我正在使用cakephp 2.3.4。我有一个数据库表供应商和一个表产品。他们彼此之间都有多对多的关系。我的问题是，一旦为包含某些产品的供应商返回了数组，那个数组格式就不那么时髦了，我很难正确地解决它。这是我得到的
供应商模型：
<?php
App::uses('AppModel', 'Model');
class Vendor extends AppModel {
/**
* belongsTo associations
*
* @var array
*/
public $actsAs = array('Search.Searchable');
public $filterArgs = array(
array('name' => 'vendor_name', 'type' => 'query','method'=>'filterVendor'),
array('name' => 'is_finalized', 'type' => 'string'),
);
public $belongsTo = array(
'Product' => array(
'className' => 'Product',
'foreignKey' => 'product_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
/**
* hasMany associations
*
* @var array
*/
public $hasMany = array(
'Product' => array(
'className' => 'Product',
'foreignKey' => 'vendor_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
/* public function __construct($id = false,$table = null,$ids = null) {
$this->statuses = array(
'open' => __('Open',true),
'closed' => __('Closed',true),
);
$this->categories = array(
'bug' => __('bug',true),
'support' => __('support',true),
'technical' => __('technical',true),
'other' => __('other',true),
);
parent::__construct($id,$table,$ids);
}
*/
public function filterVendor($data = array()) {
$filter = $data['vendor_name'];
if(empty($filter))
{
return array();
}
$cond = array(
'OR' => array(
$this->alias . '.vendor_name LIKE' => '%' . $filter . '%',
));
return $cond;
}
}
问题是，在我的视图文件中，我得到了像这样的产品数组
<?php
$i = 0;
Debugger::dump($vendor['Product']);
foreach ($vendor['Product'] as $product):
if ( !is_null($product['id'])):
Debugger::dump($product['id']);
?>
<tr>
<td><?php echo $product['id']; ?></td>
<td><?php echo $product['vendor_id']; ?></td>
<td><?php echo $product['sku']; ?></td>
<td><?php echo $product['product_name']; ?></td>
<td><?php echo $product['product_weight']; ?></td>
<td><?php echo $product['product_dimenssions']; ?></td>
<td><?php echo $product['product_quantity']; ?></td>
<td><?php echo $product['product_quantity_sold']; ?></td>
<td><?php echo $product['product_quantity_returned']; ?></td>
<td><?php echo $product['product_cost_price']; ?></td>
<td><?php echo $product['product_list_price']; ?></td>
<td><?php echo $product['product_map_price']; ?></td>
<td><?php echo $product['product_special_instructions']; ?></td>
<td><?php echo $product['is_fragile']; ?></td>
<td><?php echo $product['is_downloadable']; ?></td>
<td><?php echo $product['is_always_in_stock']; ?></td>
<td class="actions">
<?php echo $this->Html->link(__('View'), array('controller' => 'products', 'action' => 'view', $product['id'])); ?>
<?php echo $this->Html->link(__('Edit'), array('controller' => 'products', 'action' => 'edit', $product['id'])); ?>
<?php echo $this->Form->postLink(__('Delete'), array('controller' => 'products', 'action' => 'delete', $product['id']), null, __('Are you sure you want to delete # %s?', $product['id'])); ?>
</td>
</tr>
<?php endif; endforeach; ?>
并且上面的调试器语句将为我们提供此

你看到数组的格式非常混乱，因为实际的产品子数组不是在属性名称下开始，而是它只是以int开头，然后还有一些其他属性包含在数组的结构中。
我的问题是，蛋糕正在做什么，或者我可以解决这个问题。如果我可以怎么样？ 感谢
答案 0 :(得分：4)
在cakephp中，我们可以使用不同的结构实现多对多（HABTM）。对于HABTM，您需要3个表
你还需要一个像
这样的关系定义在产品型号中
public $hasAndBelongsToMany = array(
'Vendor' => array(
'className' => 'Vendor',
'joinTable' => 'products_vendors',
'foreignKey' => 'product_id',
'associationForeignKey' => 'vendor_id',
'unique' => 'keepExisting'
)
);
在供应商模型中
public $hasAndBelongsToMany = array(
'Product' => array(
'className' => 'Product',
'joinTable' => 'products_vendors',
'foreignKey' => 'vendor_id',
'associationForeignKey' => 'product_id',
'unique' => 'keepExisting'
)
);
这会给你正确的结果。
