index.ctp kann die Liste der Datensätze angezeigt werden und darunter befinden sich einige Platzhalter mit einer Hinzufügen-Schaltfläche zum Einfügen in die DTB. Muss ich den Controller ändern?

Ich habe versucht, ein Formular in der Indexansicht hinzuzufügen, mit dem Ziel ist ../add, aber nach dem Klick reichen Sie immer umleiten auf die ../add/{number} und ich muss die Informationen erneut einreichen. Hier wird der Code im zu ändern versuchen:

<div class="departments index large-9 medium-8 columns content"> 
<h3><?= __('Departments') ?></h3> 
<table cellpadding="0" cellspacing="0"> 
    <thead> 
     <tr> 
      <th scope="col"><?= $this->Paginator->sort('id') ?></th> 
      <th scope="col"><?= $this->Paginator->sort('name') ?></th> 
      <th scope="col"><?= $this->Paginator->sort('modified') ?></th> 
      <th scope="col" class="actions"><?= __('Actions') ?></th> 
     </tr> 
    </thead> 
    <tbody> 
     <?php foreach ($departments as $department): ?> 
     <tr> 
      <td><?= $this->Number->format($department->id) ?></td> 
      <td><?= h($department->name) ?></td> 
      <td><?= h($department->modified) ?></td> 
      <td class="actions"> 
       <?= $this->Html->link(__('View'), ['action' => 'view', $department->id]) ?> 
       <?= $this->Html->link(__('Edit'), ['action' => 'edit', $department->id]) ?> 
       <?= $this->Form->postLink(__('Delete'), ['action' => 'delete', $department->id], ['confirm' => __('Are you sure you want to delete # {0}?', $department->id)]) ?> 
      </td> 
     </tr> 
     <?php endforeach; ?> 
    </tbody> 
</table> 
<div class="paginator"> 
    <ul class="pagination"> 
     <?= $this->Paginator->first('<< ' . __('first')) ?> 
     <?= $this->Paginator->prev('< ' . __('previous')) ?> 
     <?= $this->Paginator->numbers() ?> 
     <?= $this->Paginator->next(__('next') . ' >') ?> 
     <?= $this->Paginator->last(__('last') . ' >>') ?> 
    </ul> 
    <p><?= $this->Paginator->counter(['format' => __('Page {{page}} of {{pages}}, showing {{current}} record(s) out of {{count}} total')]) ?></p> 
</div> 
<div class="departments form large-9 medium-8 columns content"> 
<!-- $this->Form->create("Post",array('action'=>'add')); --> 
    <?= $this->Form->create($department,['url' => ['action' => 'add']]) ?> 
    <fieldset> 
     <legend><?= __('Add Department') ?></legend> 
     <?php 
      echo $this->Form->control('name'); 
      echo $this->Form->control('description'); 
      echo $this->Form->control('subjects._ids', ['options' => $subjects]); 
     ?> 
    </fieldset> 
    <?= $this->Form->button(__('Submit')) ?> 
    <?= $this->Form->end() ?> 
</div> 

auf dem Controller:

public function index() 
{ 
    $departments = $this->paginate($this->Departments); 

    // $this->add(); 
    $subjects = $this->Departments->Subjects->find('list', ['limit' => 200]); 
    $this->set(compact('departments', 'subjects')); 
    $this->set('_serialize', ['departments']); 


} 

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

      return $this->redirect(['action' => 'index']); 
     } 
     $this->Flash->error(__('The department could not be saved. Please, try again.')); 
    } 
    $subjects = $this->Departments->Subjects->find('list', ['limit' => 200]); 
    $this->set(compact('department', 'subjects')); 
    $this->set('_serialize', ['department']); 
} 

Answer 1

Es sieht gut aus, müssen Sie $department in Index-Methode setzen sowie Ihre Form ist in Indexseite und das Formular verwendet $department Variable.Machen Sie Ihre Index-Methode in etwa wie folgt:

public function index() 
{ 
    $departments = $this->paginate($this->Departments); 
    $department = $this->Departments->newEntity(); // added 
    // $this->add(); 
    $subjects = $this->Departments->Subjects->find('list', ['limit' => 200]); 
    $this->set(compact('departments', 'subjects,'department')); // edited 
    $this->set('_serialize', ['departments']); 


} 

Answer 2

Nun, ich fand die Antwort selbst, es funktioniert, aber ich weiß nicht, ob es der richtige Weg ist diese Situation.

Ich halte alle Steuerungen gleich wie oben, nur das Formular in index.ctp ändern

<?= $this->Form->create(null,['url' => ['action' => 'add']]) ?> 
    <fieldset> 
     <legend><?= __('Add Department') ?></legend> 
     <?php 
      echo $this->Form->control('name'); 
      echo $this->Form->control('description'); 
      echo $this->Form->control('subjects._ids', ['options' => $subjects]); 
     ?> 
    </fieldset> 
    <?= $this->Form->button(__('Submit')) ?> 
    <?= $this->Form->end() ?>
