Hi amprodes,

I had the same problem. The cookbook states that you should not use postlinks inside another form.
I think removing the Account form will do the trick.

hope this helps,
Els

 
Move the postlink

#### What I did

1.- This is my model:

--------------------------------------------------------------------------------------

<pre>  

 class Account extends AppModel {

public $name = 'Account'; 

public $belongsTo = array(

'Client' => array(

            'className' => 'Client',

            'foreignKey' => 'client_id'

        ),

'Accounttype' => array(

            'className' => 'Accounttype',

            'foreignKey' => 'accounttype_id'

        )

    );

 

public $hasMany = array(

'Event' => array(

            'className' => 'Event',

            'foreignKey' => 'account_id',

'dependent'=> true

        ), 

'Plot' => array(

            'className' => 'Plot',

            'foreignKey' => 'account_id',

'dependent'=> true

        ),

'Widget' => array(

            'className' => 'Widget',

            'foreignKey' => 'account_id',

'dependent'=> true

        )  

);

 

 

}

</pre>

--------------------------------------------------------------------------------------

2.- **This is my controller:**

--------------------------------------------------------------------------------------

<pre>

class AccountsController extends AppController {

    public $helpers = array ('Html','Form');

 

    function index($client_id) {

        $this->set('accounts', $this->Account->find('all', array('recursive' =>1, 'conditions' => 'Account.client_id ='. $client_id)));

$this->set('client_id', $client_id);

    }

public function view($id = null) {

        $this->Account->id = $id;

        $this->set('account', $this->Account->read());

    }

public function add($client_id) { 

        if ($this->request->is('post')) {

            if ($this->Account->save($this->request->data)) {

                $this->Session->setFlash('Your account has been added.'); 

if($this->request->data['Account']['accounttype_id'] == 2){

$this->redirect(array('controller' => 'twitteraccounts', 'action' => 'connect'));

}

            }

        }

 $accounts = $this->Account->find('list'); 

 $accounttype  =  $this->Account->Accounttype->find('list', array('fields'  => array('Accounttype.id', 'Accounttype.description')));

 $this->set('client_id', $client_id);

      $this->set('accounts', $accounts);

    }

function edit($id = null, $client_id) {

    $this->Account->id = $id;

$this->set('id', $id);

    if ($this->request->is('get')) {

        $this->request->data = $this->Account->read();

    } else {

        if ($this->Account->save($this->request->data)) {

            $this->Session->setFlash('Your account has been updated.');

            $this->redirect(array('action' => 'index', $client_id));

        }

    }

 $accounts = $this->Account->find('list'); 

 $accounttype  =  $this->Account->Accounttype->find('list', array('fields'  => array('Accounttype.id', 'Accounttype.description')));

      $this->set('accounts', $accounts);

 $this->set('accounttype', $accounttype);

  $this->set('client_id', $client_id);

}

public function delete($id, $client_id) {

 

    $id = $this->request->params['pass'][0];

   

    //the request must be a post request

    //that's why we use postLink method on our view for deleting user

   if( $this->request->is('get') ){

   

        $this->Session->setFlash('Delete method is not allowed.');

        $this->redirect(array('action' => 'index',$client_id));

       

        //since we are using php5, we can also throw an exception like:

        //throw new MethodNotAllowedException();

    }else{

   

        if( !$id ) {

            $this->Session->setFlash('Invalid id for Account');

            $this->redirect(array('action'=>'index',$client_id));

           

        }else{

            //delete user

            if( $this->Account->delete($id, $cascade = true) ){

                //set to screen

                $this->Session->setFlash('Account was deleted.');

                //redirect to users's list

                $this->redirect(array('action'=>'index',$client_id));

               

            }else{ 

                //if unable to delete

                $this->Session->setFlash('Unable to delete Account.');

                $this->redirect(array('action' => 'index'));

            }

        }

    }

}

}

</pre>

--------------------------------------------------------------------------------------

3.- **This is the view:**

--------------------------------------------------------------------------------------

       echo $this->Html->addCrumb('Clients', '/clients'); 

       echo $this->Html->addCrumb('Accounts', '/accounts'); 

       echo $this->Form->create('Account'); 

            foreach($accounts as $account): ?>

   <table cellspacing=0 cellpadding=0 style="width:600px">

<tr>

<td>

  <?php echo $account['Accounttype']['description'] ?></br> 

                 </td> 

<td>

                  <?php echo $this->Html->link('Edit', array('action' => 'edit', $account['Account']['id'], $client_id)); ?>

                 </td> 

<td>

                 <?php // echo $this->Html->link('Del', array('action' => 'delete', $account['Account']['id'], $client_id)); ?>

                </td> 

<td>

                <?php echo $this->Html->link('Add Event', '/events/add/'.$account['Account']['id'], array('action' => 'add', $account['Account']['id'])); ?></td>  

<td><?php echo $this->Form->postLink('Delete',array('action' => 'delete', $account['Account']['id'], $client_id),null,  'Are you sure?');?></td>

        </tr>  

</table>

<?php 

endforeach; echo $this->Form->end();

?>

<div style="float:right"><?php  echo $this->Html->link('Back', array('controller' => 'clients', 'action' => 'index')); ?></div>

--------------------------------------------------------------------------------------

What happened

Everything works great but delete button won't delete the last row remaining in accounts list i meant delete works but not in the last row remaining and i think the problem is when the delete postLink() get render, it formed well in all rows but not in the first one the "(form blablabla) (/form)" its not created in the first row and i just get (input blablabla) without form tag so when i click "delete" nothing happens! just get # at the end of the url

What I expected to happen

i expect to get a beautiful blank list saying "there are not accounts assigned to this client" when i delete the last row!

pd: thanks for help me out! and sorry for my bad english!
