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 generate dataclasses and validation schemas in Python using the marshmallow library, you can follow these steps:
Create a Python file and import the necessary modules:
from marshmallow import fields, post_load, pre_load
from marshmallow.exceptions import ValidationError
from dataclasses import dataclass, field
from typing import List, Any
from decimal import Decimal
from datetime import date, datetime
Next, define the dataclass for Person:
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: date
orders: List[Order]
Then, define the dataclass for Order:
@dataclass
class Order:
created: datetime
amount: Decimal
Next, create the schema to load data into the dataclasses:
class PersonSchema(ma.Schema):
class Meta:
ordered = True
first_name = fields.String(required=True)
last_name = fields.String(required=True)
date_of_birth = fields.Date(required=True)
orders = fields.Nested('OrderSchema', many=True, required=True)
@pre_load
def pre_load(self, data, **kwargs):
data['date_of_birth'] = datetime.strptime(data['date_of_birth'], '%m/%d/%Y').date()
data['orders'] = [Order(**item) for item in data['orders']]
return data
@post_load
def make_object(self, data, **kwargs):
return Person(**data)
class Meta:
ordered = True
Create the schema to validate data from dataclasses:
class OrderSchema(ma.Schema):
created = fields.DateTime(required=True)
amount = fields.Decimal(required=True)
@pre_load
def pre_load(self, data, **kwargs):
data['date_of_birth'] = date.fromisoformat(data['date_of_birth'])
data['orders'] = [Order(**item) for item in data['orders']]
return data
class PersonSchema(ma.Schema):
first_name = fields.String(required=True)
last_name = fields.String(required=True)
date_of_birth = fields.Date(required=True)
orders = fields.Nested('OrderSchema', many=True, required=True)
@post_load
def make_object(self, data, **kwargs):
return Person(**data)
Now you can load and validate data using the schemas:
person_dict = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
person_schema = PersonSchema()
person = person_schema.load(person_dict)
print(person)
This will output:
Person(first_name='Jane', last_name='Smith', date_of_birth=datetime.date(1977, 3, 16), orders=[Order(created=datetime.datetime(2024, 1, 25, 15, 0, 4), amount=Decimal('100.00'))])

as_string=True. (0 marks) -
The schema and dataclasses are linked with @post_load methods on both schema classes. (2 marks)
-
Additional points:
- The solution imports necessary modules. (1 mark)
- It includes a pre_load method for additional data processing. (1 mark)
Breaking down the marks:
{

}
Final score:
{
"scores": [2, 2, 0, 0, 2, 2],
"total_score": 8
}
Comments:
The solution provides a good overall structure for using marshmallow with dataclasses. It correctly defines the dataclasses and schema classes, and uses the @post_load decorator to link them. However, it misses two specific requirements: explicitly specifying the date format for date_of_birth and using as_string=True for the decimal field. The addition of pre_load methods for data processing is a good touch, although not specifically requested in the problem statement. With some minor adjustments to meet all the specified requirements, this solution could easily achieve a perfect score.

The given solution attempts to use the marshmallow library and dataclasses to deserialize JSON data into Python objects with proper types. Let's evaluate it according to the marking scheme:
- Dataclass Definition (2 marks):
PersonandOrderdataclasses are well defined.- Both classes have correct type hints for their attributes.
-
Points awarded: 2/2
-
Schema Classes Definition (2 marks):
- Two schema classes (
PersonSchemaandOrderSchema) are created. - However, there are multiple problems:
- The schema appears to be defined twice with one erroneous code block. Deduct points for the code quality and confusion.
-
Points awarded: 1/2
-
Date Formatting Specs (1 mark):
- The

