db:

//This service returns a MySQL database  $di->set('dbMaster', function() {       return new \Phalcon\Db\Adapter\Pdo\Mysql(array(          "host" => "localhost",          "username" => "",          "password" => "",          "dbname" => ""      ));  });    //This service returns a PostgreSQL database  $di->set('dbSlave', function() {       return new \Phalcon\Db\Adapter\Pdo\Mysql(array(          "host" => "localhost",          "username" => "",          "password" => "",          "dbname" => ""      ));  });

　　

public function initialize()  {      $this->setConnectionService('dbMaster');      //or      $this->setConnectionService('dbSlave');  }

　　

这是给出来的案例，在实际代码环境，用的是默认生成的模板文件。

 

修改配置文件

'database' => array(      'adapter'     => 'Mysql',      'host'        => '127.0.0.1',      'username'    => 'root',      'password'    => 'toor',      'dbname'      => 'db1',      'charset'     => 'utf8',  ),  'db2' => array(      'adapter'     => 'Mysql',      'host'        => '127.0.0.1',      'username'    => 'root',      'password'    => 'toor',      'dbname'      => 'db2',      'charset'     => 'utf8',  ),

　　

$di->set('db', function () use ($config) {      return new DbAdapter($config->database->toArray());  });  $di->set('db2', function () use ($config) {      return new DbAdapter($config->db2->toArray());

　　

在model中使用时，

class user  extends Model  {      public function initialize()      {          $this->setConnectionService('db2');      }  }
