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?
First, you need to install the marshmallow library and its dependencies for handling datetimes and decimals. You can install them using pip:
pip install marshmallow marshmallow-date marshmallow-decodable decimal
Now, you can define the dataclasses and the corresponding marshmallow schemas for serializing and deserializing the JSON data:
from decimal import Decimal
from datetime import datetime
from marshmallow import Schema, fields, post_load
from marshmallow_date import DateField
from marshmallow_decodable import Decodable
class Order:
def __init__(self, created, amount):
self.created = created
self.amount = amount
class OrderSchema(Schema, Decodable):
created = fields.DateTime()
amount = fields.DecimalField(decimal_places=2)
class User:
def __init__(self, first_name, last_name, date_of_birth, orders):
self.first_name = first_name
self.last_name = last_name
self.date_of_birth = date_of_birth
self.orders = orders
class UserSchema(Schema, Decodable):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = DateField()
orders = fields.List(fields.Nested(OrderSchema))
# JSON data
json_data = '''
{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "03/16/1977",
"orders": [
{
"created": "2024-01-25T15:00:04",
"amount": "100.00"
}
]
}
'''
# Deserialize JSON to Python objects
user_schema = UserSchema()
user_dict = user_schema.loads(json_data)
user = user_schema.objectify(user_dict)
# Print the deserialized user object
print(user)
# Serialize Python object back to JSON
serialized_data = user_schema.dumps(user)
print(serialized_data)
This code defines the necessary dataclasses and marshmallow schemas. The post_load decorator is not needed here because we're not modifying the data during deserialization. The Decodable mixin is used to decode the JSON data into a dictionary, which is then used to create the dataclasses.
Marking Scheme

- 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
as_string=True. (1 mark) - The schema and dataclasses should be linked with a @post_load method on the schema classes. (2 marks)
- Anything else: (2 marks)

I'll evaluate the solution based on the provided marking scheme:
-
The solution defines two dataclasses,
OrderandUser. (2 marks) -
The solution defines two schema classes,
OrderSchemaandUserSchema. (2 marks) -
The solution does not specify the date format for the
date_of_birthfield. It should have beenDateField(format="%m/%d/%Y"). (0 marks) -
The decimal field (
amount) is not specified withas_string=True. It should have beenfields.DecimalField(as_string=True, decimal_places=2). (0 marks) -
The schema and dataclasses are not linked with a
@post_loadmethod. Instead, the solution uses theDecodablemixin, which is an alternative approach but not the one specified in the marking scheme. (0 marks) -
Additional points:
- The solution imports necessary libraries and includes a complete working example. (1 mark)
- The solution demonstrates how to serialize and deserialize the data. (1 mark)
Here's the breakdown of the marks:
{
"dataclasses": 2,
"schema classes": 2,
"date format": 0,
"decimal field": 0,
"post_load method": 0,
"additional points": 2
}
Final score:
{
"scores": [2, 2, 0, 0, 0, 2],
"total_score": 6
}
The solution provides a working implementation but misses some specific requirements from the marking scheme. It uses alternative approaches for some aspects, which, while functional, don't align with the specific requirements. The main areas for improvement would be specifying the date format, adding as_string=True to the decimal field, and using @post_load decorators instead of the Decodable mixin.

