cakephp 2, edit record in modal by bootstrap - cakephp

Question

How to edit a record with Cakephp and modal bootstrap?
Because when I edit a contact, I get the error 500?
missing view The view for UserContactsController:: admin_modal_edit()
was not found.
In to controller admin_modal_edit() I have set $this->layout = NULL;
These are the files of the app.
File: user/view.ctp with list of contact and the modal for add or edit.
BUTTON FOR EDIT OR DELETE
<?php echo $userContact['UserContactType']['title']; ?>: <?php echo $userContact['contact']; ?>
<?php echo __('Edit'); ?>
BOOTSTRAP MODAL
<?php
echo $this->Form->create('UserContact', array('url' => array('admin' => true, 'prefix' => 'admin', 'plugin' => 'user', 'controller' => 'user_contacts', 'action' => 'modal_edit')));
?>
<?php echo $this->Form->input('UserContact.id', array('class' => 'form-control')); ?>
<?php echo $this->Form->input('UserContact.user_id', array('default' => $user_id, 'type' => 'hidden')); ?>
<?php echo $this->Form->input('UserContact.user_contact_type_id', array('class' => 'form-control', 'empty' => true)); ?>
<?php echo $this->Form->input('UserContact.contact', array('class' => 'form-control')); ?>
<?php echo $this->Form->submit(__('Save'), array('div' => false, 'class' => 'btn btn-success')); ?>
<?php echo $this->Form->end(); ?>
File: controller/UsersController.php that generates view.ctp
public function admin_view($id = null) {
if (!$this->User->exists($id)) {
throw new NotFoundException(__('Invalid user'));
}
$user_id = $id;
$options = array(
'contain' => array('UserContact' => 'UserContactType', 'UserGroup', 'UserState', 'UserGender', 'UserAddress' => 'UserAddressType', 'UserPaymentType', 'Item', 'Comment'),
'conditions' => array('User.' . $this->User->primaryKey => $id));
$this->set('user', $this->User->find('first', $options));
// blocco find list
$userContactTypes = $this->UserContactType->find('list');
$userAddressTypes = $this->UserAddressType->find('list');
$this->set(compact(array('userContactTypes', 'userAddressTypes', 'user_id')));
}
File: controller/UserContactsController.php for the modal
public function admin_modal_edit() {
$id = $this->request->query('id');
$this->layout = NULL;
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->UserContact->save($this->request->data)) {
$this->Session->setFlash(__('The record has been saved'), 'flash/success');
$this->redirect(array('controller' => 'users', 'action' => 'view', $this->request->data['UserContact']['user_id']));
} else {
$this->Session->setFlash(__('The record could not be saved. Please, try again.'), 'flash/error');
}
} else {
if (!empty($id)) {
$options = array('conditions' => array("UserContact.{$this->UserContact->primaryKey}" => $id));
$this->request->data = $this->UserContact->find('first', $options);
}
}
}

Answer 1

Your issue is that CakePHP is trying to render the 'admin_modal_edit.ctp' View template.
If you don't want CakePHP to render anything set autoRender to false:-
public function admin_modal_edit() {
$this->autoRender = false;
}
This will prevent CakePHP from looking for a View template to render.
$this->layout = null does not stop Cake from attempting to render templates. Which I suspect is what you're trying to achieve.

Answer 2

This error is showing because cakephp is complaining about the function admin_modal_edit for not having a view since it cannot find the admin_modal_edit.ctp in the view folder of your controller.
To fix this, add this
$this->autoRender = false
to your function admin_modal_edit to disable the rendering of view for that function.
So your function should look like this.
public function admin_modal_edit() {
/** -------------- **/
$this->autoRender = false;
/** -------------- **/
$id = $this->request->query('id');
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->UserContact->save($this->request->data)) {
$this->Session->setFlash(__('The record has been saved'), 'flash/success');
$this->redirect(array('controller' => 'users', 'action' => 'view', $this->request->data['UserContact']['user_id']));
} else {
$this->Session->setFlash(__('The record could not be saved. Please, try again.'), 'flash/error');
}
} else {
if (!empty($id)) {
$options = array('conditions' => array("UserContact.{$this->UserContact->primaryKey}" => $id));
$this->request->data = $this->UserContact->find('first', $options);
}
}
}