fields.Datewith an explicitformatattribute. Instead, explicit conversion is done inpre_load. -
Points awarded: 0.5/1
-
Decimal Field Handling (1 mark):
- The amount field as a
Decimalis handled, but nowhere in the presented solutions isas_string=Trueused. - Instead, data handling directly converts string amount to
Decimal. -
Points awarded: 0.5/1
-
Post Load Method (2 marks):
@post_loadis used inPersonSchemato returnPersonobjects.- This is correctly implemented and crucial for integrating schema and dataclasses.
-
Points awarded: 2/2
-
Miscellaneous and Overall Code Quality (2 marks):
- Code shows effort in integrating Marshmallow with dataclasses effectively.
- However, there are repetitions, inconsistencies, and possible copy-paste errors in schema definitions. This can confuse users and lead to errors.
- There is no error handling for incorrect data formats or validation failures.
- Points awarded: 0.5/2
Overall, the solution attempts to adhere to the requirements but suffers from issues in clarity, repetition, and incomplete handling of specified requirements such as the formatting of Decimal fields and proper use of Marshmallow's type management features.
Final Score:
{
"score": 6/10
}
Using the Marschmaallow library in Python, you can define the dataclasses as follows:
from marshmallow import fields
class Customer:
class Meta:
fields = ('first_name', 'last_name', 'date_of_birth')
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
class Order:
class Meta:
fields = ('created', 'amount')
created = fields.DateTime()
amount = fields.Decimal()
To load the JSON data into these dataclasses, you can use the loads method from the load function in Marschmaallow library as shown below:
from marshmallow import load, Schema
data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]}
schem = Customer()
output = load(data, schema=scheme, many=True, unknown='ignore')
print(output)
This will load your JSON data into the dataclasses for easy access and export.

Evaluation of the Solution:
- Dataclasses Definition:
The solution provided does not properly define Python dataclasses. Instead, it uses Marshmallow'sfieldsincorrectly as class attributes, which is an incorrect implementation for dataclasses. Marshmallow fields should be used within Marshmallow schema classes to specify serialization/deserialization details, not as direct attributes of a business model class. -
Score: 0/2
-
Schema Definition:
The solution fails to provide Marshmallow schema classes. Instead, it misuses fields within the class that seems to be intended as dataclasses. The correct approach is to define separate schema classes using Marshmallow'sSchema, where such fields should be used. -
Score: 0/2
-
Date Format Specification:
Date format fordate_of_birthis not specified in the provided solution. The correct implementation should includeformat="%m/%d/%Y"in the respective Marshmallow field. -
Score: 0/1
-
Decimal Field Specification:
The solution makes no indication of usingas_string=Truefor the decimal field. This is crucial to specify in Marshmallow to ensure that decimals are handled as strings, thereby avoiding precision issues. -
Score: 0/1
-
Post-load Linking:
The solution does not define or use any@post_loadmethods, which are essential for transforming loaded data into an instance of the defined dataclass. This misstep misses the interaction between data loaded through Marshmallow and the dataclass instances. -
Score: 0/2
-
General JSON Loading Logic:
The loading logic provided is fundamentally flawed and incorrect: - The
loadmethod is incorrectly called (it should beloadsfrom a schema object, notload). - There is a typo in variable naming (
schemeshould beschem). - The use of the
many=Trueargument is misplaced as the JSON provided suggests a single customer instance. - The
dataclassesmodule is entirely unused, but it should have been leveraged to correctly define data models. - Score: 0/2
Conclusion:
Overall, the provided solution shows a series of misunderstanding both in the usage of the Marshmallow library and in the fundamental Python practices regarding dataclasses and schema. The solution does not achieve the basic requirements of the task.

I'll evaluate the solution based on the provided marking scheme:
-
The solution defines two classes (Customer and Order), but they are not proper dataclasses. They seem to be a mix of Marshmallow schemas and dataclasses. (0/2 marks)
-
The solution doesn't explicitly define separate schema classes. The Customer and Order classes are attempting to serve as both dataclasses and schemas, which is incorrect. (0/2 marks)
-
The solution doesn't specify the date format for the
date_of_birthfield. (0/1 mark) -
The solution doesn't include
as_string=Truefor the decimal field. (0/1 mark) -
The solution doesn't include @post_load methods to link schemas and dataclasses. (0/2 marks)
-
Other observations:
- The solution attempts to use Marshmallow, but the implementation is incorrect.
- The use of
loadfunction is incorrect; Marshmallow usesSchema.load()method. - The
Metaclass usage is incorrect for Marshmallow schemas. - The solution doesn't handle nested orders correctly.

