cakephp HABTM協會

Question

您好我有一個網站在cakephp開發。 我有兩個表： 成分 屬性

表之間的關係是HasAndBelongsToMany（HABTM）。 這是我的模型：

class Ingredient extends AppModel { 
    public $name = 'Ingredient'; 
    public $useTable = 'ingredients'; 
    public $belongsTo = 'User'; 

    public $hasAndBelongsToMany = array (
     'Property' => array (
      'className'    => 'Property', 
      'joinTable'    => 'ingredients_properties', 
      'foreignKey'   => 'ingredient_id', 
      'associationForeignKey' => 'property_id', 
      'unique'    => false 
     ) 
    ); 

} 

class Property extends AppModel{ 
     public $name = 'Property'; 
     public $useTable = 'properties'; 

} 

進入我的IngredientController我要添加新的屬性我已經在這種模式下嘗試：

$this->Ingredient->Property->create(); 
       $this->Ingredient->Property->set('user_id',$this->Session->read('Auth.User.id')); 
       $this->Ingredient->Property->set('ingredient_id',$ing['IngredientAlias']['ingredient_id']); 
       if ($this->Ingredient->Property->save($this->request->data)){ 
        $this->set('flash_element','success'); 
        $this->Session->setFlash ('Ingrediente modificato con successo.'); 
        $this->redirect(array('action'=>'edit',$alias)); 
       } 
       else{ 
        $this->set('flash_element','error'); 
        $this->Session->setFlash('Errore di salvataggio activity'); 
       } 

到數據庫中插入一個新的記錄，但如果我想這是在ingredients_properties（連接表）中插入記錄的成分之間的關​​系，我該怎麼做？在這種模式下就像成分有許多屬性，但不正確。 我該如何解決它？ 或者我必須手動創建記錄到ingredients_properties中？

Answer 1

的解決方案是：

class Ingredient extends AppModel { 
    public $name = 'Ingredient'; 
    public $useTable = 'ingredients'; 
    public $belongsTo = 'User'; 

    public $hasAndBelongsToMany = array (
     'Property' => array (
      'className'    => 'Property', 
      'joinTable'    => 'ingredients_properties', 
      'foreignKey'   => 'ingredient_id', 
      'associationForeignKey' => 'property_id', 
      'unique'    => false 
     ) 
    ); 

} 

class Property extends AppModel{ 
     public $name = 'Property'; 
     public $useTable = 'properties'; 
     public $hasAndBelongsToMany = array (
     'Ingredient' => array (
      'className'    => 'Ingredient', 
      'joinTable'    => 'ingredients_properties', 
      'foreignKey'   => 'property_id', 
      'associationForeignKey' => 'ingredient_id', 
      'unique'    => false 
     ) 
    ); 

}
