django休息框架查询器不排序 [英] django rest framework queryset doesn't order

问题描述

我使用元模型 order = ['-published_date']

现在看来：

class InvoiceViewSet(viewsets.ModelViewSet):
    queryset = Invoice.objects.all()
    serializer_class = InvoiceSerializer
    filter_fields = ('table',)

和序列化器：

And serializer:

class InvoiceSerializer(serializers.ModelSerializer):
    items = ItemSerializer(many=True, allow_add_remove=True)

    class Meta:
        model = Invoice
        fields = ('id',  'items', 'table', 'published_date')

但是这个订单不行，它显示我订购ASC，而我需要DESC，它不影响订单

But this ordering doesn't work, it shows me ordering ASC, and i need DESC, it doesn't affect order at all.

我做错了什么？

推荐答案

解决方案是覆盖 filter_queryset ：

def filter_queryset(self, queryset):
    queryset = super(InvoiceViewSet, self).filter_queryset(queryset)
    return queryset.order_by('-published_date')
