Zend MultiDb资源

Question

我已将我的应用程序配置为使用多个数据库.魔术效果很好.在我的Bootstrap.php中,我已经定义了以下内容:

protected function _initDb()
    {
        $resource = $this->getPluginResource('multidb');
        Zend_Registry::set("multidb", $resource);

    }

在我的application.ini中:

resources.multidb.db1.adapter = mysqli
resources.multidb.db1.host = localhost
resources.multidb.db1.username = user
resources.multidb.db1.password = pass
resources.multidb.db1.dbname = db
resources.multidb.db1.charset= "utf8"
resources.multidb.db1.default= true
resources.multidb.db1.profiler.enabled = true

resources.multidb.oracle.adapter = oracle
resources.multidb.oracle.username = user
resources.multidb.oracle.password = pass
resources.multidb.oracle.charset= "utf8"
resources.multidb.oracle.dbname = "(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(Host = host.example.com) (Port = 1529)) (CONNECT_DATA = (SID = DB)))"
resources.multidb.oracle.profiler.enabled = true

所有这一切都很好.在我的模型中,我通常会在以下内容中执行以下操作init():

$multidb = Zend_Registry::get("multidb");
$this->oracle = $multidb->getDb('oracle');

但我最近想把这部分移到Bootstrap,或者更确切地说是Registry,就像这样:

protected function _initDb()
    {
        $resource = $this->getPluginResource('multidb');
        Zend_Registry::set("multidb", $resource);
        Zend_Registry::set("odb",$resource->getDb('oracle'));
    }

这就是发生的事情:

Fatal error: Uncaught exception 'Zend_Application_Resource_Exception' with message 'A DB adapter was tried to retrieve, but was not configured' in C:\Zend\Apache2\htdocs\Zend\Application\Resource\Multidb.php on line 135

我知道这是一个临时解决方案,但为什么会发生这种情况,以及可能是一个更长期的修复,以便我可以在注册表中设置每个适配器,最好是在bootstrap中？谢谢!

我认为你必须确保multidb资源在其他资源中被引导,以便填充.您可以使用以下内容执行此操作:

protected function _initDb() {         
    $this->bootstrap('multidb');

    $resource = $this->getPluginResource('multidb');         

    Zend_Registry::set("multidb", $resource);         
    Zend_Registry::set("odb",$resource->getDb('oracle'));     
}
