Mysql中的关系问题，教义得到此错误：Doctrine_Table_Exception：未知的关系别名Model_Training

问题描述

| 我对教义中的关系有疑问。适用于MysqL数据库。使用关系下载数据时会发生此问题，引发此错误：Doctrine_Table_Exception：未知关系别名Model_Training 请帮助我厌倦它，有几天我坐在上面，却什么也没有发生，谷歌也没有找到任何东西。 这是检索数据的代码：

$daTarows = Doctrine_Query::create()
                    ->from(\'Model_Training a\')->where(\'a.idTrainings = ?\',$this->_getParam(\'id\'))
                    ->leftJoin(\'a.Model_TrainingBonuse ac\')
                    ->leftJoin(\'a.Model_Bonuse ad\')
                    ->fetchArray();

具有Schema.yml文件的教义模型的形成：

解决方法

        您的schema.yml文件中没有\\“ Model_Training \\\”表定义…尽管\\\\\\“培训\\\\\\\\\\\”别名类\或\\\“外部别名\”您在schema.yml中指定的元素，则使用表定义的名称。因此，请使用\“ Training \”（而不是\“ Model_Training \”）（这也适用于\“ Model_Bonuses \”以及其他）。
