First try to ease up CraftCMS Plugin Development with more generic save action

SomePluginController.php

<?php
namespace Craft;

class SomePluginController extends BaseController
{
    // Save Form
    public function actionSaveSomething()
    {
        $this->requirePostRequest();

        $form = craft()->request->getPost();

        if ($id = craft()->request->getPost('someId')) {
            $model = craft()->somePlugin->getSomething($id);
        } else {
            $model = craft()->somePlugin->newSomething();
        }
        
        foreach($model->attributeNames as $attribute){
            $model->$attribute = $form[$attribute];
        }

        // ...
    }
}
