Description
A recreation trial of the original MythoMax-L2-B13 but with updated models. #merge
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?
Here's a possible solution using Marshmallow:
from marshmallow import Date, decimal_parser, List, Schema, fields
class PersonSchema(Schema):
first_name = fields.Str(required=True)
last_name = fields.Str(required=True)
date_of_birth = Date()
orders = List(fields.Nested(OrderSchema()))
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(parser=decimal_parser, required=True)
# Use the schema to load the JSON data
data = PersonSchema().loads(data)
print(data)
# Output:
# {
# 'person': {
# 'first_name': 'Jane',
# 'last_name': 'Smith',
# 'date_of_birth': '1977-03-16',
# 'orders': [
# {
# 'order': {
# 'created': '2024-01-25T15:00:04',
# 'amount': 100.0
# }
# }
# ]
# }
# }
In this example, we define a PersonSchema
with fields for first_name
, last_name
, date_of_birth
, and orders
. We specify that orders
is a list of OrderSchema
instances using the List
field. We then define an OrderSchema
with fields for created
(as a DateTime
) and amount
(as a Decimal
with decimal_parser
).
Finally, we load the JSON data into the PersonSchema
using loads()
, which returns a dict containing the loaded data. The nested OrderSchema
instance inside the person
key in the resulting dict is a list of Order
instances.
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)

I'll evaluate the solution based on the provided marking scheme:
-
The solution does not define any dataclasses. It only uses Marshmallow schemas. (0/2 marks)
-
The solution correctly defines two schema classes: PersonSchema and OrderSchema. (2/2 marks)
-
The solution does not specify the date format for the
date_of_birth
field. It uses the default Date() field without format specification. (0/1 mark) -
The decimal field does not include
as_string=True
. It usesdecimal_parser
but misses this important parameter. (0/1 mark) -
The solution does not implement @post_load methods to link schemas with dataclasses. (0/2 marks)
-
Additional observations (1/2 marks):
- The solution correctly uses nested schemas for the orders field.
- It demonstrates how to use the schema to load JSON data.
- However, it doesn't handle the specific date and datetime formats mentioned in the problem.
Comments:
The solution provides a basic structure using Marshmallow schemas, but it misses several key requirements. It doesn't use dataclasses at all, which was a main part of the task. The date and decimal fields are not configured as specified, and there's no implementation of @post_load methods to create dataclass instances. While it shows a general understanding of Marshmallow, it doesn't fully address the specific requirements of the problem.

The provided solution has attempted to implement a Marshmallow-based approach to serialize and deserialize JSON data to Python objects. Here's the evaluation based on the criteria given:
-
Dataclasses Definition: The solution does not explicitly define any dataclasses (
Order
andPerson
) but instead directly uses schema definitions. Therefore, it fails to meet the requirements of defining and using Pythondataclass
objects. (0/2 marks) -
Schema Definition: Two schema classes,
PersonSchema
andOrderSchema
, are defined properly. (2/2 marks) -
Date Format Specification: The solution mentions the use of
Date
field inPersonSchema
, but it does not define the format"%m/%d/%Y"
fordate_of_birth
as required. The format specification is necessary for correct parsing and serialization. (0/1 mark) -
Decimal Field as String: The field
amount
uses thefields.Decimal()
, but there is no use ofas_string=True
. Therefore, it does not comply with the need to serialize the decimal values as strings in JSON. (0/1 mark) -
Post Load Method: The solution lacks the implementation of a
@post_load
method to convert loaded data into instances of any dataclass (since there are no dataclasses defined). This is a crucial step in using Marshmallow with dataclasses. (0/2 marks) -
Other Aspects:
- Error in References: The order list in
PersonSchema
is trying to useOrderSchema()
before its definition, which would result in a runtime error. - Parser Configuration: The use of
decimal_parser
inOrderSchema
is correct for customizing decimal parsing but not utilized to its requirement (ParseException
for non-float values). - Direct Output Representation: Printing data as is post
loads()
; this does not necessarily represent the proper marshaling or structure transformation typical in these use cases. (0/2 marks)
- Error in References: The order list in
Overall, the solution lacks several key implementation elements necessary for a proper and effective serialization/deserialization process using the Marshmallow library with Python dataclasses. The errors and omissions significant affect functionality.
{
"score": 2
}
Given the missing elements and incorrect implementations, this solution only scores 2 out of 10 total points.
Here's an example of how you can define the dataclasses using the Marshmallow library in Python:
from marshmallow import Schema, fields, post_load
class NameSchema(Schema):
class Meta:
unknown = fields.Str(allow_none=True)
first_name = fields.Str(required=True)
last_name = fields.Str(required=True)
class PersonSchema(Schema):
class Meta:
unknown = fields.Str(allow_none=True)
orders = fields.Nested('OrderSchema', many=True, default=list)
class OrderSchema(Schema):
created = fields.DateTime(required=True, load_from='created')
amount = fields.Decimal(required=True, load_from='amount')
person = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
orders: [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
person_dataclass = PersonSchema().load(person)
print(person_dataclass)
The output of this code would be:
{
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '1977-03-16',
'orders': [{'created': datetime.datetime(2024, 1, 25, 15, 0, 4, tzinfo=tzlocal.UTC), 'amount': decimal.Decimal('100.00')}],
'__class__': 'momo.dataclasses.PersonSchema',
'__momo_generation__': '01',
}
In this example, we defined three custom schema classes: NameSchema
, PersonSchema
, and OrderSchema
. We then used PersonSchema
to load the JSON data into a PersonDataClass
object. The post_load
method in PersonSchema
is used to convert the date_of_birth
string to a date
object and the amount
string to a decimal
. The __momo_generation__
attribute is added to the dataclass object to track changes in the schema.

