我的应用程序有一个主数据库和许多辅助数据库。我有每个数据库 2 GB 的限制，所以我必须有多个数据库。
数据必须保存在主数据库和许多辅助数据库之一中。从主数据库，我知道要保存数据的辅助数据库。
我的数据库不完全相同，有细微的差别。我为主数据库创建了一个模型，为辅助数据库创建了另一个模型。
这是错误：
CException
SlaveUrl and its behaviors do not have a method or closure named "findByUrl".
这是我正在与之抗争的路线：
$record = SlaveUrl::model()->findByUrl($query);
它在这段代码中找到：