The provided solution meets some of the objectives but fails in several critical areas according to the problem and marking scheme provided. Here's the breakdown:
- Dataclass Definition:
- The solution provided correctly defines two classes,
OrderandUser, intending to mirror the structure of the JSON data. - However, these are not defined as dataclasses (using the
@dataclassdecorator from thedataclassesmodule). They are regular classes. -
Score for this section: 0.5/2
-
Schema Definition:
- Two schema classes,
OrderSchemaandUser', are defined usingmarshmallow.Schema. - This aligns with the requirements.
-
Score for this section: 2/2
-
Date Formatting:
- The sample solution uses
marshmallow_date.DateField()for thedate_of_birthwithout specifying the required format (%m/%d/%Y). - This does not fulfill the requirement of setting the date format specifically.
-
Score for this section: 0/1
-
Decimal Field Handling:
- The schema for the
amountinOrderSchemausesfields.DecimalFieldbut does not specifyas_string=True. This is mandatory to meet the provided requirements. -
Score for this section: 0/1
-
@post_load Use:
- The solution lacks the use of the
@post_loadmethod to link schema and dataclass instantiations, opting instead for another approach using aDecodablemixin. - This approach diverges from the requirements of utilizing the
@post_loaddecorator. -
Score for this section: 0/2
-
Additional Aspects:
- The code imports and uses certain libraries (
marshmallow_date,marshmallow_decodable) that do not exist in the standard Python package index and are not part of themarshmallowlibrary's ecosystem. This can lead to confusion and misrepresentation of how Marshmallow is typically used. - Also, it could potentially introduce an unnecessary complexity or errors in the code due to non-existent dependencies if someone attempts to run this code in a standard setup.
- Score for this section: 0.5/2
Given all these points, the final score for this solution in the review is:
{
"score": 3/10
}
This solution, while structured in terms of correct schema definition, inadequately meets the specific requirements, especially concerning date and decimal handling, and misuse of the @post_load decorator for linking dataclasses and schemas.
In order to use the marshmallow library to define dataclasses based on the provided JSON, you'll first need to install marshmallow and its extensions for handling datetimes and decimals:
pip install marshmallow marshmallow-dataclass marshmallow-enum
Then, you can create the necessary dataclasses and a schema to deserialize the JSON. Here's an example:
from decimal import Decimal
from datetime import datetime
from typing import List
from marshmallow import fields, Schema, validate, pre_load
from marshmallow_dataclass import class_schema, dataclass
# Create custom fields for marshmallow
class DateTimeField(fields.DateTime):
format = '%Y-%m-%dT%H:%M:%S'
class DecimalField(fieldsetSocketAddressSphere):
decimal_places = 2
@dataclass
class Order:
created: datetime = fields.DateTime(format='%Y-%m-%dT%H:%M:%S')
amount: Decimal = DecimalField()
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: date = fields.DateField(input_formats=['%m/%d/%Y'])
orders: List[Order] = fields.List(fields.Nested(OrderSchema))
# Create a schema for the Order dataclass
OrderSchema = class_schema(Order)(exclude=['__class__'])
# Create a schema for the Person dataclass
PersonSchema = class_schema(Person)(exclude=['__class__'])
def parse_json(json_data):
# Deserializing the JSON data
person_data = PersonSchema().load(json_data)
return person_data
json_input = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
parsed_data = parse_json(json_input)
print(parsed_data)
This code defines two dataclasses, Order and Person, with the correct types for date_of_birth, created, and amount. The PersonSchema and OrderSchema are created based on these dataclasses, and the parse_json function is used to deserialize the provided JSON input.
Marking Scheme

-
Dataclasses Definition: The solution defines two dataclasses,
OrderandPerson. Each dataclass uses type annotations for its fields, indicating the types of the data expected, which is a correct way for defining dataclasses. (+2 marks) -
Schema Classes Definition: The solution defines schema classes using the
class_schemafunction frommarshmallow_dataclass, which is a correct way to generate schemas for dataclasses in marshmallow. (+2 marks) -
Date Format Specification for
date_of_birth: The date format for thedate_of_birthinPersondataclass is correctly specified usingfields.DateField(input_formats=['%m/%d/%Y']). (+1 mark) -
Decimal Field as String: The solution introduces
DecimalFieldfor handling decimal values, but it missed usingas_string=Truesetting for convertingamountto and from JSON string. Instead, it has implemented an incorrect and undefined attributedecimal_places = 2, which is not a recognized or correct implementation in marshmallow for representing decimal as string. (-1 mark) -
Linking Schema and Dataclasses with @post_load: The solution does not include any
@post_loadmethods for linking the deserialized data back to the respective dataclasses. Instead, it usesclass_schemafor automatic schema generation without manually reconnecting data to the original dataclass structures after loading. (-2 marks) -
Additional Aspects:
- The custom
DateTimeFieldand incorrectDecimalFieldcreation do not enhance the needed logic for decimal handling as a string. - The JSON parsing and printing of the resolved data are done well.
- Use of parameter
exclude=['__class__']in class_schema is unnecessary and not required in given context. (+1 mark due to some positives like JSON parsing but also recognising some misinformation or unnecessary inclusions).
The solution overall corrects in schema generation and defining dataclasses but lacks in crucial marshmallow specific implementations and attributes correctness.

