加载烘焙插件模型失败并显示 "Table class for alias Data.History could not be found"

Question

我将模型烘焙到插件中，但无法加载。

我做了什么：

烘焙模型

bin/cake bake model History --connection data --plugin Data --no-rules --no-validation --table elements_history

One moment while associations are detected.

通过$this->addPlugin('Data');
加载了新创建的插件
已验证插件已通过 bin/cake plugin loaded
加载

确认plugins/Data/src/Model/Table/HistoryTable.php存在

root@debian:/var/www/app# cat plugins/Data/src/Model/Table/HistoryTable.php
<?php
declare(strict_types=1);

namespace Data\Model\Table;

use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;
use Cake\Validation\Validator;

 */
class HistoryTable extends Table
{
    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config): void
    {
        parent::initialize($config);

        $this->setTable('elements_history');
        $this->setDisplayField('id');
        $this->setPrimaryKey('id');

        $this->addBehavior('Timestamp');

    }

    /**
     * Returns the database connection name to use by default.
     *
     * @return string
     */
    public static function defaultConnectionName(): string
    {
        return 'data';
    }
}

Added the plugin model 到任意控制器方法：
- 或者$this->loadModel('Data.History');，
- 或TableRegistry::getTableLocator()->get('Data.History');
得到错误：

Table class for alias Data.History could not be found. Cake\ORM\Exception\MissingTableClassException CORE/src/ORM/Locator/TableLocator.php:245

我尝试了什么：

我查看了 CORE/src/ORM/Locator/TableLocator.php 并且我可以记录 _getClassName receives Data.History，但是 returns null.我还记录了它循环通过的 $this->locations，但插件路径不存在：
```
Array
(
    [0] => Model/Table
)
```

将 debug 添加到 CORE/src/Core/App.php right before 它针对 \Model\Table\HistoryTable 针对 _classExistsInBase.

运行测试

debug([
    '$plugin' => $plugin,
    '$name' => $name,
    '$base' => $base,
    '$fullname' => $fullname,
    '_classExistsInBase' => static::_classExistsInBase($fullname, $base),
]);

CORE/src/Core/App.php (line 70)
[
'$plugin' => 'Data',
'$name' => 'History',
'$base' => 'Data',
'$fullname' => '\Model\Table\HistoryTable',
'_classExistsInBase' => false,
]

您知道问题是什么以及如何解决吗？我正在使用 CakePHP 4.2.4 和 Bake 2。

Answer 1

如果是手动创建的插件，您需要确保相应地更新 composer.json 的自动加载器配置并转储自动加载器，否则无法找到您的插件类。

您的本地 Data 插件看起来像这样：

{
    // ...
    "autoload": {
        "psr-4": {
            // ...
            "Data\": "plugins/Data/src/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            // ...
            "Data\Test\": "plugins/Data/tests/"
        }
    }
}

然后转储自动加载器：

composer dumpautoload

如果您使用 bake 创建插件，它会询问您是否应该修改您的 composer.json，如果您允许，它会相应地更新它并转储自动加载器。
