Cakephp 中的多对多关系

Question

我已经有了徽章、用户和 badges_users table。我想在徽章控制器中构建一个 list() 来列出会话用户拥有的所有徽章。到目前为止，我得到了这个，我不知道如何进行。它必须与分页器组件一起工作

public function list() {
    $this->Badge->recursive = 0;        
    $this->paginate['conditions'] = array('user_id' => $this->Auth->user('id'));            
    $this->Paginator->settings = $this->paginate;           
    $this->set('badges', $this->paginate());
}

Answer 1

user_id 字段仅在 badge_users table 中可用，在徽章 table 中不可用，因此您应该在 badge_users 控制器中构建 list()，并且在分页设置中为徽章模型定义包含参数。

//in badges_users controller
public function list() {
    $this->BadgesUsers->recursive = 2;      
    $this->paginate['conditions'] = array('user_id' => $this->Auth->user('id'));    

//contain parameter
$this->paginate['contain'] = array('Badges');

    $this->Paginator->settings = $this->paginate;           
    $this->set('badges', $this->Paginator->paginate('BadgesUsers));
}
