如何在phalcon框架中連接多個數據庫

Question

我必須數據庫即master和xyz，因爲我需要在應用程序中連接兩個數據庫。 所以有可能在一個應用程序中連接多個數據庫，然後是如何。

Answer 1

設置你的DI連接：

//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" => "" 
    )); 
}); 

在你的模型選擇連接：

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

Answer 2

另一種方式來做到這一點，使用相同的配置

//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" => "" 
    )); 
}); 

在你模型集

public function initialize() 
{ 
    $this->setReadConnectionService('dbSlave'); 
    $this->setWriteConnectionService('dbMaster'); 

    $this->setSource('table_name'); 
} 

如果你使用事務，記得在噴油器的依賴性改變

$di->set('dbMaster' .... 

對於

$di->setShared('dbMaster'.... 

，剩下的就是同
