access to database from models

[eluser]Unknown[/eluser]
Hi, i have a problem.
I write my class in models/content.php

Code:

class Content extends Model
{
    public function __construct()
    {
        parent::Model();
    }
    
    public function display_content($site)
    {    
        $query = $this->database->query('SELECT name, content FROM content WHERE name="{$site}"');
    }
}

and it shows me an error

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Content::$database

Filename: models/content.php

Line Number: 13
