Symfony + Propel：設置連接整理

我正在使用與Propel 1.6.7集成的Symfony 2.1.6框架作爲數據庫ORM，通過MySQL服務器5.5.28，我有問題需要將數據庫整理設置爲utf8_unicode_ci。Symfony + Propel：設置連接整理

我應用程序/配置/ config.yml：

... 
propel: 
    dbal: 
     driver:    %database_driver% 
     user:     %database_user% 
     password:    %database_password% 
     dsn:     "%database_driver%:host=%database_host%;dbname=%database_name%;charset=%database_charset%" 
     options: 
      MYSQL_ATTR_INIT_COMMAND: "SET NAMES utf8 COLLATE utf8_unicode_ci" 
     attributes:   {}

沒有options它的工作原理，但字符集（參數在應用程序/配置/ parameters.yml已定義）問題（MySQL默認爲utf8_general_ci歸類，但數據庫模式定義爲utf8_unicode_ci）。如果我使用options作爲波輪/ Symfony的上面提高了一堆異常：

我知道，我可以改變my.cnf中直接從服務器配置定義MySQL的默認排序規則，但我需要將此設置爲運行時...我錯過了什麼嗎？我應該如何設置MYSQL_ATTR_INIT_COMMANDapp/config/config.yml？

如果你看到源代碼here，

$value = $optiondata['value']; // this is line no 275 
if (is_string($value) && strpos($value, '::') !== false) { 
    if (!defined($value)) { 
     throw new PropelException("Invalid PDO option/attribute value specified: ".$value); 
    } 
    $value = constant($value); 
}

其預期的‘在選項數據值’鍵，所以嘗試這

propel: 
    dbal: 
     driver:    %database_driver% 
     user:     %database_user% 
     password:    %database_password% 
     dsn:     "%database_driver%:host=%database_host%;dbname=%database_name%;charset=%database_charset%" 
     options: 
      MYSQL_ATTR_INIT_COMMAND: { value: "SET NAMES utf8 COLLATE utf8_unicode_ci" } 
     attributes:   {}

或者

，還可以定義查詢，其中有被執行後，立即打開連接

propel: 
    dbal: 
     default_connection:   default 
     connections: 
      default: 
       # ... 
       options: 
        ATTR_PERSISTENT: false 
       attributes: 
        ATTR_EMULATE_PREPARES: true 
       settings: 
        charset:  { value: UTF8 } 
        queries:  { query: 'INSERT INTO BAR ('hey', 'there')' }

關於你改變my.cnf的重點，如果你要使用的數據庫只需要特定的排序規則設置，那麼我認爲在使用命令「create」創建DB時，最好覆蓋排序規則設置數據庫DB_NAME CHARACTER SET UTF8 COLLATE utf8_unicode_ci「，而不是通過編輯全局改變它的my.cnf
