         function index()
         {
            $this->set('posts', $this->Post->find('all'));
         }

            $this->Post->id = $id;
            $this->set('post', $this->Post->read());
         }
         function admin()
         {
            $this->set('posts', $this->Post->find('all'));
         }
         function add()
         {
            if (!empty($this->data))
            {
               if ($this->Post->save($this->data))
               {
                  $this->Session->setFlash('Your post has been saved.');
                  $this->redirect(array('action' => 'admin'));
               }
            }
         }
         function edit($id = null)
         {
            $this->Post->id = $id;
            if (empty($this->data))
            {
               $this->data = $this->Post->read();
            }
            else
            {
               if ($this->Post->save($this->data))
               {
                  $this->Session->setFlash('Your post has been updated.');
                  $this->redirect(array('action' => 'admin'));
               }
