Get model in layout?

Question

Yii

Good morning. There are many different models. For users for companies, etc.
There is in layout main.php which is responsible for displaying pages. How can I refer to the company model in this file, for example?
tried like this

<?
$model = new Company();
?>

but when displaying the result, I do not see the fields that should be present there

It is not necessary to access models at the layer level, this is bad practice. It's better to create a widget for this task
Namely fields or data? if fields - then show how you enter, if data - then they can not be, tk. You CREATE a model that has no data by default.
