MY model

class XP(models.Model):

    bizuser = models.ForeignKey(BizUser, on_delete=models.CASCADE)

    current_xp_price = models.IntegerField(default=0)

    xp_created_at = models.DateTimeField(auto_now_add=True)

    xp_updated_at = models.DateTimeField(auto_now_add=True)

i have this function that creates an XP i want if the current user is authenticated(jwttokens) the user can then go ahead to create the XP .when i go to post this data i get to fields that i have to fill that is  current_xp_price and  bizuser which is a  ForeignKey  how do you automatically fill this field (bizuser)ForeignKey rather than having to look for bizuser ID
