错误代码

Question

我正在学习Zend框架的工作，而通过一个教程我跑进了一个找不到Application_Model_DbTable_Users错误的适配器。我似乎无法弄明白。这是我的课程

class Application_Model_Register
 {
private $_dbTable;
private $db;

public function __construct()
{
    $this->_dbTable = new Application_Model_DbTable_Users();

        $parameters =array(
                        'host'     => '127.0.0.1',
                        'username' => 'root',
                        'password' => '******',
                        'dbname'   => 'tutblog',
                                                'adapter'  => 'Pdo_Mysql'
                   );
            try {
                $db = Zend_Db::factory('Pdo_Mysql', $parameters);
                $db->getConnection();
                } catch (Zend_Db_Adapter_Exception $e) {

                } catch (Zend_Exception $e) 
 }
 public function createUser($array)
{   var_dump($array);
    $_dbTable = new Application_Model_DbTable_Users();
    $this->_dbTable->insert($array);
    //insert('array') SQL commands-> form zen_db_table_abstract
}

DBtable用户的班级

class Application_Model_DbTable_Users extends Zend_Db_Table_Abstract
{

    protected $_name = 'users';
protected $_primary ='id';
protected $_password= 'password';
}

其他用户类为空。

的IndexController

public function indexAction()
{   
    $register =  new Application_Model_Register();
$register ->createUser(array( 'name' => 'becky',
                      'age'  => 25,
              'password' => 'somepw'
                 )2);*/
}

我的ini文件

[production]
phpSettings.display_startup_errors = 2
phpSettings.display_errors = 2
includePaths.library = APPLICATION_PATH "/../library"
bootstrap.path = APPLICATION_PATH "/Bootstrap.php"
bootstrap.class = "Bootstrap"
appnamespace = "Application"
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.params.displayExceptions = 0
resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts/"

resources.db.params.adapter_ = "PDO_MYSQL"
resources.db.params.host ='localhost'
resources.db.params.dbname ='tutblog'
resources.db.params.username = "root"
resources.db.params.password = "password"
resources.db.isDefaultTableAdapter = true



[staging : production]


phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1

[development : production]
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1
resources.frontController.params.displayExceptions = 1

resources.db.params.adapter_ = "PDO_MYSQL"
resources.db.params.host ='localhost'
resources.db.params.dbname ='tutblog'
resources.db.params.username = "root"
resources.db.params.password = "password"
resources.db.isDefaultTableAdapter = true

`提前谢谢你们，我真的不知道从哪里开始新的框架。我用谷歌搜索了所有东西，即将重新启动啧啧，但我觉得再次陷入这个问题。

日Thnx

如果我没记错的话，你需要告诉应用程序始终使用db连接作为Zend_Db_Table类的默认连接。

尝试在数据库初始化之后放置此行： Zend_Db_Table::setDefaultAdapter($db)

我认为你应该在实例化Zend_Db_Table类之前执行此操作，因此将Application_Model_Register :: __ construct（）更改为：

public function __construct()
{
    $parameters =array(
                    'host'     => '127.0.0.1',
                    'username' => 'root',
                    'password' => '******',
                    'dbname'   => 'tutblog',
                                            'adapter'  => 'Pdo_Mysql'
               );
     try {
         $db = Zend_Db::factory('Pdo_Mysql', $parameters);
         $db->getConnection();
     } catch (Zend_Db_Adapter_Exception $e) {

     } catch (Zend_Exception $e) { 
     }
     Zend_Db_Table::setDefaultAdapter($db);
     $this->_dbTable = new Application_Model_DbTable_Users();
}

在你的构造函数中，你似乎试图初始化一个新的db适配器。 DbTable模型已使用 application.ini 中设置的适配器，因此无需设置新适配器。另外我不确定这是否重要，但手册中适配器的语法是 * Pdo_Mysql *
如果您需要使用多个适配器，那么使用application.ini中的multiDb资源会更加一致。

所有人都说，使用DbTable模型的模型的构造函数通常看起来类似于：

  //This class is currently intended to be extended by concrete mappers
  protected $_tableGateway = NULL;

  protected $_identityMap = array();

 //this constructor typically provides the option to pass in a DbTable model
 // or a string value for the table name that would instantiate a Zend_Db_Table_Abstract
 public function __construct(Zend_Db_Table_Abstract $tableGateway = NULL) {

        if (is_null($tableGateway)) {
            //_tablename is the string value of the table, supplied by the concrete mapper
            $this->_tableGateway = new Zend_Db_Table($this->_tableName);
        } else {

            $this->_tableGateway = $tableGateway;
        }
    }

 protected function _getGateway() {

        return $this->_tableGateway;
    }

/**
     * findAll() is a proxy for the fetchAll() method and returns
     * an array of entity objects
     *
     * @return array returns an array of row objects
     */
    public function findAll() {

        $select = $this->_getGateway()->select();

        $rowset = $this->_getGateway()->fetchAll($select);
        $entities = array();
        foreach ($rowset as $row) {
            $entity = $this->_createEntity($row);
            $entities[] = $entity;
        }
        return $entities;
    }

    /**
     * Abstract method to be implemented by concrete mappers.
     */
    abstract protected function _createEntity($row);
}

我提供了一些方法来帮助演示如何使用Zend_Db_Table_Abstract接口来编写查询。

我发现这些链接在尝试解决这些问题时很有帮助。

当文件移动到开发服务器但我在本地服务器上运行时，我也遇到了同样的问题。然后我就按照文件命名约定。

以下所有内容，请注意小写/大写
请注意，models文件夹是复数，而类是模型单数
确保该类名为Application_Model_DbTable_Albums
确保该文件名为Albums.php，并位于名为application / models / DbTable的文件夹中

你必须经历它并检查文件是否正确命名（例如，模型的Users.php）。

它解决了我的问题。也许是你的。

祝你好运。
