CakePHP 2.1使用DBMS功能時查找命令的奇怪答案格式

Question

我有以下搜索查詢（需要有一個帖子的年/月和slu in以便在添加評論後正確重定向）。

$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); 

那是什麼我得到Debugger::dump($post);：

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

會不是更合乎邏輯：

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

在您需要的信息， '出版' 的情況是一個自定義的發現類型，定義如下：

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; 
} 

EDIT

我發現，當僅使用Post.date_published YEAR（Post.date_published）代替，Post.date_published也出現在後陣列中，就如同蛞蝓一樣。爲什麼使用MYSQL函數改變這個？

Answer 1

這是CakePHP中，當你在查詢中添加字段會發生什麼，我相信你可以讓他們與的MyModel__MyField正確的別名命名約定的主要數據陣列的一部分：

$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']) 
    );
