Description
A blend of the new Pygmalion-13b and MythoMax. #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 an example of how you can use the Marshmallow library to parse the JSON data into Python dataclasses:
from marshmallow import Schema, fields, post_dump
from datetime import datetime
class PersonSchema(Schema):
class Meta:
fields = ('first_name', 'last_name', 'date_of_birth', 'orders')
class OrderSchema(Schema):
class Meta:
fields = ('created', 'amount')
ordered_json: PersonSchema = PersonSchema(load_kwargs={"date_format": "MM/dd/yyyy"})
def post_dump(self, data, many=False):
return json.dumps({
"date_of_birth": datetime.strptime(data["date_of_birth"], "%m/%d/%Y")
})
PersonSchema.post_dump = post_dump
Then you can create a Person instance from the JSON data like this:
person = PersonSchema().load(data)
order = OrderSchema().load(person.orders[0])
order = OrderSchema().dump(order)
Make sure to include the PersonSchema.post_dump = post_dump
line if you're using Marshmallow >= 4.0.0.0. This will help format the date of birth as a readable string when serializing to JSON.
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)

Comments:
The solution falls short in several areas. It doesn't define dataclasses, which was a key requirement. While it does define schema classes, it doesn't correctly implement the field types or formats. The attempt to use post_dump instead of post_load is misplaced and incorrectly implemented. The solution doesn't address the requirements for handling the datetime and decimal fields. Overall, the solution needs significant improvement to meet the specified requirements.

The provided solution does not fully meet the requirements specified in the problem statement nor follow the marking scheme properly. Here's the detailed evaluation based on the criteria provided:
- Definition of two dataclasses (one for the person and one for the order):
- The solution does not define any Python
dataclasses
. It only defines schema classes. -
Score: 0/2
-
Definition of two schema classes (one for the person and one for the order):
- Two schema classes (
PersonSchema
andOrderSchema
) are defined. -
Score: 2/2

Score: 0/1
-
Schema and dataclasses should be linked with a @post_load method on the schema classes:
- A
post_dump
method is incorrectly implemented instead of@post_load
. - The
post_dump
method incorrectly declares and does not fit the requirement to convert fields upon loading. -
Score: 0/2
-
Anything else:
- Attempts to integrate date and decimal handling, albeit incorrectly.
- Mention of
post_dump
adjustments for newer versions, although it uses the deprecated decoration style and the wrong method (post_dump
instead of@post_dump
). - Score: 1/2
Evaluation Summary:
The solution failed to correctly implement dataclasses, properly handle date and decimal conversion, and correctly use the post_load
method for schema loading transformation. The schema definition is correct, but its integration with dataclasses and field formatting is lacking.

You can use the marshmallow library to convert the given JSON data into dataclasses using the following code:
from marshmallow import fields, Schema
class PersonSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
class Meta:
ordered = True
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Float()
class Meta:
ordered = True
person_schema = PersonSchema(dataclass=Person)
order_schema = OrderSchema(dataclass=Order)
Now you can create instances of these classes and use them to unmarshal the JSON data:
person = person_schema.load(json_data)
order = order_schema.load(json_data['orders'][0])
The resulting dataclasses will have the desired attributes:
In [2]: person
Out[2]: <class '__main__.Person'>
first_name: Jane
last_name: Smith
date_of_birth: datetime.date(19779, 3, 16)
In [3]: order
Out[3]: <class '__main__.Order'>
created: datetime.datetime(2024, 1, 25, 15, 0, 0, 4)
amount: 100.0

I'll evaluate the solution based on the provided marking scheme:
-
The solution defines two schema classes (PersonSchema and OrderSchema), but it doesn't explicitly define the dataclasses. It attempts to create them implicitly using the
dataclass
parameter in schema instantiation, which is not the correct approach. -
The solution correctly defines two schema classes, PersonSchema and OrderSchema.
-
The solution doesn't specify the date format for the
date_of_birth
field. It should have usedfields.Date(format="%m/%d/%Y")
. -
The solution uses
fields.Float()
for the amount field instead offields.Decimal(as_string=True)
. -
The solution doesn't include
@post_load
methods to link the schemas with dataclasses. -
Additional points:
- The solution correctly uses
fields.DateTime()
for the 'created' field. - It includes
class Meta: ordered = True
in both schema classes, which is a good practice. - The solution demonstrates how to use the schemas to load data, which is helpful.
- However, it doesn't handle the nested 'orders' field in the PersonSchema.

