mysql - 调试工具包显示重复查询

问题描述

我正在做蛋糕教程，一旦我结束，正在查看文章编辑页面内的 Debugkit sql 日志，看起来检索文章数据的查询由于某种原因被重复了。
这是显示两次的查询：

SELECT 
  Articles.id AS `Articles__id`, 
  Articles.user_id AS `Articles__user_id`, 
  Articles.title AS `Articles__title`, 
  Articles.slug AS `Articles__slug`, 
  Articles.body AS `Articles__body`, 
  Articles.published AS `Articles__published`, 
  Articles.created AS `Articles__created`, 
  Articles.modified AS `Articles__modified` 
FROM 
  articles Articles 
WHERE 
  Articles.slug = 'first-post' 
LIMIT 
  1

这是编辑功能：

   public function edit($slug)
    {
        $article = $this->Articles
            ->findBySlug($slug)
            ->contain('Tags') // load associated Tags
            ->firstOrFail();

        if ($this->request->is(['post', 'put'])) {
            $this->Articles->patchEntity($article, $this->request->getData(), [
                // Added: Disable modification of user_id.
                'accessibleFields' => ['user_id' => false]
            ]);
            if ($this->Articles->save($article)) {
                $this->Flash->success(__('Your article has been updated.'));
                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('Unable to update your article.'));
        }
        $tags = $this->Articles->Tags->find('list');

        $this->set('article', $article);
        $this->set('tags', $tags);

    }

查询应该在这一行只执行一次：

 $article = $this->Articles
            ->findBySlug($slug)
            ->contain('Tags') // load associated Tags
            ->firstOrFail();

正确的？

解决方案

有可能，调试工具包被加载了两次。请参阅 bootstrap.php 配置文件。如果有删除它，因为在 3.6 中正在加载 Application.php
