Re: Cakephp not able to save associated model

Hi Gaurav Kumar

In your add method in the controller:
1. remove the fields option for the retrieval of policies. CakePHP automatically takes id and name when using find(list).

In your add view, the form input for policies will assume that policies belongs in CloudApp.
1. Change to ... input('Policy.id', array('options' => $policies, 'multiple' => true)) ...
The above will tell CakePHP that the values in $policies is to be used for populating the dropdown list for policies.
See also the CakePHP documentation at:
http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html#options-for-select-checkbox-and-radio-inputs

Kindly tell us of the result you get.
Enjoy, John

I've a model `CloudApp` which has HABTM relationship with `Policy` model e.g:

    class CloudApp extends AppModel {

        public $displayField = 'name';        

        public $hasAndBelongsToMany = array(

            'Policy' => array(

                'className' => 'Policy',

                'joinTable' => 'cloudapp_policies',

                'foreignKey' => 'cloud_app_id',

                'associationForeignKey' => 'policy_id',

                'unique' => 'keepExisting',

            )

        );

    

    }

`Policy` model looks like this- 

    class Policy extends AppModel {

            public $belongsTo = 'CloudApp'; 

    }

When I use scaffolding, everything works fine- I am able to multi-select policies for CloudApp that I am saving. 

But when I try to manually save data, associated data in Policy model is not getting saved.

Here is my `add` controller- 

public function add() {

    $this->loadModel('Policy');

    $this->set('policies', $this->Policy->find('list', array(

                'fields' => array('Policy.name')

    )));

    if ($this->request->is('post')) {

        pr($this->request->data);

        $this->CloudApp->saveAll($this->request->data);        }

}

add.ctp looks like this-

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

    ?>

    <fieldset>

        <legend><?php echo __('Add Application'); ?></legend>

        <?php    

        echo $this->Form->input('name');

        echo $this->Form->input('policies', array(

            'multiple' => true

        ));    

        

        ?>

    </fieldset>

    <?php echo $this->Form->end(__('Submit')); ?>

Output of  `pr($this->request->data);` is- 

    Array

    (

        [CloudApp] => Array

            (

                [name] => 123

                [policies] => Array

                    (

                        [0] => 18

                        [1] => 19

                        [2] => 20

                    )

    

            )

    

    )

What am I doing wrong?
