Как отобразить поле внешнего ключа в Django

# Models

class Vote(models.Model):

    A Class for Votes made by Users for a specific Poller

Я пытаюсь отобразить Vote, сделанные пользователем в его PollerComment, которые связаны через поле ForeignKey. Я пытался применить метод Model в шаблоне, но почему-то он ничего не отображает и не выдает ошибку. Я не уверен, что значительно усложнил простую вещь.

def get_vote(self):
        """
        Get the vote made to the Poller
        of the user who commented
        """
        self.vote_made = ''
        if self.vote.poller_choice_one_vote==True:
            self.vote_made = 'One'
        else:
            self.vote = 'Two'
        return self.vote_made

@register.filter(name='get_vote')
def get_voted(self):
    vote = Vote.objects.get(poller=self.poller, user=self.user)
    return 'One' if vote.poller_choice_one_vote else 'Two'
