我是 Cake 开发的新手。我面临的问题是在脚本本身中设置数据源。我的 database.php 是；

function __construct() 
{ 
    if(getenv('ENVIRONMENT') == 'staging') {
        $this->default = $this->staging;
    } else {
        $this->default = $this->production;
    }
}

所以，我根据网络服务器的环境设置来设置数据库。自然，php-cli 无法访问此变量。我最终要做的是创建一个 cakephp shell 任务。

class SelectEnvTask extends Shell {

    public function execute() 
    {
        App::Import('ConnectionManager', 'Model');
        $configs = ConnectionManager::enumConnectionObjects();

        if (!is_array($configs) || empty($configs)) {
            $this->out('Error! No database configuration has been found.');
        }

        $connections = array_keys($configs);

        if(!isset($this->args[0])) {
            $this->out('Error! Please enter one of the environment settings as an argument: ' . implode('/', $connections) . 
                "\n\n" . 'eg. ./Console/cake *script_name* *environment*', 2);
            exit(1);
        }

        if(!in_array($this->args[0], $connections)) {
            $this->out($this->args[0] . ' environment could not be found!', 2);
            exit(1);
        }

        //hacky solution until finding a better one
        $models = App::objects('Model');
        foreach($models as $model) {
            ClassRegistry::init($model)->setDataSource($this->args[0]);
        }
    }
}

这可以正常工作，但是正如您在下面的任务中看到的，我获取了所有模型名称并更改了它们的数据库连接，这不是一个好习惯。我也不想在数据库类中设置更多变量，并希望在 shell/tasks 中处理这些变量。

有没有更优雅的方法来实现这一点？

谢谢，

Here is a far more elegant solution. Add the following method to your shell or task, and then execute it whenever you need to in order to change your data profile (listed in app/Config/database.php) on the fly:

function change_database_profile($database = 'default') {
    $connected = ConnectionManager::getDataSource($database);
    if($connected->isConnected()) { 
        return true; 
    }   
    return false;
}
