从django rest框架序列化器中排除一个字段

Question

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

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

Answer 1

BLContainerSerializer在那里创建另一个序列化器说出并排除字段.然后在你的中使用它BLcontainerMergedSerializer.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

Answer 2

有一个字段元属性：

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