View Model class in Django

I want to make a view model class in Django whose main purpose is only to display data in templates. like I have an auction model which has the following properties:

class Auction(models.Model):
    seller = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=500)
    description = models.CharField(max_length=4000)
    edit_token = models.CharField(max_length=500)
    starting_price = models.DecimalField(max_length=30, max_digits=19, decimal_places=2)
    bid_price = models.DecimalField(max_length=30, max_digits=19, decimal_places=2, null=True)
    winner_id = models.IntegerField(null=True)
    end_date = models.DateTimeField(blank=True)
    status = models.CharField(max_length=15, choices=STATUS__CHOICES, default='Active')
    revision = models.IntegerField(default=1)

Now I only want to show title, description, starting_price etc to view and main purpose of the view model is I want to change the value of starting_price based on user currency selection so I wanted to add some business logic during the transformation of Database Model class to Template Model class.

Can I use form models or are there any other models I can use?
