我使用cakephp-elasticsearch插件来索引和搜索mysql Db。我从这个链接开始遵循教程:
https://github.com/dkullmann/CakePHP-Elastic-Search-DataSource
我创建了“详情”模块:
<?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;
}
}
?>
要开始索引记录,我使用了以下命令:
Console/cake Elastic.elastic index details
我收到以下错误:
Retrieving data from mysql starting on 1970-01-01 00:00:00
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'details.id' in 'field list'

我没有任何名为id的字段..我会做什么错?请帮帮我!!
答案 0 :(得分:1)
默认情况下,该字段的名称为id
。如果表具有不同的主键,则需要设置primaryKey属性,以便Cake知道它是什么:
class MyModel extends AppModel {
$primaryKey = 'odd';
}
我会做什么错误?
问题中的代码还有其他错误,即:
所以,class details
- &gt; class detail
。
在查找要使用的表时,Cake会自动使用复数下划线形式(details
)。
所以class detail
- &gt; class Detail
本书中有关于CakePHP's conventions的更多信息。
ES plugin的文档中也隐含地强调了这一点,比较了问题中的cli调用:
Console/cake Elastic.elastic index details
^ lower case plural model name
使用ES插件自述文件中的一个:
Console/cake Elastic.elastic index Contact
^ Correct case and singular
不遵循惯例是查找不一致行为的简便方法。