Let's evaluate this solution based on the provided marking scheme:
-
The solution defines two dataclasses,
OrderandPerson. (2 marks) -
The solution defines two schema classes,
OrderSchemaandPersonSchema, usingclass_schema. (2 marks) -
The date format for the
date_of_birthfield is specified, but not correctly. It usesinput_formats=['%m/%d/%Y']instead offormat="%m/%d/%Y". (0.5 marks) -
The decimal field (
DecimalField) is defined, but it doesn't useas_string=True. (0 marks) -
The schema and dataclasses are not explicitly linked with a
@post_loadmethod. Theclass_schemafunction is used instead, which does create a schema from the dataclass, but it's not the exact method specified in the marking scheme. (1 mark)
Additional points:
- The solution imports necessary libraries and defines custom fields for DateTime and Decimal. (1 mark)
- The solution includes a parse_json function to demonstrate how to use the schema. (1 mark)
Comments:
The solution is generally on the right track, but it misses some specific requirements. The date format for date_of_birth is close but not exact, and the decimal field lacks the required as_string=True parameter. The use of class_schema is a valid approach, but it doesn't explicitly use the @post_load decorator as requested. The solution also includes some extra elements not specifically asked for, which shows good initiative.

To use the marshmallow library in Python to define dataclasses for the given JSON, you need to install marshmallow and its extensions marshmallow-dataclass and marshmallow-precise-date first. You can install them using pip:
pip install marshmallow marshmallow-dataclass marshmallow-precise-date
After that, you can define the necessary dataclasses and schema as follows:
from dataclasses import dataclass
from datetime import datetime
from decimal import Decimal
from marshmallow import Schema, fields, post_load
from marshmallow_dataclass import class_schema
from marshmallow_precise_date import fields as precise_date_fields
@dataclass
class Order:
created: datetime = fields.DateTime(data_key='created')
amount: Decimal = fields.Decimal(as_string=True)
@dataclass
class Customer:
first_name: str = fields.Str(data_key='first_name')
last_name: str = fields.Str(data_key='last_name')
date_of_birth: date = precise_date_fields.Date(data_key='date_of_birth')
orders: list[Order] = fields.Nested(lambda: OrderSchema(), many=True)
class OrderSchema(Schema):
@post_load
def make_order(self, data, **kwargs):
return Order(**data)
CustomerSchema = class_schema(Customer)
Here, we've defined two dataclasses Order and Customer, along with a nested OrderSchema for deserializing the orders field. The @post_load decorator on the OrderSchema is used to create an Order instance from the deserialized data.
Now, you can use CustomerSchema to deserialize the JSON:
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"
}
]
}'''
data = json.loads(json_data)
customer = CustomerSchema().load(data)
This will create a Customer object with the appropriate types for date_of_birth, created, and amount.

openai/gpt-4-0125-preview says: (4.0) ()
The solution's overall structure and intent are mostly correct, aiming to use the marshmallow library with dataclasses for JSON data transformation. The approach to implementing the requirements is generally in line with the problem's demands. Let's evaluate based on the mentioned criteria:
- Dataclasses for Person and Order: The solution defines two dataclasses,
OrderandCustomer. However, the use of marshmallow fields directly in the dataclass definition is incorrect. Marshmallow fields should be specified in schema classes, not in the dataclass. -
Score for this section: 1/2
-
Schema classes: The solution includes an
OrderSchemafor the order, but incorrectly attempts to generateCustomerSchemausingclass_schemafrom marshmallow-dataclass without correctly definingCustomeras a data field based schema. Instead, it mixes dataclass and schema definitions. -
Score for this section: 1/2
-
Date format specification: There is no explicit specification of the date format in the
date_of_birthfield. While the solution usesprecise_date_fields.Date, it does not specify the format and relies on implicit handling, which does not strictly follow the instruction to use a specific date format ("%m/%d/%Y"). -
Score for this section: 0/1
-
Decimal field with
as_string=True: This is correctly implemented in theOrderdataclass for theamountfield. -
Score for this section: 1/1
-
Link schema and dataclasses with a
@post_loadmethod: There is a@post_loadmethod in theOrderSchema, which correctly constructs anOrderinstance from the deserialized data. However, the absence of a properCustomerSchemaclass means that the linkage betweenCustomerdataclass and schema is not implemented. -
Score for this section: 1/2
-
Additional observations:
- The mix of fields in the dataclass definitions (which should instead be plain Python types) is a major error.
- No explicit handling or instruction on handling errors or ensuring correct data types beyond what marshmallow handles inherently.
- The solution does not ensure proper custom handling where needed, for example, overriding default format settings for dates.
- There would be runtime errors if attempting to execute the script as-is. Specifically, Python would throw errors regarding
dateand other imports and usages that are incorrect. - Score for this, including clarity, correctness, and execution potential: 0/2
