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 is how you can generate dataclasses from that JSON using marshmallow:
from dataclasses import dataclass
import datetime
from decimal import Decimal
from marshmallow import Schema, fields, post_load
@dataclass
class Order:
created: datetime.datetime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: datetime.date
orders: list[Order]
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(as_string=True)
@post_load
def make_order(self, data, **kwargs):
return Order(**data)
class PersonSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_person(self, data, **kwargs):
return Person(**data)
json_data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{'created': '2024-01-25T15:00:04', 'amount': '100.00'}
]
}
schema = PersonSchema()
person = schema.load(json_data)
print(person)
The key things to note:
- Use the appropriate Marshmallow fields for dates, decimals etc.
- Add post_load methods to the Schemas to construct the dataclasses
- marshmallow will handle the conversion from strings to objects
Let me know if you have any other questions!

The solution is very good overall, addressing most of the requirements effectively. The main issue is the missing date format for the date_of_birth
field, which could lead to parsing errors if the input date format doesn't match the default. Otherwise, the solution demonstrates a good understanding of marshmallow and dataclasses in Python.
openai/gpt-3.5-turbo-0125 says: (None) (0.07¢)
Overall, the solution provided is well-structured and addresses the problem effectively. It correctly defines dataclasses for both the person and order entities, and also provides corresponding schema classes with the necessary field types.
The solution also specifies the date format for the date_of_birth
field, and correctly uses as_string=True
for the decimal field. The linking of dataclasses and schemas through the @post_load
method is appropriately implemented for both the person and order schemas.
Additionally, the solution includes a sample JSON data to demonstrate the usage of the defined schemas to load data into the created dataclasses. This helps in showcasing the practical application of the defined classes.
Overall, the solution covers all the required aspects of the problem and provides a clear and effective approach to using the marshmallow library in Python to generate dataclasses from the given JSON.

Comments on the solution:
- The solution properly defines two dataclasses

date_of_birth

amount
field inOrderSchema
correctly hasas_string=True
, ensuring the Decimal value is serialized as a string (1 mark). - The
@post_load
methods are defined in both schema classes to make sure instances of the corresponding dataclasses are made after loading data (2 marks). - Additional considerations:
- There is no use of the required date format for
date_of_birth
as required by the problem statement. This would not tailor the deserialization process correctly for that specific date string format. The lack of format specification will likely lead to deserialization errors if the default format does not match (0 marks). - Listing type within brackets for orders (
list[Order]
in thePerson
dataclass) is valid in Python 3.9 and later. If backward compatibility is a concern, this might be an issue (1 mark). - It would have been beneficial if default date formats were mentioned as a fallback for when formats are not specified, but this is a minor omission given the explicit requirements (0 marks additional).
- There is no use of the required date format for

Here is how you can generate dataclasses from that JSON using marshmallow:
from dataclasses import dataclass
from decimal import Decimal
from datetime import date, datetime
import marshmallow_dataclass
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class User:
first_name: str
last_name: str
date_of_birth: date
orders: list[Order]
class UserSchema(marshmallow_dataclass.Schema):
date_of_birth = marshmallow.fields.Date()
orders = marshmallow.fields.List(marshmallow.fields.Nested(OrderSchema))
class OrderSchema(marshmallow_dataclass.Schema):
created = marshmallow.fields.DateTime()
amount = marshmallow.fields.Decimal()

schema = UserSchema()
user = schema.load(user_dict)
print(user)
The key things:
- Use @dataclass decorator to generate dataclasses
- Create marshmallow schemas to handle serialization
- Use custom fields like Date, DateTime and Decimal to parse the strings into right types
- Call .load() on the UserSchema to parse the dict into a User dataclass

Comments on the solution:
- The solution correctly defines two dataclasses for User and Order.
- The provided solution does not correctly define the schema classes as per the requirements of using the marshmallow library. Instead, it uses a non-existing
marshmallow_dataclass.Schema
class, which would actually raise an ImportError. - The date format for
date_of_birth
is not specified withformat="%m/%d/%Y"
. - The
Decimal
field in theOrderSchema
should includeas_string=True
argument, which the solution has correctly specified. - The schemas and dataclasses are not properly linked with a
@post_load
method. The solution does not define the@post_load
decorator anywhere in theUserSchema
orOrderSchema
. - The import for the
marshmallow_dataclass
package should either not be there since it is usually not a standard part of the marshmallow package, or a more standard marshmallow import structure should be used. - Additional consideration should have been given to the
OrderSchema
definition within theUserSchema
, which wasn't done correctly.
Final Assessment:
- The solution checks some parts of the problem correctly, such as using data classes and handling the Decimal type. However, it fails to meet all of the specific requirements such as the correct marshmallow schema usage, date formatting, and the proper use of the @post_load
method. Therefore, a score of 5 out of 10 is given, with 5 marks deducted for the unmet requirements.

Comment on the solution:
- The solution provided defines two dataclasses for the person (
User
) and the order (Order
), which earns it two marks. - The solution defines schema class
UserSchema
, but it doesn't correctly create anOrderSchema
, instead, it attempts to define all fields withinUserSchema
. TheOrder
class does not have its own schema, which is incorrect, hence earning 1 mark. - The
date_of_birth
field in the schema does not specify the correct date format (format="%m/%d/%Y"), which results in no marks for this requirement. - The
amount
field does not includeas_string=True
, so it also gets no marks for this point. - The
@post_load
method to link the schema and the dataclasses is missing, resulting in no marks for this criterion. - Under "Anything else," the solution incorrectly uses
marshmallow.fields
without imports and does not appropriately assign fields with proper parameters inUserSchema
. The use ofmarshmallow_dataclass.Schema
is suggested, but no implementation is shown, and it's not the marshmallow way of doing things but rather an additional library that assumes generating schemas from dataclasses (not shown here).
Final score: Out of the 10 possible points, the solution has earned 2 points.
