title: django rest framework queryset doesn't order
body: <p>i use model with <code>Meta</code> <code>ordering = ['-published_date']</code></p>
  
  <p>Now in view:</p>
  
  <pre><code>class InvoiceViewSet(viewsets.ModelViewSet):
      queryset = Invoice.objects.all()
      serializer_class = InvoiceSerializer
      filter_fields = ('table',)
  </code></pre>
  
  <p>And serializer:</p>
  
  <pre><code>class InvoiceSerializer(serializers.ModelSerializer):
      items = ItemSerializer(many=True, allow_add_remove=True)
  
      class Meta:
          model = Invoice
          fields = ('id',  'items', 'table', 'published_date')
  </code></pre>
  
  <p>But this ordering doesn't work, it shows me ordering ASC, and i need DESC, it doesn't affect order at all.</p>
  
  <p>What am i doing wrong?</p>