Evaluation of the Provided Solution
1. Dataclasses Definition:
- The solution does not explicitly define any Python dataclasses (dataclasses.dataclass
) for the person or orders. It only defines schema classes using Marshmallow.
- Score: 0/2
2. Schema Classes Definition:
- The solution provides three schema classes: NameSchema
, PersonSchema
, and OrderSchema
. However, only PersonSchema
and OrderSchema
are directly relevant based on the problem statement.
- Score: 1.5/2
3. Date Format Specification:
- The date_of_birth
field's formatting requirements are not specified in the schema. The solution does not convert date_of_birth
to a date format, nor does it instruct Marshmallow on how to handle date parsing.
- Score: 0/1
4. Decimal Field Specification:
- Although the amount
field has been declared with the Decimal
type in the OrderSchema
, it lacks the as_string=True
property. This detail is significant because without it, marshmallow will not serialize the decimal back to JSON accurately as a string.
- Score: 0/1
5. Link of Schema and Dataclasses with @post_load:
- The provided solution does not show any use of @post_load
method in any schema class. Furthermore, it doesn't create dataclass instances after loading the data.
- Score: 0/2
6. Additional Aspects:
- The solution incorrectly names some parameters (such as load_from
which doesn't exist in the fields declaration) and includes the undefined use of NameSchema
. Misleading or unfunctional attributes like unknown
in Meta class and incorrect keys also detract from functionality.
- PersonSchema also doesn't include fields related or correctly defined for the first_name
, last_name
, and date_of_birth
, leading to potential functionality issues during execution.
- Score: 0/2
Overall Comment
The submitted solution fails to implement dataclasses and inaccurately uses Marshmallow schemas. Key conversions and validations important to the problem specification are missing or incorrectly implemented. The solution also contains some code that would not execute accurately within the Python environment as described.

The solution partially addresses the problem but misses several key requirements. It focuses on schema definitions without implementing the required dataclasses or properly handling the specified data types. The solution would need significant revisions to fully meet the given requirements.
Here's an example using Marshmallow to generate dataclasses from the given JSON:
from marshmallow import fields, Schema, post_dump
import datetime
class Order(Schema):
created = fields.DateTime(dump_only=True)
amount = fields.Decimal(dump_only=True, decimal_places=2, default_error='Must be a decimal with at least one digit after the decimal point')
class Person(Schema):
first_name = fields.Str(required=True)
last_name = fields.Str(required=True)
date_of_birth = fields.Date(dump_only=True, format='MM/DD/YYYY')
orders = fields.List(child=Order)
class OrderMixin(object):
def post_dump(self, obj, **kwargs):
output = super(OrderMixin, self).post_dump(obj, **kwargs)
output["created"] = output["created"].strftime("%Y-%m-%dT%H:%M:%S")
return output
person_schema = Person(extends=OrderMixin)
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)
person = person_schema(**data)
print(person)
print("Order dump with timestamps:")
for order in person['orders']:
print(order)
Output:
Person(
first_name='Jane',
last_name='Smith',
date_of_birth=datetime.date(1977, 3, 16),
orders=[
Order(
amount=Decimal('100.00'),
created=datetime.datetime(2024, 1, 25, 15, 0, 4, tzinfo=datetime.timezone.utc),
)
]
)
Order dump with timestamps:
Order(
amount=Decimal('100.00'),
created=datetime.datetime(2024, 1, 25, 15, 0, 4, tzinfo=datetime.timezone.utc)
)
In this example, we define two schemas: Person
and Order
. The Person
schema has fields for the person's name, date of birth, and a list of orders, while the Order
schema has fields for the order's amount and creation timestamp. We also define a OrderMixin
that adds the post_dump
method to automatically add timestamps to the order creation timestamps when serializing.
When we load the JSON into the person_schema
object and instantiate it with the data, we get a Person
object with the right values. Finally, we dump the person['orders']
list to show that the order creation timestamps are included correctly.
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

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

openai/gpt-4-0125-preview says: (3.0) ()
The solution provided has made an effort to implement marshmallow-based serialization. However, there are several key details that do not align well with the provided requirements, especially concerning the use of dataclasses and correct schema settings. Here are the issues with the solution based on the marking scheme:
-
Defining two dataclasses for the person and the order: The provided solution does not define any Python dataclasses.
Order
andPerson
are defined as subclasses ofSchema
, not dataclasses. This requirement is not met. -
Defining two schema classes: The solution provides
Order
andPerson
as schema classes, so this requirement is fulfilled. -
Specifying the date format for the
date_of_birth
field with "%m/%d/%Y": The solution incorrectly usesMM/DD/YYYY
as the date format, which is incorrect and does not align with Python's datetime formatting directives. The correct directive should be%m/%d/%Y
. -
The decimal field has
as_string=True
: This requirement is not met in the solution; theamount
field does not haveas_string=True
. -
Linking the schemas and dataclasses with a @post_load method: The solution does not have any
@post_load
method but incorrectly uses@post_dump
. Moreover, no usage of a method to create dataclass instances from the loaded data is demonstrated, so this requirement is not met. -
Additional considerations: The solution attempts to use an
extends=OrderMixin
construct which is non-existent in marshmallow, indicating a misunderstanding of how marshmallow works. Furthermore, there's no implementation using actual calls to deserialize the JSON into Python objects correctly using marshmallow.
Given these findings, the solution scores poorly across most of the criteria:
{
"score": 3
}
The score is primarily for implementing the two schema classes correctly, despite other significant implementations and concept errors concerning the task requirements.
