django - 如何过滤一组值的字段

Question

我有一个名为products的模型。该类别属于该模型。现在我可以用一个值过滤这个部分字段。其实我想为同一个字段按多个值过滤

示例：如果我用电话过滤（是一个类别）它可以工作但是对于这个部分字段，我需要按电话和案例过滤

筛选

class ProductFilter(filters.FilterSet):
    min_price = filters.NumberFilter(field_name="price", lookup_expr='gte')
    max_price = filters.NumberFilter(field_name="price", lookup_expr='lte')

    class Meta:
        model = Product
        fields = ['category',
                  'min_price', 'max_price'
                  ]

看法

class ProductListView(generics.ListAPIView):
    permission_classes = [IsAuthenticated]
    queryset = Product.objects.all()
    serializer_class = ProductListSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filter_class = ProductFilter

我怎么做？有人能帮我吗？

定义 aCharFilter并指定lookup_expr参数，

class ProductFilter(filters.FilterSet):
    min_price = filters.NumberFilter(field_name="price", lookup_expr='gte')
    max_price = filters.NumberFilter(field_name="price", lookup_expr='lte')
    category = filters.CharFilter(lookup_expr='in')

    class Meta:
        model = Product
        fields = ['category', 'min_price', 'max_price']
