问题 I want a Marshmallow Schema with the following output json - { "_id": "aae216334c3611e78a3e06148752fd79", "_time": 20.79606056213379, "more_data" : {...} } Marshmallow doesn't serialize private members so this is as close as I can get - class ApiSchema(Schema): class Meta: strict = True time = fields.Number() id = fields.String() But I do need the underscores in the output json.
