How to do validation in django?

Question

Django

Let's say we display products from the database, some products have is_sale=True, others have False. How to check True or False when outputting to html, or does it need to be done by views? If in PHP such a function is approximately implemented through

if($is_sale == True){
 <div>Sale</div>
}

Is it possible to do this in django?
