从django rest framework serializer中排除一个字段

In the following serializer, I have a nested serializer [ContainerSerializer] field and I want to exclude a field from (container)ContainerSerializer but I don't want any change in ContainerSerializer. How can I do that?

在下面的序列化程序中，我有一个嵌套的序列化程序[ContainerSerializer]字段，我想从（容器）ContainerSerializer中排除一个字段，但我不想在ContainerSerializer中进行任何更改。我怎样才能做到这一点？

class BLcontainerMergedSerializer(serializers.ModelSerializer):
    container = ContainerSerializer()
    class Meta:
        model = BLcontainer

#1

Create another serializer say BLContainerSerializer and exclude fields there. Then use this in your BLcontainerMergedSerializer. Hope this helps.

创建另一个序列化程序说BLContainerSerializer并在那里排除字段。然后在BLcontainerMergedSerializer中使用它。希望这可以帮助。

class BLContainerSerializer(serializers.ModelSerializer):
    class Meta:
        model = Container
        exclude = ('field1', )


class BLcontainerMergedSerializer(serializers.ModelSerializer):
    container = BLContainerSerializer()
    class Meta:
        model = BLcontainer

#2

There is a fields meta property:

有一个字段元属性：

class BLcontainerMergedSerializer(serializers.ModelSerializer):
    container = ContainerSerializer()
    class Meta:
        model = BLcontainer
        fields = ('field1', 'field2')
