Django对象不可重复。如何获取最多查看的对象

你好,我是新手,我有错误,“Zagrania”物体不可测量。我想得到大多数被观看对象并以不同的方式显示它(对象的Wyswietlenia视图)

views.py

def zagrania(request):
zagrania = Zagrania.objects.all().order_by('-data')
najepszezagranie = Zagrania.objects.all().order_by('-wyswietlenia').first()

return render(request, 'zagrania/zagrania.html', { 'zagrania':zagrania, 'najepszezagranie':najepszezagranie})


models.py

class Zagrania(models.Model):
tytul = models.CharField(max_length=70)
data = models.DateTimeField(auto_now_add=True)
autor = models.ForeignKey(User,on_delete=models.CASCADE,default=None)
opis = models.TextField(max_length=276, default='')
wyswietlenia = models.PositiveIntegerField(default=0)
filmik = models.FileField(upload_to="static/filmiki")
#votes= models.IntegerField(default=0)







template

{% for zagranie in najepszezagranie %}

  <a href="{% url 'zagrania_detail' zagranie.id%}">

    <video>
    <source src="{{ zagranie.filmik.url }}" type="video/mp4"></source>
    </video>
  </a>

   <a href="{% url 'zagrania_detail' zagranie.id%}">{{ zagranie.tytul }}</a>


{% endfor %}
