Question

我有以下搜索查询（需要有一个帖子的年/月和slug，以便在添加评论后进行正确的重定向）。

$settingsForPostQuery = array(
            'fields' => array(
                'Post.slug',
                'YEAR(Post.date_published) as year',
                'MONTH(Post.date_published) as month'
            ),
            'conditions' => array('Post.id' => $this -> request -> params['post_id'])
        );
// unbind post model to fetch only necessary stuff
$this -> Comment -> Post -> unbindModel(array(
            'hasMany' => array('Comment'),
            'hasAndBelongsToMany' => array('Tag'),
            'belongsTo' => array('Category')
));

$post = $this -> Comment -> Post -> find('published', $settingsForPostQuery);

这就是Debugger::dump($post);所得到的：

array(
(int) 0 => array(
    'Post' => array(
        'slug' => 'this-is-a-second-test-post-in-the-category-internet'
    ),
    (int) 0 => array(
        'year' => '2012',
        'month' => '6'
    )
)
)

不会更符合逻辑：

array(
(int) 0 => array(
    'Post' => array(
        'slug' => 'this-is-a-second-test-post-in-the-category-internet',
        'year' => '2012',
        'month' => '6'
     )      
  )
)

如果您需要信息，“已发布”是一种自定义查找类型，定义如下：

protected function _findPublished($state, $query, $results = array()) {
    if ($state === 'before') {
        $query['conditions']['Post.is_archived'] = false;
        $query['conditions'][] = 'Post.date_published <= now()';
        return $query;
    }
    return $results;
}

修改

我发现当仅使用Post.date_published而不是YEAR（Post.date_published）时，Post.date_published也会出现在Post数组中，就像slug一样。为什么使用MYSQL函数改变了这个？

这是在查询中添加字段时CakePHP中发生的情况，我相信您可以使用MyModel__MyField的正确别名命名约定使它们成为主数据数组的一部分：

$settingsForPostQuery = array(
        'fields' => array(
            'Post.slug',
            'YEAR(Post.date_published) as Post__year',
            'MONTH(Post.date_published) as Post__month'
        ),
        'conditions' => array('Post.id' => $this -> request -> params['post_id'])
    );
