Cake PHP 2.8.0 not validating - validation

Question

I have the folowing validate inside my Workshops class
public $validate = array(
'programa'=> array(
'allowEmpty' => false,
'required' => true
),
'lugar'=> array(
'allowEmpty' => false,
'required' => true
),
'fecha_inicio'=> array(
'allowEmpty' => false,
'required' => true
),
'fecha_fin'=> array(
'allowEmpty' => false,
'required' => true
),
'objetivo'=> array(
'allowEmpty' => false,
'required' => true
),
'instructor'=> array(
'allowEmpty' => false,
'required' => true
)
);
however when I save with empty fields a record is created in the database, the validation is not being done.
This is the code for my add form
<h1>Agregar Taller</h1>
<?php
echo $this->Form->create('Workshop');
echo $this->Form->input('nombre');
echo $this->Form->input('fecha_inicio',
array(
'label' => 'Fecha Inicio',
'dateFormat' => 'DMYhm',
'minYear' => date('Y') - 0,
'maxYear' => date('Y') + 2,
));
echo $this->Form->input('fecha_fin',
array(
'label' => 'Fecha fin',
'dateFormat' => 'DMYhm',
'minYear' => date('Y') - 0,
'maxYear' => date('Y') + 2,
));
echo $this->Form->input('caracteristica_tec21');
echo $this->Form->input('programa');
echo $this->Form->input('lugar');
echo $this->Form->input('instructor');
echo $this->Form->input('objetivo', array('rows' => '3'));
echo $this->Form->end('Guardar Taller');
?>
And here is my controller
<?php
class WorkshopsController extends AppController {
public $helpers = array('Html', 'Form');
public function index() {
$this->set('workshops',$this->Workshop->find('all'));
}
public function view($id = null){
if(!$id){
throw new NotFoundException(__('Taller inválido'));
}
$workshop = $this->Workshop->findById($id);
if (!$workshop) {
throw new NotFoundException(__('Taller inválido'));
}
$this->set('workshop', $workshop);
}
public function add() {
if ($this->request->is('post')) {
$this->Workshop->create();
if ($this->Workshop->save($this->request->data)) {
$this->Flash->success(__('El taller se ha agregado'));
return $this->redirect(array('action' => 'index'));
}else{
$this->Flash->error(__('No se ha podido agregar el taller'));
}
}
}
}
?>

Answer 1

You suppose to add a message field in every form field's validation, this is the message which shown in view file. Please see the below:
public $validate = array(
'programa' => array(
'allowEmpty' => false,
'required' => true,
'message' => "Please Enter the programa."
),
'lugar' => array(
'allowEmpty' => false,
'required' => true,
'message' => "Please Enter the lugar."
),
'fecha_inicio' => array(
'allowEmpty' => false,
'required' => true,
'message' => "Please Enter the fecha_inicio."
),
'fecha_fin' => array(
'allowEmpty' => false,
'required' => true,
'message' => "Please Enter the fecha_fin."
),
'objetivo' => array(
'allowEmpty' => false,
'required' => true,
'message' => "Please Enter the objetivo."
),
'instructor' => array(
'allowEmpty' => false,
'required' => true,
'message' => "Please Enter the instructor."
)
);
