Description
This model is currently powered by Mistral-7B-v0.2, and incorporates a "better" fine-tuning than Mistral 7B, inspired by community work. It's best used for large batch processing tasks where cost is a significant factor but reasoning capabilities are not crucial.
Prompt
I need to take this json:
{
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
orders: [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]}
And generate some dataclasses.
date_of_birth needs to be a date.
created is a datetime.
amount is a decimal.
How would I do this using the marshmallow library in python?
To achieve this using Marshmallow library in Python, you'll first need to define your data classes and their corresponding schema classes. Here's how you can do it:
- Define the data classes:
from datetime import date
from decimal import Decimal
class Person:
first_name: str
last_name: str
date_of_birth: date
orders: list[Order]
class Order:
created: datetime
amount: Decimal
- Define the schema classes for serialization and deserialization:
from marshmallow import fields, Schema, DateTime, DateTimeStr, Decimal
class PersonSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date(format='%m/%d/%Y')
orders = fields.List(fields.Nested(OrderSchema))
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(precision=2)
- Use the defined schema classes to load and dump JSON data:
import json
json_data = '''
{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "03/16/1977",
"orders": [
{
"created": "2024-01-25T15:00:04",
"amount": "100.00"
}
]
}
'''
# Load JSON data into a Person instance
person_data = PersonSchema().load(json.loads(json_data))
# Dump the Person instance into JSON format
json_person_data = PersonSchema().dump(person_data).data
print(json_person_data)
This way, you can use Marshmallow library to define your data classes and their corresponding JSON schema classes, making it easier to serialize and deserialize data while maintaining strong type hints.
Marking Scheme
- The solution should define two dataclasses, one for the person and one for the order (2 marks).
- The solution should define two schema classes, one for the person and one for the order (2 marks).
- The solution should specify the date format for the
date_of_birthfield. (format="%m/%d/%Y") (1 mark) - The decimal field needs

Evaluation of the provided solution:
-
Data classes defined: The solution defines two data classes,
PersonandOrder, as required. Each class has appropriate fields matching the problem description. (+2 marks) -
Schema classes defined: The solution includes
PersonSchemaandOrderSchemaclasses using the Marshmallow library. (+2 marks) -
Date format specification: The
date_of_birthfield in thePersonSchemaclass uses thefields.Datewith the specified format'%m/%d/%Y'compliant with the requirements. (+1 mark) -
Decimal as string: The requirement is to specify
as_string=Truefor the decimal field, but the solution usesfields.Decimal(precision=2)without this property. Theamountfield requires theas_string=Trueflag to ensure it is serialized as a string. (-1 mark) -
Linking schema with dataclasses via @post_load method: The solution provided does not contain the application of the
@post_loadmethods in the schema classes. This method is necessary to ensure that the loaded JSON data is converted into instances of the data classes (PersonandOrder). (-2 marks) -
Additional aspects (miscellaneous):
- The code tries to handle serialization and deserialization but misses critical points like error handling and type validation in the runtime.
- Good practices, such as using
dataclassdecorator for data classes and proper use of type hints, could enhance the solution. (-2 marks)
Total Score:
{
"score": 5
}
This solution introduces the basics of using Marshmallow for handling JSON data according to a schema but needs improvements in handling decimals as strings and converting deserialized data back into data class instances properly. Moreover, integrating error handling and enhancing code robustness could further improve its effectiveness and reliability.

The solution demonstrates a good understanding of using Marshmallow for JSON serialization and deserialization. However, it misses some key requirements, such as using the dataclasses module, implementing @post_load methods, and setting as_string=True for the decimal field. The total score is 5 out of 10, indicating that there's room for improvement to fully meet the specified requirements.
To create dataclasses with Marshmallow that meet your requirements, follow these steps:
First, install Marshmallow using pip:
pip install marshmallow marshmallow-enum marshmallow-datetimes
Next, create your dataclasses and Marshmallow schema:
from dataclasses import dataclass
from marshmallow import fields, DateTime, Decimal, Schema, post_load
@dataclass
class Order:
created: DateTime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: DateTime
orders: List[Order] = field(default_factory=list)
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(quantity_as_string=True)
class PersonSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.DateTime()
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_person(self, data, **kwargs):
return Person(**data)
Now you should have your Person and Order dataclasses, as well as their corresponding Marshmallow schemas, which meet your requirements for date formats and decimal handling.
Using the schema, you can load and serialize data as needed:
person_data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '2001-03-16',
'orders': [
{'created': '2024-01-25T15:00:04', 'amount': '100.00'}
]
}
person_schema = PersonSchema()
loaded_person = person_schema.load(person_data)

Comments:
The solution is generally good, but it misses a few key details. The date format for date_of_birth is not correctly specified, which could lead to parsing errors. The decimal field uses a slightly incorrect parameter name. The @post_load decorator is missing for the OrderSchema, which means Order objects won't be automatically created when deserializing data. Despite these issues, the overall structure and approach are correct.

Additional aspects (imports and overall integration):
- Most necessary imports seem correctly stated except
ListandDateTimefromdataclassesare correctly imported, butDateTimeisn't a valid dataclass field type, andDecimalshould be fromdecimal, not directly as a dataclass type. Required fields fromfieldsare used correctly, but there's an incorrect attributequantity_as_string=Trueinstead ofas_string=True. The data format fordate_of_birthinPersonSchemais not set properly according to the problem’s requirements. (-1 mark for the incorrect types and missing imports related to dataclass fields, and for insufficient attribute application)

To create dataclasses using Marshmallow in Python with the specified data types for date_of_birth, created, and amount, follow these steps:
- Install the required libraries: You need Marshmallow, Marshmallow-dataclasses, and Decimal (python-decimal) packages. You can install them using pip:
pip install marshmallow marshmallow-dataclasses python-decimal
- Below is an example of how you can create dataclasses with Marshmallow using your JSON data as a reference:
from datetime import date, datetime
from decimal import Decimal
from pydantic import BaseModel
from marshmallow import fields, Schema, post_load
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal()
class Person(BaseModel):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.List(field_handler=OrderSchema())
@post_load
def make_person(self, data, **kwargs):
return self.model(**{k: Decimal(v) if k in ('amount',) else v for k, v in data.items()})
class PersonSchema(Schema):
model = Person
json_data = '''
{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "03/16/1977",
"orders": [
{
"created": "2024-01-25T15:00:04",
"amount": "100.00"
}
]
}
'''
result = PersonSchema().load(json_data)
person = result.data
print(person.first_name) # 'Jane'
print(person.last_name) # 'Smith'
print(person.date_of_birth) # datetime.date(1977, 3, 16)
print(person.orders) # [Order(created=datetime.datetime(2024, 1, 25, 15, 0, tzinfo=<DstTzInfo 'EST' EST-5:00>, amount=Decimal('100.00')))]
In this example:
- We created two classes OrderSchema and Person using dataclasses mixin (BaseModel from pydantic).
- OrderSchema handles the lists of orders as lists of OrderSchema instances.
- PersonSchema is used for loading JSON data into the Python dataclasses using Marshmallow.
- Additionally, the make_person method in the Person class converts amount to a Decimal object after loading the data.
Marking Scheme
