从Django Rest Framework序列化器中排除字段

问题描述

在以下序列化程序中，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，但是我什么都不想要在 ContainerSerializer 中进行更改.我该怎么办?

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?

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

推荐答案

创建另一个序列化器，例如 BLContainerSerializer 并排除其中的字段.然后在 BLcontainerMergedSerializer 中使用它.希望这会有所帮助.

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

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


class BLcontainerMergedSerializer(serializers.ModelSerializer):
    container = BLContainerSerializer()

    class Meta:
        model = BLcontainer
