php - 根据条件从数据库中的 2 个表中选择数据 CakePHP

Question

我有两个表Standards和Topics，Standard包含id、user_id、name和主题包含id、user_id、name、school_id。

我想通过用户登录条件从Standards 和Topics 检索数据。所以用户只能看到他们的学校名称。

错误:错误是，它将显示属于所有用户的学校名称，而不仅仅是登录的用户。

我想显示登录的学校名称用户。

这是我的 Controller :

public function admin_subject_list($standard_id = null)
{
    $this->loadModel('Subject');
    $this->Subject->bindModel(array(
                        'belongsTo'=>array(
                            'Standard'
                        ),
                        'hasMany'=>array(
                            'Topic'
                        )
    ),false);

    $standard_data = $this->Standard->find('first',array('conditions'=>array('Standard.id'=>$standard_id)));

    $filters        =   array('Topic.id'=>$this->Auth->user('id'));

    $filter = array('Subject.standard_id'=>$standard_id);
    $data = $this->Subject->find('all',array('conditions'=>$filter));       
    $this->set(compact('data','standard_id','standard_data'));
    $this->set('title_for_layout', __('Standards', true));      
}   

这是我的 View 文件standartd_list.ctp

<?php
    }
    // pr($data);
    $color = array('bg-kypta','bg-green','bg-aqua','bg-uni-n','bg-light-blue','bg-orange','bg-ferozi','bg-light-bluen','bg-light-yellow','bg-teal','bg-maroon');
    foreach($data as $key=>$value)
    {
        $random = rand(0,10);
        $get_subscribe_subject = $this->General->getSubscribeTutor($value['Subject']['id']);
        if(empty($get_subscribe_subject))

Answer 1

您正在使用主题 ID 检查登录用户的 ID。因此，在您的情况下，您需要使用主题的 user_id 检查登录用户的 ID。

public function admin_subject_list($standard_id = null)
{
    $this->loadModel('Subject');
    $this->Subject->bindModel(array(
                    'belongsTo'=>array(
                        'Standard'
                    ),
                    'hasMany'=>array(
                        'Topic'
                    )
    ),false);

    $standard_data = $this->Standard->find('first',array('conditions'=>array('Standard.id'=>$standard_id)));

    $this->Subject->Behaviors->load('Containable');
    $userId = $this->Auth->user('id');
    $filters = array('Subject.standard_id'=>$standard_id);
    $data = $this->Subject->find('all',array('conditions'=>$filters, 'contain' => array('Standard', 'Topic' => array('conditions' => array('Topic.user_id' => $userId))))); 

    $this->set(compact('data','standard_id','standard_data'));
    $this->set('title_for_layout', __('Standards', true));      
}
