Question

我想通过序列化程序对用户输入进行验证，但在验证之后我希望得到带有json类型（str，int，bool，float而不是python实例）的dict，而没有可由用户传递的多余字段。例如：

    serializer = SomeSerializer(data=request.data)
    # request.data = {'a':'abc', 'some_primary_key':33, 'c':'abc'}
    if serializer.is_valid():
        # serializer has fields 'a' and 'some_primary_key' and doesn't have 'c'
        serializer.validated_data == {'a': 'abc', 'some_primary_key': <python instance with pk=33>}

如何在验证后得到类似serializer.plain_validated_data == {'a': 'abc', 'some_primary_key':33}的内容？

An easy way to get it would be to serialize the deserialization's result:

serializer = SomeSerializer(data=request.data)
# request.data = {'a':'abc', 'some_primary_key':33, 'c':'abc'}
if serializer.is_valid():
    # serializer has fields 'a' and 'some_primary_key' and doesn't have 'c'
    output_serializer = SomeSerializer(instance=serializer.validated_data)
    output_serializer.data == {'a': 'abc', 'some_primary_key':33}

通过序列化程序验证数据，而不是获得简单但有效的json
