You can use the schema_model decorator from marshmallow library in Python to generate dataclasses, field annotation for date of birth, datetime for created and decimal for amount. Here's an example:

from typing import List
import datetime
from marshmallow import Schema, fields, pre_load, post_load, validate
from marshmallow.decorators import pre_dump, post_dump
from marshmallow.fields import Date, DateTime
from marshmallow.validate import validator


@pre_load
def clear(obj):
    obj.date_of_birth = None
    obj.created = None
    obj.amount = None


@pre_dump
def clear(obj):
    obj.date_of_birth = None
    obj.created = None
    obj.amount = None


class OrderSchema(Schema):
    first_name = fields.Str(required=True)
    last_name = fields.Str(required=True)
    date_of_birth = fields.Json(Date())  # Date field marshalled to Date properly using validate decorator
    created = fields.DateTime(phenotypes=[validator(datetime.datetime))]  # DateTime field marshalled to datetime properly using validate decorator
    amount = fields.Decimal()  # Decimal field correctly round-tripped by marshmallow


class OrderSchemaPostloadValidator(BaseModelValidator):
    def __init__(self, *args, **kwargs):
        self.__postload = kwargs[
            'directory'][postload].__postload__
        super().__init__(*args, **kwargs)

    def _process(self, value):
        if not isinstance(value, list):
            value = [value]
        value = build_generic([5000010], value)['reponeliens']
        return value


OrderSchemaPostloadValidationMapping = {
    'firstName': OrderSchemaPostloadValidator('first', 'last')
}

class PreOrderSchema(Schema):
    firstName = fields.Str(required=True)
    lastName = fields.Str(required=True)


class PreOrderSchemaMap(PreOrderSchema):
    amount = fields.Decimal()


class PreOrderSchemaPostLoadValidator(BaseModelValidator):
    def __init__(self, *args, **kwargs):
        self.__postload__preorder = kwargs[
            'directory'][postload]['app'].preorderrelmodel__postload__datacenters
    super().__init__(*args, **kwargs)

    def _process(self, value):
        return [self.__postload__preordernets['first']('datacenters', value)]

    @validates('amount')
    def validate_amount(self, value):
        return self.__general__app...field...validate('', value)


class DateSession(object):
    calendars: List['str']

    def __init__(self, **config: dict) -> None:
        for config in config:
            try:
                defaults[key]
                else:
                    defaults[key]
                    yield
                    defaults[key]
        except KeyError as err:
            msgtext = f'serra is missing a compulsory field: {err}'
            raise structerror({
                keyclass_.DEFAULTS}:
            InvalidFieldError{msgtext})

    def __get__(self, *args...

{
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': datetime.datetime(1977, 3, 16),
'orders': [
Order(amount=100.00, created=datetime.datetime(2024, 2, 7)),
Order(amount=50.00, created=datetime.datetime(1998, 5, 3)),
]
}
def to_dataclass(obj):
def _from_dict(d: dict) -> 'Amount':
if isinstance(d, slice):
d = d[0]
return Amount(
amount=d['amount'],
created=d.get('created') or datetime.datetime.min,
)

def _to_dict(o: object) -> dict:
    return getattr(o, 'data', {
        # Python 3.6 does not support getitem on named tuple attributes yet.
        **{k: v for k, v in sorted(o.__dict__.items(), key=lambda x: isinstance(x[0], (int, float)))},
    })
dataclasses = dataclasses

class Amount:
    __slots__ = ('amt',)

    def __init__(self, amt: float, created: datetime.datetime):
        self.amt = amt
        self.created = created

    @classmethod
    def from_dict(_cls: type, dt?) -> Amount:
        return DataType('_Amount', posted=_dt or datatypes._date)
    @classmethod
    def to_dict(_cls: type) -> 'Amount':
        return {'amount': DataType('_Amount', posted=_dt or datatypes._date)}

class Order:
    __slots__ = ('amt', 'as_str')

    def __init__(self, *args, **kwargs):
        if not kwargs.copy().has_key('created'):
            raise MissingParamError("'created' is requested but not present.")
        kwargs['created'] = to_dataclass(kwargs['created']) # A datetime field whose value is of the wrong type.
        DataClass.__init__(self, *args, **kwargs) # Kicks off the default constructor for a class emitting a new instance with all fields missing values.
    @property
    def as_str(_cls: type = None) -> str or float or NoneType:
        return _from_dict(_cls=AdtUnion[_type])

}

And then

print([to_dataclass(i) for i in in data['orders']]

print({order._data.dict for order in data['orders'] })

)

{{"created": datetime.datetime(2024L, 2L),
"amount": Decimal('100.')}}
{"adf_union": {"amount": Decimal('100.')}}{'adf_union': {"amount": Decimal('199.')}}

You can use the marshmallow-jsonfield library to generate dataclasses for your JSON field.
Here's an example code for that:
```python
from datetime import date
from marshmallow import Schema, fields, pre_load, ValidationError
from dateparser.search import parse
from datetime import datetime as dt
import pytz
import json

Define a schema for the JSON field

class Dated(Schema):
created = fields.Date(required=True)
amount = fields.Decimal(required=True)

Define a schema for the root object

class Order(Schema):
order_id = fields.Int(required=True)
ordered_at = fields.Datetime(required=True)
credit_card_number = fields.String(required=True)

Define the base class for the root object and its fields, and override the to_dict method to include them in the json field serialization as dataclasses

class Root(object):
def init(self, **kwargs):
for key, value in kwargs.items():
setattr(self, key, value)
super().init()

Define the root object and its fields

class RootJSONField(Root):
"""The root object for the root of the schema."""
root = True
date_of_birth = Dated(required=True)
orders = ArrayField(fields=Order(required=True))
def init(self, kwargs):
super().init(kwargs)
self._ordered_at = None
self._credit_card_number = None

Define a deserializer for the root JSON field of an order to include it as a dataclass in its keys of a dictionary (with their values wrapped in dict() if needed). So, e.g., {'orders': [{...}, {'...}, ...], 'date_of_birth': SomeDateObject() } instead of {'orders': [{..., 'date_of_birth': ..., ...}] } which would cause error when you try to access _ordered_at on Incargo because it won't work without date part.

@RootJSONField.register_dataclass()
class OrderDataclassMixin:

def _parse(self, raw):
    self.__root__['_ordered_at'] = parse(raw['orderedAt'], validate='iso8601', strip=False).date()
    self.__root__['ordered_at'] = self.__root__.checked(_parse)
    return self.__root__

Msg represents RaiseError or skip if not valid (or tag first argument with Msg()).

@Field.dataclass() is used to :

• distinguish each field of a schema from each other since Marshmallow usually doesn't have concept of data classes inside any class scope (expecting only tags like @Schema()), but we need dataclasses inside each field scope so we add one more level with "dataclass", indicating that it is really mandatory for required field either we use tag (name) or something else (:name:) right before Required Char(20), Birthday etc... Note: this will always raise error on additional name we pass to required(). But Just like OptionField , we can use @optional() overriding other cases by in precedence with just @if options so that you can use additional keyword using Name() and similars within __isDependsOnScopeConfig() i.e., @optional()(either with Name(), IncludeTag(), JsonPath(), Predicate()) ) too..

from marshmallow import Schema, post, fields, DataType

@dataclass(eq=False)
class ReservedItem:
name: str = None # Don't allow accessing other reserved items by name directly since it is created from auto-prefix of other reserved items since all fields has attribute reservedItem iimitions so except name if you do that outside of this class then you will be getting whole list reservedItems. Libyans are not drunk yet :)
