Question

我有一个非常奇怪的错误，我无法理解。我开始一个新项目抛出zf.sh. 现在，当我尝试从数据库中获取数据时，我在尝试从中获取数据时创建的每个表都会出错。

在这种情况下，我尝试获取数据库中存在的用户。

错误：

            ->setCompanyID($row->companyID);
        return $user;
    }

有人可以帮助我，看看代码有什么问题吗？谢谢！

Answer 1

问题在于您不是引导db资源。通过在Bootstrap中创建一个名为_initDb的方法，告诉Bootstrap您的方法将处理db资源引导程序。因此，Bootstrap永远不会调用$this->bootstrap('db')。

如果您尝试使用名称$this->bootstrap('db')在方法中添加_initDb，那么您将获得例外Circular resource dependency detected。

所以，解决方案应该是：

protected function _initMyDb() {
    $this->bootstrap('db');
    $resource = $this->getPluginResource('db');
    $db = $resource->getDbAdapter();
    $db->query('SET CHARACTER SET \'UTF8\'');
}

启动后，您可以开始使用Zend_Db_Table::getDefaultAdapter()

我在我的项目中解决了这个问题，将application.ini的代码块dbAdpter放入标签 production 。

[production]

resources.db.adapter = "mysqli"
resources.db.params.host = "localhost"
resources.db.params.username = "db_user"
resources.db.params.password = "db_pass"
resources.db.params.dbname = "zf_cms"
resources.db.isDefaultTableAdapter = true

[staging : production]

找不到App_Model_DbTable_User的适配器
