我有4个模型:
Item-----hasMany---->详情
项目-----hasMany---->收藏
项目-----hasMany---->类别
如何找到所有具有 Favourite.member_id = '8' 和 Category.item_category_id = '1' 的项目
这是我的项目模型关系:
public $hasMany = array(
'Detail' => array(
'className' => 'Detail',
'foreignKey' => 'item_id',
'dependent' => true,
'conditions' => '',
'order' => 'created DESC',
),
'Category' => array(
'className' => 'Category',
'foreignKey' => 'item_id',
'dependent' => true,
'conditions' => '',
'order' => 'created DESC',
),
'Favorite' => array(
'className' => 'Favorite',
'foreignKey' => 'item_id',
'dependent' => true,
'conditions' => '',
'order' => 'created DESC',
)
);
我使用了这个查询(),没关系:
$this->set('test',$this->Item->query("SELECT items.*
FROM items, categories, favourites
WHERE items.id = items_item_categories.item_id
AND items.id = favorites.item_id
AND categories.item_category_id = 1 AND favourites.member_id = 8"));
但是我不喜欢用query(),我把它改成find(),好像不太好:
$this->set('test',$this->Item->find('all', array(
'contain'=>array(
'ItemDetail',
'Category'=>array('conditions'=>array('Category.item_category_id'=>1)),
'Favorite'=>array('conditions'=>array('Favorite.member_id'=>8)));
