我有一个用 cakephp 2.0 开发的网站。我有一个关系HABTM到同一个模型是这样的:
class Product extends AppModel {
public $name = 'Product';
public $useTable = 'products';
public $belongsTo = 'User';
public $actsAs = array('Containable');
public $hasAndBelongsToMany = array(
'Product' => array(
'className' => 'Product',
'joinTable' => 'ingredients_products',
'foreignKey' => 'product_id',
'associationForeignKey' => 'ingredient_id',
'unique' => false
)
);
}
我想用这样的简单形式将记录保存到我的视图中:
echo $this->Form->create('IngredientProduct', array ('class' => 'form', 'type' => 'file'));
foreach ($product as $prod) {
echo '<div>'.$prod['ProductAlias']['alias'].'</div>';
echo $this->Form->input('IngredientProduct.product_id', array ('type'=>'text', 'value'=> $prod['ProductAlias']['id'], 'label'=> false, 'id' => 'id'));
}
$select = '<select name="data[IngredientProduct][ingredient_id]" id="[IngredientProductIngredientId">';
foreach ($other_product as $prod2) {
$select .= '<option value="'.$prod2['ProductAlias']['id'].'">'.$prod2['ProductAlias']['alias'].'</option>';
}
$select .= '</select><br>';
echo($select);
echo $this->Form->submit('Collega', array('id'=>'link_product'));
echo $this->Form->end();
在我的控制器中,我以这种模式保存:
if ($this->Product->saveAll($this->request->data)){
$this->Session->write('flash_element','success');
$this->Session->setFlash ('Prodotto collegato con successo.');
//$this->redirect(array('action'=>'edit',$alias));
}
else{
$this->Session->write('flash_element','error');
$this->Session->setFlash('Errore di salvataggio activity');
}
当我要查看数据库时,我看到成分:id 设置良好,但 product_id 为 0。我已经调试了我的 request->data,这是数组:
array(
'IngredientProduct' => array(
'product_id' => '1',
'ingredient_id' => '2'
)
)
我打印了 cakephp 创建的 sql 查询:
INSERT INTO `db`.`ingredients_products` (`product_id`, `ingredient_id`, `modified`, `created`) VALUES ('', 2, '2012-10-09 23:19:22', '2012-10-09 23:19:22')
为什么 product_id 为 null 而不是 1?有人能帮我吗?谢谢
