cakephp - Cakephp を使用すると、モデルのオプションがビューに表示されない

Question

私は CakePhp を初めて使用し、add.ctp に表示するパブリック変数の呼び出しに問題があります。

以下は、モデルフォルダー内の私のprovince.phpです。

<?php
App::uses('AppModel', 'Model');
App::uses('Sanitize', 'Utility');
/**
 * Place Model
 *
 */
class Province extends AppModel {

/**
 * Display field
 *
 * @var string
 */

    public $continent = array(
        'AF' => 'Africa',
        'AS' => 'Asia',
        'EU' => 'Europe',
        'NA' => 'North America',
        'SA' => 'South America',
        'OC' => 'Oceania',
        'AN' => 'Antartica'
    );

    public $countries = array(
            'Asia' => array(
                'AF' => 'Afghanistan',  
                'AM' => 'Armenia',  
                'AZ' => 'Azerbaijan',   
                'BH' => 'Bahrain',
                'BD' => 'Bangladesh',
                'BT' => 'Bhutan',
                'BN' => 'Brunei',   
                'KH' => 'Cambodia',
                'CN' => 'China',
                'CX' => 'Christmas Island',
                'CC' => 'Cocos Islands',
                'IO' => 'Diego Garcia',
                'GE' => 'Georgia',
                'HK' => 'Hong Kong',
                'IN' => 'India',
                'ID' => 'Indonesia',
                'IR' => 'Iran',
                'IQ' => 'Iraq',
                'IL' => 'Israel',
                'JP' => 'Japan',
                'JO' => 'Jordan',
                'KZ' => 'Kazakhstan',
                'KP' => 'North Korea',
                'KR' => 'South Korea',
                'KW' => 'Kuwait',
                'KG' => 'Kyrgyzstan',
                'LA' => 'Laos',
                'LB' => 'Lebanon',
                'MO' => 'Macau',
                'MY' => 'Malaysia',
                'MV' => 'Maldives',
                'MN' => 'Mongolia',
                'MM' => 'Myanmar',
                'NP' => 'Nepal',
                'OM' => 'Oman',
                'PK' => 'Pakistan',
                'PS' => 'Palestine',
                'PH' => 'Philippines',
                'QA' => 'Qatar',
                'SA' => 'Saudi Arabia',
                'SG' => 'Singapore',
                'LK' => 'Sri Lanka',
                'SY' => 'Syria',
                'TW' => 'Taiwan',
                'TJ' => 'Tajikistan',
                'TH' => 'Thailand',
                'TR' => 'Turkey',
                'TM' => 'Turkmenistan',
                'AE' => 'United Arab Emirates',
                'UZ' => 'Uzbekistan',
                'VN' => 'Vietnam',
                'YE' => 'Yemen',
            )
        );

    public $belongsTo = array(
        'Image' => array(
            'className' => 'Image',
            'foreignKey' => 'image_id'
        ),
    );

}

そして、ここにプロヴィンスコントローラーの私のコードがあります:

<?php
App::uses('AppController', 'Controller');
App::uses('Sanitize', 'Utility');
/**

 *
 * Override this controller by placing a copy in controllers directory of an application

                );

                if(UserPerm::provinces_attribute()) { // base on places_attribute search for this
                    $image_data['source_url'] = $this->request->data['Province']['img_source'];

        }

        $this->request->data['Province']['name'] = Sanitize::clean($this->request->data['Province']['name']);

ここに私のビュー add.ctp があります:

<div class="places form box-rounded">
<div class="pull-right">
    <?php echo $this->Html->link('View', 'view/' .$this->request->data['Province']['id']) ?>
</div>
<?php if(!empty($this->request->data)): ?>
<h2><?php echo __('Edit Province'); ?></h2>
<?php else: ?>
<h2><?php echo __('New Province'); ?></h2>
<?php endif; ?>

<?php 

    echo $this->Form->create('Province', array('type' => 'file', 'inputDefaults' => array('class' => 'form-control', 'div' => array('class' => 'col-sm-3'))));

    echo "<div class='form-group row'>" . $this->Form->input('name') . "</div>"; 
    echo "<div class='form-group row'>" . $this->Form->input('country', array('options' => $countries,
        'label' => _('Country'),
    )) . "</div>";

    debug($countries); exit;
    echo "<div class='form-group row'>" . $this->Form->input('region') . "</div>";
?>

    <fieldset>
        <legend>Image</legend>
        <?php
        echo '<div class="row"><div class="col-sm-12">Current: ';
        if (isset($this->request->data['Province']['image_id']) && $this->request->data['Province']['image_id']) {
            $url = $s3->get_url($this->request->data['Image']['filename'], 'preview');
            echo $this->Html->image($url, array("class" => 'img-rounded')); 
        }
        echo "</div></div>";
        ?>
        <?php
        echo "<div class='form-group row'>" . $this->Form->input('img', array(
            'label' => __('Upload'),
            'type' => 'file',
            'class' => ''
        )) . "</div>";
        echo "<div class='form-group row'>" . $this->Form->input('img_title', array(
            'label' => __('Image Title'),
            'value' => @$this->request->data['Image']['title']
        )) . "</div>";
        echo "<div class='form-group row'>" . $this->Form->input('img_desc', array(
            'label' => __('Describe'),
            'value' => @$this->request->data['Image']['description']
        )) . "</div>";

        ?>
        <fieldset>
            <legend>Image Attribution</legend>
        <?php
        echo "<div class='form-group row'>" . $this->Form->input('img_source', array(
            'label' => __('Source URL'),
            'value' => @$this->request->data['Image']['source_url']
        )) . "</div>";
        echo "<div class='form-group row'>" . $this->Form->input('img_source_name', array(
            'label' => __('Source Name'),
            'value' => @$this->request->data['Image']['source_name']
        )) . "</div>";
        ?>
        </fielset>

    </fielset>

    <?php 
        $options = array(
            'label' => 'Save',
            'escape' => false,
            'class' => 'btn btn-success'
        ); 
    ?>

    <?php echo $this->Form->end($options); ?>

そして、ここに私が得ているものがあります:

'<div class="col-sm-3"><label for="ProvinceCountry">Country</label><select name="data[Province][country]" class="form-control" maxlenght="15" id="ProvinceCountry">

'

オプションが表示されません。ここで何か不足していますか？モデルの $countries 変数を選択ボックスのオプションとして表示したいと考えています。ありがとうございました。