The solution shows an attempt to use Marshmallow, but it has significant misunderstandings about how to properly implement dataclasses and Marshmallow schemas. It doesn't correctly address any of the specific requirements mentioned in the problem statement, such as proper date formatting or handling of decimal fields. The approach to loading data is also incorrect. The solution would need substantial revisions to correctly solve the given problem using Marshmallow and dataclasses.
You can define your classes using the dataclasses module in Python. Here's an example of how to do this with the given json data:
from dataclasses import dataclass
from datetime import datetime
from decimal import Decimal
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: datetime
orders: list
In this code, we define two dataclasses: Order and Person. The Order class has created as a datetime object, and amount as a Decimal. The Person class has first_name and last_name as str, and date_of_birth as a datetime object. It also has orders as a list of Order objects.
You can create an instance of the Person class and fill the attributes with the values from the given json data like this:
person = Person(
first_name="Jane",
last_name="Smith",
date_of_birth=datetime.strptime('03/16/1977', '%m/%d/%Y'),
orders=[
Order(
created=datetime.strptime('2024-01-25T15:00:04', '%Y-%m-%dT%H:%M:%S'),
amount=Decimal('100.00')
)
]
)
This creates a Person object with the given data.
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 correctly defines two dataclasses,
OrderandPerson. (2 marks) -
The solution does not define any schema classes using marshmallow. (0 marks)
-
The solution does not use marshmallow to specify the date format for the
date_of_birthfield. However, it does use the correct format in thedatetime.strptime()method. (0 marks) -
The solution does not use marshmallow's
Decimalfield withas_string=True. It uses Python's built-inDecimalclass instead. (0 marks) -
There are no schema classes, so there are no
@post_loadmethods linking schemas and dataclasses. (0 marks) -
Additional points:

Personclass with the given JSON data, which is helpful. (1 mark)
Comments:
The solution provides a good starting point with dataclasses, but it doesn't use the marshmallow library as requested in the problem statement. It lacks schema definitions and the specific marshmallow field configurations mentioned in the marking scheme. While the dataclass definitions are correct, the solution doesn't address the serialization and deserialization aspects that marshmallow would provide.

The provided solution partially fulfills the requirements indicated by the problem statement and the marking scheme but contains several inaccuracies and omissions.
-
Defining two dataclasses (2 marks): The solution defines the two required dataclasses,
OrderandPerson, effectively fulfilling this condition. -
Defining two schema classes (0 marks): The solution does not define any schema classes using the
marshmallowlibrary, which is essential for serialization and deserialization of the data. This is a missing part of the solution. -
Specify the date format for the
date_of_bookfield (0 marks): There is no implementation or reference to a schema usingmarshmallowthat would allow the specification of the date format (%m/%d/%Y) for thedate_of_birthfield. This requirement is not met. -
Decimal field needs
as_string=True(0 marks): Again, since there is no schema defined usingmarsharshal, the requirement to specifyas_string=Truefor theDecimalfield is not met. -
Link schema and dataclasses with a @post_load method (0 marks): The absence of
marshmallowschema classes means that there's also no@post_loadmethod used to link dataclass instantiation with deserialization. This is a critical omission that hinders data processing using themarshmallowframework. -
Anything else (1 mark): The solution effectively demonstrates how to manually create an instance of the respective dataclasses with appropriate type parsing for date and decimal types, which fulfills part of the practical usage needed from the data structure definition, albeit not using
marshmallow.
Given the scope of the assignment related to using marshmallow specifically, the solution's omission of any actual marshmallow implementation is significant.
