如何使用 get() 在 CakePhp 3 中获取给定 ID 的所有关联数据？

Question

这是我的情况....

1. 我可以根据从 GUI 传递的项目 ID 查看项目详细信息

   public function view($id = null){
   
   $id = $this->request->getData('assetsource_id');
   $assetSource = $this->AssetSources->get($id, [
       'contain' => ['Assets']
   ]);
   
   debug($assetSource);
   die();
   
   $this->set('assetSource', $assetSource);
   $this->set('_serialize', ['assetSource']);
   

2. 当我调试时，我得到以下除了...

   /src/Controller/AssetSourcesController.php (line 64)
   
     object(App\Model\Entity\AssetSource) {
   
     'id' => (int) 18,
     'name' => 'Donated',
     'created_by' => '',
     'assets' => [
   (int) 0 => object(App\Model\Entity\Asset) {
   
       'id' => (int) 1,
       'school_unit_id' => (int) 33,
       'asset_source_id' => (int) 18,
       'asset_description' => 'TOYOTA HILUX',
       'date_of_entry' => object(Cake\I18n\FrozenDate) {
   
           'time' => '2021-05-31T00:00:00+00:00',
           'timezone' => 'UTC',
           'fixedNowTime' => false
   
       },
       'date_of_purchase' => object(Cake\I18n\FrozenDate) {
   
           'time' => '2021-05-31T00:00:00+00:00',
           'timezone' => 'UTC',
           'fixedNowTime' => false
   
       },
       'grn_number' => 'KBHBBH92',
       'name_of_supplier' => 'TOYOTA ZAMBIA',
       'serial_number' => 'YTDIYTFYUFOGOOHH',
       'location' => 'BURSAR',
       'asset_category_id' => (int) 24,
       'asset_group_class_id' => (int) 65,
       'full_asset_number' => 'GGFUYG88',
       'condition_id' => (int) 12,
       'asset_status_id' => (int) 14,
       'value' => '400,000',
       'custodian_name' => 'JOE BANDA',
       'custodian_phone' => '0966010101',
       'custodian_email' => 'bursar@unza.zm',
       'created' => object(Cake\I18n\FrozenTime) {
   
           'time' => '2021-05-31T07:26:31+00:00',
           'timezone' => 'UTC',
           'fixedNowTime' => false
   
       },
       'modified' => object(Cake\I18n\FrozenTime) {
   
           'time' => '2021-05-31T07:26:31+00:00',
           'timezone' => 'UTC',
           'fixedNowTime' => false
   
       },
       'created_by' => 'admin',
       '[new]' => false,
       '[accessible]' => [
           '*' => true,
           'id' => false
       ],
       '[dirty]' => [],
       '[original]' => [],
       '[virtual]' => [],
       '[errors]' => [],
       '[invalid]' => [],
       '[repository]' => 'Assets'
   
   }
      ],
        '[new]' => false,
        '[accessible]' => [
        '*' => true,
        'id' => false
      ],
        '[dirty]' => [],
        '[original]' => [],
        '[virtual]' => [],
        '[errors]' => [],
        '[invalid]' => [],
        '[repository]' => 'AssetSources'
      }
   

3. 除了我将结果传递给 view.ctp 时，school_unit_id、asset_source_id、asset_category_id、asset_group_class_id、condition_id、asset_status_id 都显示保存在资产表中的相应 ID。

                                   <?php foreach ($assetSource->assets as $assets) : ?>
                                       <tr>
                                           <td><?php echo $i++ ?></td>
                                           <td><?= h($assets->school_unit_id) ?></td>
                                           <td><?= h($assets->asset_description) ?></td>
                                           <td><?= h($assets->date_of_purchase) ?></td>
                                           <td><?= h($assets->name_of_supplier) ?></td>
                                           <td><?= h($assets->location) ?></td>
                                           <td><?= h($assets->condition_id) ?></td>
                                           <td><?= h($assets->value) ?></td>
                                           <td><?= h($assets->custodian_name) ?></td>
   
                                       </tr>
                                   <?php endforeach; ?>
   

4. 如何显示相应的显示字段而不是 ID？注意asset_sources 表只关联到assets 表。然后assets 表关联到school_units、asset_sources、asset_categories、asset_group_classes、conditions、asset_status 表。在我看来。我想看到school_unit_name 而不是school_unit_id。注意：我使用烘焙命令来创建应用程序。

谢谢

阅读收容措施。它会让你包含任何你想要的东西。 'contain' => ['Assets' => ['SchoolUnits']] 应该在这里工作，然后你可以在你的视图中使用 $assets->school_unit->name 或类似的东西。
