How to properly get data from Magento model?

Question

PHP

Problem with getting data from the Model (Magento Full Release - ver 1.9.2.4).
I get the model in the actioncontroller:

$news = Mage::getModel('dev_news/news')->getCollection();

Then to get the id I do:

foreach ($news as $item) {
            echo  $item->getId()
        }

Result:

Fatal error: Uncaught Error: Call to a member function order() on null in /home/vitaliy/hosts/module.dev/lib/Varien/Data/Collection/Db.php:506 Stack trace: #0

How to fix it? Can't find an answer.
