Symfony和Sonata的ReflectionException，“類不存在”

Question

我在試圖讓我的實體適合Sonata Admin Bundle時遇到了問題。 我有5個實體，在捆綁中精心列出和查看，但我無法編輯或創建新條目。

當我嘗試編輯或創建時，我收到一個ReflectionException錯誤：

類不存在

我試圖解決這個問題，以操作名稱空間（在管理員文件的同一名稱空間中移動控制器，或左右）或調整管理控制器，以告訴它我的實體（“ - >添加（'個人'， 'entity'，array（'class'=>'Platform \\ ProjectBundle \\ Entity \\ Individual'））“而不是 - > add（'individual'））。

我的實體名為Biosample。 這是實體文件：

這是管理員控制器：

    <?php

namespace Platform\ProjectBundle\Controller;

use Sonata\AdminBundle\Controller\CRUDController as Controller;
use Platform\ProjectBundle\Entity\Biosample;

class BiosampleAdminController extends Controller
{

}

Answer 1

好吧，這個錯誤的原因是教程中的錯誤復制/粘貼。

在Admin類中，函數configureFormFields包含一個嚴重描述的字段“描述”。

->with('Description')
                ->add('description', 'sonata_type_model', array('multiple' => false))
            ->end()

我不得不將其替換為：

  ->with('Description')
                ->add('description')
            ->end()

我發現自動Admin Class骨架生成是Sonata Admin Bundle的一個功能。 為了自動生成，執行：

php app / console sonata：admin：generate

然后輸入實體的完整路徑，在此示例中：

平台\\ ProjectBundle \\實體\\生物標本

管理包將解析您的實體並：

• 生成Admin類文件
• 在應用程序包的service.yml中添加一個條目
• 生成可選的CRUD控制器

我猜這應該是首先使用sonata admin bundle開始的首選方法。

Answer 2

我有同樣的問題，並且由於一個我忽略的原因，不是在過去的項目中我完全相同...經過一個小時的搜索，我意識到我的表'fos_user_user_group'尚未創建，映射是沒有創建。 所以我的解決方案只是覆蓋我的實體User的groups屬性，以便定義Doctrine ORM Mapping：

/**
 * The User can have many groups.
 * @ORM\ManyToMany(targetEntity="Group")
 * @ORM\JoinTable(name="fos_user_user_group",
 *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="group_id", referencedColumnName="id")}
 *      )
 */
protected $groups;

之后，學說：schema：update --force，問題解決了;）

Answer 3

如果你像我一樣，並首先創建數據庫，然后通過控制台創建yml文件，然后從那些類創建，那么你的注釋是無用的。

Sonata使用的是yml而不是注釋。 它們存在並且似乎有效，但它們卻沒有。 要使“類不存在”消息，請檢查您的yml定義所說的內容。 我需要在那里添加關系和實體類。

如果這確實是您出錯的原因，您可能希望通過刪除或移動其他地方的yml或xml模板來激活注釋（.. \\ Resources \\ config \\ doctrine）。
