python - DRF : How to hide the password in serializers that use the depth option?

Question

我正在为 User 使用以下序列化程序模型，但是当我使用深度处理外键时，密码显示在 User 中目的。
用户序列化器:

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        read_only_fields = ('is_active', 'is_staff', 'is_superuser',)
        exclude = ('password', )
        extra_kwargs = {'password': {'write_only': True, 'min_length': 4}}

在下面的序列化程序中一切都很好:

class AuditSerializer(serializers.ModelSerializer):
    def __init__(self, instance=None, **kwargs):
        if instance:
            setattr(self.Meta, 'depth', 10)
        else:
            setattr(self.Meta, 'depth', 0)
        super(AuditSerializer, self).__init__(instance, **kwargs)

    initiator = UserSerializer(read_only=True)

    class Meta:
        model = Audit
        fields = ['id', 'initiator']
        read_only_fields = ['id', 'initiator']
        depth = 0

但是在下面与以前的模型/序列化程序有关的内容中，我遇到了密码问题:

class AuditAttachmentSerializer(serializers.ModelSerializer):
    def __init__(self, instance=None, **kwargs):
        if instance:
            setattr(self.Meta, 'depth', 10)
        else:
            setattr(self.Meta, 'depth', 0)
        super(AuditAttachmentSerializer, self).__init__(instance, **kwargs)

    class Meta:
        model = AuditAttachment
        fields = ['id', 'audit']
        read_only_fields = ['id']
        depth = 0

Answer 1

我删除了__init__方法并将其更改为以下解决方案。
