問題描述

我創(chuàng)建了一個簡單的datasource:

// app/Model/Datasource/FeedSource.php

App::uses('DataSource', 'Model/Datasource');

class FeedSource extends DataSource {
    public function abcd() {
        echo 'Hello World!';
    }
}

在我的database.php中:

public $feed = array(
    'datasource' => 'FeedSource'
);

在 Feeda 模型中:

class Feeda extends AppModel {
    public $useTable = false;
    public $useDbConfig = 'feed';
}

在list控制器中:

$this->loadModel('Feeda');
$this->Feeda->abcd();

但是，它返回一個致命錯誤:

But, it returns a fatal error:

Error: Call to undefined method FeedSource::query()

如何解決?

謝謝...

推薦答案

也許你的意思是 DboSource 而不是 DataSource.

Perhaps you meant DboSource instead of DataSource.

DataSource 沒有方法查詢，DboSource 有.將您的代碼更新為:

DataSource has no method query, DboSource does. Update your code to look like:

App::uses('DboSource', 'Model/Datasource');
class FeedSource extends DboSource {}

看起來這不是問題.在 Model 中有一個神奇的 __call 方法，它調(diào)用$this->getDataSource()->query($method, $params, $this); 來源你需要自己實現(xiàn)這個.

Looks like that is not the issue. In the Model there is a magic __call method which calls $this->getDataSource()->query($method, $params, $this); Source You need to implement this yourself.

class FeedSource extends DataSource {
    public function abcd() {
        echo 'Hello World!';
    }

    public function query($method, $params, $Model) {
        // you may customize this to your needs.
        if (method_exists($this, $method)) {
            return call_user_func_array(array($this, $method), $params);
        }
    }
}
