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?
You can achieve this by creating dataclasses using the marshmallow library in python. Here is an example code snippet for creating dataclasses with the specified data types:
from dataclasses import dataclass
from datetime import date, datetime
from decimal import Decimal
from marshmallow import Schema, fields
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class Customer:
first_name: str
last_name: str
date_of_birth: date
orders: list[Order]
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal()
class CustomerSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.Nested(OrderSchema, many=True)
data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
customer_schema = CustomerSchema()
result = customer_schema.load(data)
customer = Customer(**result)
print(customer)
This code snippet defines the dataclasses Order
and Customer
with the specified data types for the fields. It also creates schemas OrderSchema
and CustomerSchema
using the marshmallow library to load the data into the defined dataclasses. Finally, the data from the JSON is loaded into the Customer
dataclass instance and printed out.
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_birth
field. (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)

Specification of Data Format for
date_of_birth
: - The schema does not specify the required format (
"%m/%d/%Y"
) for thedate_of_birth
field. -
Score: 0/1
-
Decimal Field Specification:
- The field
amount

attribute. This attribute ensures that the decimal is loaded/serialized as a string, maintaining exact precision. -
Score: 0/1
-
Linking Schema and Dataclasses using @post_load Method:
- The solution lacks any
@post_load
method in the schema classes, which is necessary to transform loaded data into an instance of the respective data class. -
Score: 0/2
-
Other Aspects:
- The overall example does load JSON and tries to parse it using marshmallow, which partly addresses the task.
- However, it doesn't handle type conversions correctly for decimal and date due to missing specific declarations.
- Score: 1/2 (for attempting to parse and use marshmallow)
Final Score:
{
"score": 5
}
This score reflects the correct setup of data classes and basic schema, but misses essential features for data parsing and conversion specific to the problem's requirements.

Comments:
The solution provides a good starting point by defining the dataclasses and schema classes correctly. However, it misses some important details:
- The date format for
date_of_birth
is not specified, which may lead to parsing errors with the given date format. - The decimal field is not set to use strings, which could cause issues with precision.
- The schemas and dataclasses are not linked using
@post_load
, which means the loaded data won't be automatically converted to dataclass instances.
These issues should be addressed to make the solution more robust and to fully meet the requirements of the problem.

(1 mark)
for understanding the concept of the marshmallow library and how to create Schemas that define fields and how to serialize JSON data to a Python object. However, the sample is missing the actual data conversion within a@post_load
method and it doesn’t ensure proper data types linkage (e.g., date formatting) between the marshmallow fields and the dataclasses.
The resulting score, based on the above criteria, is 3
out of 10
.
You can achieve this by defining the dataclasses using the marshmallow
library in Python. Here is an example code snippet that demonstrates how to achieve this:
from dataclasses import dataclass
from datetime import datetime, date
from decimal import Decimal
from marshmallow import Schema, fields
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class Customer:
first_name: str
last_name: str
date_of_birth: date
orders: Order
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(as_string=True)
class CustomerSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.Nested(OrderSchema)
# Load the JSON data
data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
# Deserialize the JSON data using the schema
customer_schema = CustomerSchema()
customer_data = customer_schema.load(data)
# Print the deserialized data
print(customer_data)
In this code snippet, we define the Order
dataclass to represent the order data, and the Customer
dataclass to represent the customer data. We then define schema classes OrderSchema
and CustomerSchema
that map to the corresponding dataclasses. We use the fields.DateTime()
, fields.Decimal(as_string=True)
, and fields.Date()
to specify the data types for the fields in the schema.
Finally, we load the JSON data using the CustomerSchema
and print the deserialized data.

Comments:
The solution provides a good foundation for using marshmallow with dataclasses. However, it misses a few key points:
- The date format for
date_of_birth
is not specified, which is necessary for proper parsing of the input string. - The schema classes are not linked to the dataclasses using
@post_load
decorators, which means the deserialized data will be dictionaries rather than dataclass instances. - The
orders
field in theCustomer
dataclass is defined as a singleOrder
, but in the schema and sample data, it's a list of orders.
These issues should be addressed to fully meet the requirements and to ensure the deserialized data is in the correct format.

