Bases: marshmallow.Schema

Base schema class with which to define custom schemas.

Example usage:

import datetime as dt
from dataclasses import dataclass

from marshmallow import Schema, fields


@dataclass
class Album:
    title: str
    release_date: dt.date


class AlbumSchema(Schema):
    title = fields.Str()
    release_date = fields.Date()


album = Album("Beggars Banquet", dt.date(1968, 12, 6))
schema = AlbumSchema()
data = schema.dump(album)
data  # {'release_date': '1968-12-06', 'title': 'Beggars Banquet'}

Parameters

only – Whitelist of the declared fields to select when instantiating the Schema. If None, all fields are used. Nested fields can be represented with dot delimiters.
exclude – Blacklist of the declared fields to exclude when instantiating the Schema. If a field appears in both only and exclude, it is not used. Nested fields can be represented with dot delimiters.
many – Should be set to True if obj is a collection so that the object will be serialized to a list.
context – Optional context passed to fields.Method and fields.Function fields.
load_only – Fields to skip during serialization (write-only fields)
dump_only – Fields to skip during deserialization (read-only fields)
partial – Whether to ignore missing fields and not require any fields declared. Propagates down to Nested fields as well. If its value is an iterable, only missing fields listed in that iterable will be ignored. Use dot delimiters to specify nested fields.
unknown – Whether to exclude, include, or raise an error for unknown fields in the data. Use EXCLUDE, INCLUDE or RAISE.

Changed in version 3.0.0: prefix parameter removed.

Changed in version 2.0.0: __validators__, __preprocessors__, and __data_handlers__ are removed in favor of marshmallow.decorators.validates_schema, marshmallow.decorators.pre_load and marshmallow.decorators.post_dump. __accessor__ and __error_handler__ are deprecated. Implement the handle_error and get_attribute methods instead.

Bases: marshmallow.Schema

Messages from callback writers and loggers in stan::callbacks.

NOTE: You SHOULD NOT use this schema. This schema exists for testing and for documentation. It SHOULD NOT be used to process a large number of JSON messages. Doing so will slow down any program.

This schema is intended for messages emitted by C++ classes which inherit from

stan/callbacks/writer.hpp, and
stan/callbacks/logger.hpp.

In particular, the schema matches a JSON-based “version” of the CSV-focused stan/callbacks/stream_writer.hpp and stan/callbacks/stream_logger.hpp.

This version is found “inside” the httpstan-specific httpstan/socket_writer.hpp and httpstan/socket_logger.hpp.

WriterMessage is a data format for all messages written by the callback writers defined in stan::callbacks. These writers are used by the functions defined in stan::services. For example, stan::services::sample::hmc_nuts_diag_e uses one logger and three writers:

logger Logger for informational and error messages
init_writer Writer callback for unconstrained inits
sample_writer Writer for draws
diagnostic_writer Writer for diagnostic information

WriterMessage is a format which is flexible enough to accommodate these different uses while still providing a predictable structure.

A WriterMessage has a field topic which provides information about what the WriterMessage concerns or what produced it. For example, the topic associated with a WriterMessage written by sample_writer in the function is sample.

The “content” of a message is stored in the field values. This is either a list or a mapping.
