Question

我使用松饼/垃圾cakephp 3. *插件进行软删除。我成功软删除了我的书，但是当我还原时，出现以下错误：

在“书”表中找不到记录

这是我的控制器文件（BooksController.php）：

public function restoreBook($id = null)
{
    $this->request->allowMethod(['post', 'put']);
    $book = $this->Books->get($id);
    if ($this->Books->restoreTrash($book)) {
        $this->Flash->success(__('The book has been restored.'));
    } else {
        $this->Flash->error(__('The book could not be restored. Please, try again.'));
    }

    return $this->redirect(['action' => 'index']);
}

这是我的视图文件（Books / index.ctp），在这里我调用restoreBook函数：

<td class="actions">
                    <?php if (!$book->deleted) : ?>
                    <?= $this->Html->link(__('View'), ['action' => 'view', $book->id]) ?>
                    <?= $this->Html->link(__('Edit'), ['action' => 'edit', $book->id]) ?>

                    <?= $this->Form->postLink(__('Delete'), ['action' => 'delete', $book->id], ['confirm' => __('Are you sure you want to delete # {0}?', $book->id)]) ?>

                    <?php endif; ?>

                    <?php if ($book->deleted) : ?>
                    <?= $this->Form->postLink(__('Restore'), ['action' => 'restoreBook', $book->id], ['confirm' => __('Are you sure you want to restore # {0}?', $book->id)]) ?>
                    <?php endif; ?>

由于数据已被删除（软删除），因此我们需要添加“ withTrashed”来查找数据：

public function restoreBook($id = null)
    {
        $this->request->allowMethod(['post', 'put']);
        //must add 'withTrashed' to find the deleted data
        $book = $this->Books->find('withTrashed')->where(['id =' => $id])->first();
        if ($this->Books->restoreTrash($book)) {
            $this->Flash->success(__('The book has been restored.'));
        } else {
            $this->Flash->error(__('The book could not be restored. Please, try again.'));
        }

        return $this->redirect(['action' => 'index']);
    }

CakePHP 3的Muffin / Trash软删除插件，在restoreTrash时显示错误“找不到书”
