Question

我一直致力于下面链接的介绍，并且已经能够完成以前的步骤，但是当涉及到运行generate.php文件时，我收到有关dsn的错误。是否有关于更改dsn的遗漏步骤？ http://www.doctrine-project.org/projects/orm/1.2/docs/manual/introduction-to-models/en#introduction-to-models

Fatal Error with Doctrine while using generate.php

我在这里看到了类似的问题（上面的链接）和generate.php文件，但提供的解决方案和错误略有不同，在我的情况下不起作用。将dsn字符串更改为 $ conn = Doctrine_Manager :: connection（'mysql：// sonint99：C2sHF9Zxq3ULXCTV@127.0.0.1/doctrine'）;也不起作用。我现在收到这个错误。

Answer 1

Docs相当奇怪，因为他们提到了::connection()方法的PDO。该方法甚至没有在网站上的教程中使用;）

连接的正确呼叫可能就像

$db['dsn'] = "mysql://user:password@localhost/database"; //use localhost instead of 127.0.0.1
$conn = Doctrine_Manager::connection($db['dsn'], 'con_name');

与generate.php文件的Doctrine dsn错误