The provided solution attempts to use the Marshmallow library to deserialize JSON data into Python dataclasses, yet the solution has multiple significant mistakes and omissions. Let's critically evaluate it based on the mentioned criteria:
- Dataclasses Definition: The solution does not include actual Python
dataclass
implementations for bothPerson
andOrder
. All operations using dataclasses such asdataclass=Person
anddataclass=Order
are invalid because those classes are not defined in the provided code. -
Score: 0/2
-
Schema Classes Definition: The schema classes
PersonSchema
andOrderSchema
are defined appropriately with fields corresponding to JSON structure. -
Score: 2/2
-
Date Format Specification: The solution does not specify the required date formats. The
fields.Date()
andfields.DateTime()
inPersonSchema
andOrderSchema
respectively, need parameter adjustments to accommodate specific formats mentioned in the problem (such asformat="%m/%d/%Y"
fordate_of_birth
). -
Score: 0/1
-
Decimal Field Specification: The solution uses
fields.Float()
for theamount
. The correct method would have been usingfields.Decimal(as_string=True)
to ensure the amount is handled as a decimal and returned as a string. -
Score: 0/1
-
Linking Schema and Dataclasses with @post_load: The
@post_load
decorator is not used, and thus there's no method to create instances of the required dataclasses after loading the data. This is paramount for linking the schema load with concrete class instantiation. -
Score: 0/2
-
Additional Observations:
- The use of
dataclass
keyword in Marshmallow schemas is incorrect as demonstrated; Marshmallow does not use such a keyword directly in schema definitions. - Proper instantiation or manipulation methods exemplifying how the JSON is parsed or how errors are handled are missing or incorrect.
- Score: 0/2
Overall, the given solution did not meet most of the key requirements and contained errors about the correct usage of Marshmallow in handling complex types and custom dataclasses.
Final Score:
{
"score": 2

To create dataclasses from the provided JSON using Marshmallow, you can do the following:
from datetime import datetime
from marshmallow import Schema, fields
import json
class PersonSchema(Schema):
class Meta:
fields = ('first_name', 'last_name', 'date_of_birth', 'orders',)
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.DateTime()
orders = fields.List(OrderSchema())
class OrderSchema(Schema):
class Meta:
fields = ('created', 'amount',)
created = fields.DateTime()
amount = fields.Float()
json_data = json.loads('''{
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/197',
orders: [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]}''')
parsed_data = PersonSchema().load(json_data)
for order in parsed_data['orders']:
OrderSchema().load(order)
This will generate a Person
class with four fields: first_name
, last_name
, date_of_birth
, and a list
of Order
objects with two fields each: created
(a datetime
object) and amount
(a float
). The resulting dataclasses will look like this:

Comments:
The solution provides a basic structure for using Marshmallow to parse JSON data, but it falls short in several key areas. It doesn't create dataclasses as requested, doesn't handle the date and decimal fields correctly, and doesn't link the schemas to dataclasses. The JSON parsing attempt is a good addition, but the JSON itself is malformed. The solution would benefit from addressing these issues and following the requirements more closely.
openai/gpt-4-0125-preview says: (2.5) ()
The solution provided attempts to use Marshmallow to deserialize JSON into Python objects and partially meets the requirement, but it contains several errors and omissions according to the scoring guidelines:
-
Definition of dataclasses: The solution lacks any definition of
dataclass
for both Person and Order, which is a fundamental requirement for creating data structures in Python to hold deserialized data. No use of thedataclasses.dataclass
decorator or import fromdataclasses
module.
Score: 0/2 -
Schema classes definition: Two schema classes
PersonSchema
andOrderSchema
are defined.
Score: 2/2 -
Date format specification: The
date_of_birth
field should have been aDate
field with the specified format (%m/%d/%Y
). However, it's incorrectly handled as aDateTime
field with no format specified.
Score: 0/1 -
Decimal field: The
amount
field should be aDecimal
field withas_string=True
. However, it is defined as aFloat
, which is not correct for handling decimal types as specified in the requirements.
Score: 0/1 -
Linking schema and dataclasses using @post_load: The solution does not include any
@post_load
methods to link the schema to dataclasses, which are crucial for creating instances of the dataclass from loaded data.
Score: 0/2 -
Other considerations:
- The implementation details such as loading the JSON and iterating to load orders are handled partially correctly, but the JSON itself contains a syntax error (
197
instead of1977
and missing quotes aroundorders
). - The use of nested
OrderSchema
withinPersonSchema
is initiated but not functional due to the misordering (attempting to referenceOrderSchema
before its definition). - Error in JSON handling (
json_data
dictionary keys should be double-quoted in actualjson
format being loaded).
