CakePHP DB field update fail - php

Question

I am using cakePHP why won't the name insert into the table, a null value seams to be passed as the table is updated but with out the name?
Table in Database
CREATE TABLE tests (
id serial not null unique primary key,
name varchar,
created timestamp default CURRENT_TIMESTAMP
)
add.ctp
<?php
echo $this->Form->create('Post');
echo $this->Form->input('name');
echo $this->Form->end('RSVP');
?>
Test Model
<?php
class Test extends AppModel {
var $name = 'Test';
}
TestContoller
<?php
class TestController extends AppController {
public $helpers = array('Html', 'Form');
var $name = "Test";
public function index() {
$this->set('tests', $this->Test->find('all'));
}
public function view($id = null) {
$this->Test->id = $id;
$this->set('Test', $this->Test->read());
}
public function add() {
if ($this->request->is('post')) {
if ($this->Test->save($this->request->data)) {
$this->Session->setFlash('Your post has been saved.');
$this->redirect(array('action' => 'index'));
}
else {
$this->Session->setFlash('Unable to add your post.');
}
}
}
public function edit($id = null) {
$this->Test->id = $id;
if ($this->request->is('get')) {
$this->request->data = $this->Post->read();
}
else {
if ($this->Test->save($this->request->data)) {
$this->Session->setFlash('Your post has been updated.');
$this->redirect(array('action' => 'index'));
}
else {
$this->Session->setFlash('Unable to update your post.');
}
}
}
public function delete($id) {
if ($this->request->is('get')) {
throw new MethodNotAllowedException();
}
if ($this->Test->delete($id)) {
$this->Session->setFlash('The post with id: ' . $id . ' has been deleted.');
$this->redirect(array('action' => 'index'));
}
}
}

In your method you missed to include $this->Test->create();, which will add new row to table and inset new data to it.
public function add() {
if ($this->request->is('post')) {
$this->Test->create(); // missed this line
if ($this->Test->save($this->request->data)) {
$this->Session->setFlash('Your post has been saved.');
$this->redirect(array('action' => 'index'));
}
else {
$this->Session->setFlash('Unable to add your post.');
}
}
}
