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?
import datetime
import decimal
from marshmallow import Schema, fields
class Order(Schema):
created = fields.Datetime()
amount = fields.Decimal()
class Person(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.List(Order)
person_schema = Person()
person_data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}]
}
person_schema.load(person_data)
print(person_schema.data)
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_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)

The solution does not define any dataclasses. It only defines Schema classes. (0/2 marks)
-
The solution defines two schema classes: Order and Person. (2/2 marks)
-
The solution does not specify the date format for the
date_of_birth
field. (0/1 mark) -
The decimal field is not specified with

. (0/1 mark) -
The solution does not use @post_load method to link schema and dataclasses. (0/2 marks)
-
Additional observations:
- The solution imports necessary libraries.
- It demonstrates how to use the schema to load data.
- However, it incorrectly tries to access
person_schema.data
which is not a valid attribute.
(1/2 marks)
Comments:
The solution provides a basic structure using Marshmallow schemas, but it misses several key requirements. It doesn't use dataclasses, doesn't specify the required date format, doesn't set the decimal field as a string, and doesn't use @post_load to create dataclass instances. The attempt to print person_schema.data
at the end is incorrect; after loading, you would typically access the deserialized data directly from the result of load()
.

The provided solution attempts to use the Marshmallow library to parse and validate JSON data into Python objects. However, there are several essential aspects and errors in the implementation that need to be addressed based on the requirements and marking scheme:
-
Dataclasses Definition: The solution uses
Schema
classes instead ofdataclass
forPerson
andOrder
. This is a major misalignment with the requirement to define two dataclasses (-2 marks). -
Schema Classes Definition: While schema classes have been defined (
Person
,Order
), they are incorrectly implemented asSchema
instead of extending them via proper decorator use or the appropriate linkage with actual data classes (-1 mark). -
Specifying Date Format: The
date_of_birth
field is expected to be specified with the format"%m/%d/%Y"
. This format is notably absent in the definition offields.Date()
(-1 mark). -
Decimal Field Handling: The
amount
should haveas_string=True
to ensure that the decimal field does not lose precision when serialized. This is not specified in thefields.Decimal()
(-1 mark). -
Linking Schema and Dataclasses with @post_load: No
@post_load
method is implemented in either schema class, which is essential for creating actual instances of the defined dataclasses from the parsed data (-2 marks). -
Additional Considerations:
- Error in the serialization: The print statement attempts to access
.data
on the result ofperson_schema.load(person_data)
, which is incorrect usage since loading will return the deserialized data directly. This confusion indicates an error in understanding how Marshmallow handles data handling (-1 mark). - Decimals and datetimes conversion appropriate handling (fields settings) are missing, nothing handled for ensuring encoding/decoding respects the precision and formats required. (-1 mark)
Given the missed requirements and incorrect implementations, the solution does not fully satisfy the problem's demands.

The provided solution seems to attempt to define a serialization/deserialization behavior using the Marshmallow library for a JSON structure provided in the problem. Let's evaluate it based on the given marking scheme:
- Defining Dataclasses: The solution does not define any data classes. The
User
class is defined as a MarshmallowSchema
, not as a Pythondataclass
. The described order structure is also not defined as adataclass
. -
Score: 0/2
-
Defining Schema Classes: The
User
class is defined as a schema correctly, but no separate schema is defined for orders; instead, an attempt is made to define it inline within theUser
schema. -
Score: 1/2
-
Specifying Date Format for
date_of_birth
: Thedate_of_birth
field does not specify the format "%m/%d/%Y" as required. It only states that it is a date field. -
Score: 0/1
-
Decimal Field
as_string=True
: The solution does not specifyas_string=True
for theDecimal
field, which is necessary to maintain it as a string in the output. -
Score: 0/1
-
Using @post_load method to Link Schema and Dataclasses: No
@post_load
methods are used in the provided solution. Moreover, no dataclasses are defined to link with the schemas. -
Score: 0/2
-
Additional Considerations:
- The use of
OrderedDict
in theorders
field is incorrect and not valid syntax in Marshmallow for defining fields within a list. - No correct handling or definition for the
Order
schema or dataclass. - Error in attempt to deserialize data with non-existent
from_dict
method on theUser
schema instance. - Score: 0/2
Overall Evaluation:
- The solution misses key requirements from the problem statement.
- The implementation has several syntax and conceptual errors, such as the misuse of Marshmallow's schema definitions and the lack of required marshmallow features.
- It appears to have significant gaps in understanding both Python dataclasses and the correct usage of the Marshmallow library.

Comments:
The solution partially addresses the problem by defining schema classes using marshmallow. However, it falls short in several key areas:
1. It doesn't use dataclasses as required.
2. It doesn't specify the required date format for date_of_birth
.
3. It doesn't configure the decimal field with as_string=True
.
4. It doesn't use @post_load decorators to link schemas with dataclasses.
To improve, the solution should incorporate dataclasses, add the specified configurations for date and decimal fields, and use @post_load decorators to create instances of the dataclasses from the loaded data.

The provided solution attempts to use the marshmallow
library to parse and validate data, but there are a number of critical issues in relation to the provided problem description and requirements:
-
Dataclasses Definition: The solution does not implement Python dataclasses (
@dataclass
) for encapsulatingUser
andOrder
data. Instead, it defines these entities usingSchema
classes, which are part of the marshmallow library intended for schema definition and not data encapsulation in the form of dataclasses. There was a requirement to define two dataclasses, but it wasn't done (-2 marks). -
Schema Classes Definition: While the solution correctly creates
User
andOrder
as instances ofSchema
, it misuses the purpose of these classes. They should primarily define the structure and validation, yet no specific validation like date formats or decimal precision is set up correctly (-1 mark). -
Date Format Specification: The solution doesn't specify the format for the
date_of_birth
field, which should be handled with the format (%m/%d/%Y
). This is a requirement to correctly parse the string date from JSON into a Python date object. It leaves room for potential errors during date parsing (-1 mark). -
Decimal Field Handling: The
amount
field is marked as aDecimal
type, but it does not specifyas_string=True
which was required to ensure that the decimal value is treated correctly as a string when rendering back to JSON or keeping the precision intact (-1 mark). -
Linking Schema and Dataclasses: The solution does not implement the
@post_load
method, which is necessary for converting loaded data into instances of the defined dataclasses. This step is critical for the proper usage of dataclasses together with schemas in marshmallow (-2 marks). -
Additional considerations: The code does not effectively handle the nesting of orders' data within the user data properly (the fields.List should point to a schema instance, not a class). Additional aspects such as error handling or proper object instantiation for the nested structure are also not covered (-2 marks).
Based on these points, the solution significantly deviates from the requirements, lacking crucial implementations for a correct and functional use of marshmallow with dataclasses in Python.