Decimal Field Handling: The solution correctly specifies
as_string=True
for the decimal field, ensuring correct serialization of theamount
field. -

@post_load Method: There is no
@post_load
method defined in either of the schema classes to link the schema deserialization directly to dataclass instantiation. The schema directly deserializes the data into a dictionary structure instead. -
Score: 0 marks
-
Other considerations:
- The solution correctly uses fields such as
fields.DateTime()
andfields.Decimal(as_string=True)
to match the respective types. - Error handling, validation, or explanation of the deserialization errors and their resolutions is not considered or addressed.
- Score: 0.5 marks for matching field types but not addressing other details or enhancements such as nested handling or advanced marshmallow features.

Comments on the solution:
- The solution correctly defines two dataclasses for the
Order
andCustomer
, fulfilling the requirements for the first item in the marking scheme. - Two schema classes,
OrderSchema
andCustomerSchema
, are also correctly defined, fulfilling the second item in the marking scheme. - However, the solution does not specify the date format for the
date_of_birth
field using the format"%m/%d/%Y"
as required, thus missing marks for the third item. - The solution correctly uses
as_string=True
for the decimal field, fulfilling the fourth item in the marking scheme. - The solution fails to link the schemas and dataclasses with a
@post_load
method. This step is crucial to return an instance of the dataclass when loading the JSON data. Therefore, no marks are given for the fifth and the "anything else" items in the marking scheme.
The total score, therefore, is 5 out of 10, as detailed in the score breakdown.
To achieve this using the marshmallow library in Python, you can create dataclasses for the JSON data and use marshmallow schema to define the data structure and data types. Here's an example code snippet to demonstrate this:
from dataclasses import dataclass
from datetime import date, datetime
from decimal import Decimal
from marshmallow import Schema, fields, validate
# Define dataclass for orders
@dataclass
class Order:
created: datetime
amount: Decimal
# Define dataclass for user
@dataclass
class User:
first_name: str
last_name: str
date_of_birth: date
orders: [Order]
# Define schema for Order dataclass
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(places=2)
# Define schema for User dataclass
class UserSchema(Schema):
first_name = fields.String()
last_name = fields.String()
date_of_birth = fields.Date()
orders = fields.Nested(OrderSchema, many=True)
# Load JSON data
data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '1977-03-16',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
# Initialize UserSchema
user_schema = UserSchema()
# Deserialize JSON data to User dataclass object
user_object = user_schema.load(data)
# Print User dataclass object
print(user_object)
In this code snippet, we first define the dataclasses for Order and User, where Order contains information about the order, and User contains information about the user along with a list of orders. We then define schemas for Order and User using marshmallow, specifying the data types for each attribute.
We load the JSON data into the UserSchema and use the load
method to deserialize the JSON data into a User dataclass object. Finally, we print the User dataclass object to verify the deserialization process.
Make sure to have the marshmallow library installed in your Python environment by running pip install marshmallow
.

- The schema classes for both the person (User
) and the order (Order
) have been defined, but they do not use the correct formats for date_of_birth
, created
, and amount
fields (-4 marks).
- The amount
field is missing the as_string=True
attribute, which is required to ensure that the decimal is treated as a string and not a float (-1 marks).
- The date format for the date_of_birth
field is not specified (format should be "%m/%d/%Y") (-1 marks).
- While the solution does create dataclasses and schema classes, and attempts to deserialize JSON data, it incorrectly assumes the date format in the JSON (format should be "%m/%d/%Y" for the date_of_birth
field and should deserialize the created
field as a datetime object) and does not implement appropriate formats or post-load transformations (-2 marks).
Given the marking scheme and the mistakes present in the solution provided, I awarded 1 point for correctly creating dataclasses and schema classes (even though they are incomplete and lack integration) under "Anything else", which captures some intrinsic value of the code written.
The total score awarded is 1 out of 10.
