Cakephp HABTM 不保存

Question

由于某种原因，我无法保存 HABTM 关系，我检查了表单生成并传递给控制器​​的数据结构，还检查了模型中的数据结构，一切似乎都是有序的。任何帮助将不胜感激。

    CREATE TABLE `products_colors` (
      `product_id` char(36) NOT NULL DEFAULT '',
      `color_id` char(36) NOT NULL DEFAULT '',
      PRIMARY KEY (`product_id`,`color_id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

       CREATE TABLE `products_sizes` (
      `product_id` char(36) NOT NULL,
      `size_id` char(36) NOT NULL DEFAULT '',
      PRIMARY KEY (`product_id`,`size_id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

    class ProductsController extends AppController {
        function edit($id = null)
        {
            if(!is_null($id))
            {
                $this->set('productCategories', $this->Product->Category->find('list'));    
                $this->set('sizes', $this->Product->Sizes->find('list'));   
                $this->set('colors', $this->Product->Colors->find('list'));
                $this->Product->contain(array('Sizes', 'Colors'));
                $product = $this->Product->read(null, $id);
                if(!empty($product)) {
                    if($this->RequestHandler->isPut()) {
                        $this->Product->id = $id;
                        $this->Product->begin();
                        $this->Product->set($this->data);
                        debug($this->data); die;
                        //$dbo = $this->Product->getDatasource();
                        //$dbo->fullDebug = true;
                        if($this->Product->save()) {
                            $this->Product->commit();
                            //debug($dbo->_queriesLog); die;
                            $this->Session->setFlash( __('Product updated',true), 'flash_true');
                            $this->redirect(array('action' => 'view', $this->Product->field('slug')));
                  } else {
                            $this->Product->rollback();
                    $this->Session->setFlash(__('Please correct the errors below',true), 'flash_false');
                  }         
                    } else {
                        $this->data = $product;
                    }
                    $this->render('_form');
                    return;
                }
            }   
            $this->redirect(array('controller' => 'categories', 'action' => 'index'));
        }
    }

    class Product extends AppModel 
    {
        var $hasAndBelongsToMany = array(
            'Colors' => array(
                'className' => 'Color',
                'joinTable' => 'products_colors',
                'foreignKey' => 'product_id',
                'associationForeignKey' => 'color_id',
                'unique' => false,
            ),
            'Sizes' => array(
                'className' => 'Size',
                'joinTable' => 'products_sizes',
                'foreignKey' => 'product_id',
                'associationForeignKey' => 'size_id',
            ),
        );
    }


    <?php echo $this->Form->create('Product'); ?>
        <fieldset>
            <legend><?php __('Options') ?></legend>
        <?php echo $this->Form->input('Product.id') ?>

        <?php echo $this->Form->input('Sizes', array('label' => __('Sizes', true), 'multiple' => 'checkbox')) ?>
        <?php echo $this->Form->input('Colors', array('label' => __('Colors', true), 'multiple' => 'checkbox')) ?>

            <?php echo $this->Form->input('Product.name') ?>
            <?php echo $this->Form->input('Product.description') ?>
            <?php echo $this->Form->input('Product.state', array('type' => 'checkbox')) ?>
        </fieldset>
    <?php echo $this->Form->end(__('Submit', true)); ?>

对于面临此问题的其他人，Cakephp 仅支持 INT() 或 CHAR(36) 的 id。使用非标准 ID 也会导致类似的问题。
