錯誤：SQLSTATE [42S22]：未找到列：1054'字段列表'中的未知列'details.id'

Question

使用cakephp-elasticsearch插件來索引和搜索mysql Db。我跟着從這個鏈接教程：

https://github.com/dkullmann/CakePHP-Elastic-Search-DataSource 

我所創建的「詳細信息」模塊：

<?php 
class details extends AppModel { 

    public $useDbConfig = 'index'; 
public $useType = 'details'; 

    public $_mapping = array(
     'name' => array('type' => 'string'), 
     'addr' => array('type' => 'string'), 
     'phno' => array('type' => 'string'), 
     'city' => array('type' => 'string'), 
     'state' => array('type' => 'string'), 

    ); 

    public function elasticMapping() { 
     return $this->_mapping; 
    } 
} 
?> 

開始索引記錄我使用這個命令：

Console/cake Elastic.elastic index details 

即時得到的以下錯誤：

#9 /var/www/cakephp/app/Console/cake.php(37): ShellDispatcher::run(Array)

我沒有任何名爲id的字段..我會做什麼錯誤？請幫幫我！！

Answer 1

所有的數據庫表都需要一個主鍵

，默認情況下，該字段的名稱是id。如果表有不同的主鍵，它需要設置primaryKey屬性，使蛋糕知道它是什麼：

class MyModel extends AppModel { 

    $primaryKey = 'odd'; 

} 

是常規

What mistake i would have done?

有代碼對方失誤的問題，即：

型號名稱是單數

所以，class details - >class detail。

當查找要使用的表時，Cake會自動使用複數形式（details）。

類名是CameBacked

所以class detail - >class Detail

有書中更多有關CakePHP's conventions。

這也隱含文檔中增強了ES plugin，比較問題的CLI調用：

Console/cake Elastic.elastic index details 
           ^lower case plural model name 

與一個在ES插件自述：

Console/cake Elastic.elastic index Contact 
           ^Correct case and singular 

不遵守約定是一種查找不一致行爲的簡單方法。
