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 using the marshmallow library, we first need to install it.
Open your terminal and run the following command to install marshmallow:
pip install marshmallow
Once it's installed, you can create two separate schemas for the JSON file and the dataclasses. Each schema will define the structure of the object and the type of each field, specifying how to serialize it.
Here's an example for your JSON:
from marshmallow import Schema, datetime, fields
from marshmallow.utils import datetime as marshmallow_datetime
# Creating the schema for the JSON
class PersonSchema(Schema):
class Meta:
fields = ('first_name', 'last_name', 'date_date_date_of_birth', 'orders')
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date(default=marshmallow_datetime(utc=True))
orders = OrderSchema(many=True)
# Creating the schema for Orders
class OrderSchema(Schema):
class Meta:
fields = ('created', 'amount')
created = fields.DateTime(default=marshmallow_datetime(utc=True)) )
Now to generate the dataclasses, run the following code:
from marshmallow_dataclass import dataclass, DataclassSchema, fields
from datetime import datetime as python_datetime
from decimal import Decimal
# Creating the person dataclass
@dataclass(frozen=True)
class Person:
first_name: str
last_name: str
date_of_birth: datetime
orders: list[Order]
# Creating the order dataclass
@dataclass(frozen=True)
class Order:
created: datetime
amount: Decimal
# Creating dataclass schemas
class PersonDataclassSchema(DataclassSchema):
class Meta:
dataclass = Person
__fields__ = ('first_name', 'last_name', '_date_of_birth', 'orders')
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date(default=(python_datetime.utcfromtimestamp(0)))
orders = OrderDataclassSchema(many=True)
class OrderDataclassSchema(DataclassSchema):
class Meta:
dataclass = Order
__fields__ = ('created', 'amount')
created = fields.DateTime(default=(marshmallow_datetime(
utc=True).astimezone(python_datetime.utcfromtimestamp(
0))))
amount = fields.Decimal(precision=2, append=True)
At this point, you can use the classes/schemas to load and dump objects. For example:
# Loading JSON into classes
json_data = {... your JSON ...}
person_data_cl = PersonDataclassSchema(dump=json_data).load().data
# Dumping data back into JSON
json.dump(person_data_cl.__marshmallow_dataclass2dict__(), open('jsonfile.json', 'w'), indent=2)
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)

Let's evaluate this solution based on the provided marking scheme:
-
The solution defines two dataclasses, Person and Order. (2 marks)
-
The solution defines two schema classes, PersonSchema and OrderSchema. It also defines two additional schema classes, PersonDataclassSchema and OrderDataclassSchema. (2 marks)
-
The solution does not specify the date format for the
date_of_birth
field as required (format="%m/%d/%Y"). (0 marks) -
The decimal field (amount) is not specified with
as_string=True
. Instead, it usesprecision=2, append=True
. (0 marks) -
The solution does not explicitly use @post_load method to link schemas and dataclasses. Instead, it uses marshmallow_dataclass to generate schemas from dataclasses. (1 mark)
-
Additional points:
- The solution uses marshmallow_dataclass, which is a good approach for generating dataclasses and schemas together.
- It handles UTC timestamps for datetime fields.
- It demonstrates how to load JSON data into classes and dump data back to JSON.

The solution demonstrates a good understanding of using marshmallow with dataclasses, but misses some specific requirements like date format and decimal field specification. It also uses a different approach for linking schemas and dataclasses than what was explicitly asked for. Overall, it's a functional solution but doesn't fully meet all the specified criteria.
openai/gpt-4-0125-preview says: (3.0) ()
The solution attempts to address the problem of using dataclasses and marshmallow together for JSON serialization/deserialization for specified fields of specific formats. However, there are significant issues in the approach and implementation.
-
Two dataclasses definition (Person and Order) - The code defines both required dataclasses (
Person
andOrder
). These classes are set correctly to manage the object structures given in the JSON.
Score: 2/2 -
Two schema classes definition - The schema classes (
PersonSchema
andOrderSchema
) are not aligned properly between the simpleSchema
andDataclassSchema
classes. The solution mixes these two approaches which complicates understanding and practical usage. Furthermore, there are errors and inconsistencies in field handling.
Score: 1/2 -
Date format specification for
date_of_birth
field - The format fordate_of_birth
(%m/%d/%Y
) is not specified in the solution. NeitherPersonSchema
norPersonDataclassSchema
explicitly handles the date format as required.
Score: 0/1 -
Decimal field with
as_string=True
- Theamount
field inOrderDataclassSchema
should be aDecimal
and explicitly specify serialization as a string. This is not correctly implemented in the provided solution.
Score: 0/1 -
Linking schemas and dataclasses with
@post_load
method - The provided solution does not include any@post_load
methods which is a crucial step for marshmallow to construct the dataclass instances from loaded data. There's no connection depicted between schema loading and dataclass instantiation.
Score: 0/2 -
Additional elements - The overall code is hard to follow due to a mix of incorrect and incomplete example implementations. Documentation or examples of loading and dumping data as per the problem statement (e.g., correctly loading from JSON data to dataclasses or vice versa) are either incorrect or incomplete. Numerous syntax errors and misused library functionalities are present. This significantly hinders usability.
Score: 0/2
Overall, the solution shows a fundamental misunderstanding or misapplication of the marshmallow library and dataclasses, especially with respect to schema linking and field type handling.
Final score:
{
"score": 3
}
You can use Marshmallow's AutoField
and DateTimeField
along with DecimalField
to create your required dataclasses. Here's how you can do it:
from marshmshmallow import AutoField, DateTimeField, DecimalField
from marshmallow import fields, Schema
class OrderSchema(Schema):
created = DateTimeField()
amount = DecimalField(positive=True)
class UserSchema(Schema):
first_name = AutoField()
last_name = AutoField()
date_of_birth = DateTimeField() # since you're storing dates in ISO format, Marshmallow can convert it
orders = fields.Nested('OrderSchema', many=True)
Then, you can load the JSON using the load()
method and convert it into the User
dataclass.
from marshmallow import ValidationError
json_data = '''
{
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '1977-03-16',
'orders': [
{
'created': '2024-01-25T15:00:044',
'amount': '100.00'
}
]
}
'''
user_schema = UserSchema()
try:
data = user_schema.load(json.loads(json_data))
except ValidationError as err:
print(err)
else:
print(data)
This code will load the JSON data and validate it using the defined schemas. Then it will convert the data into the appropriate dataclasses. Note that the date format has been adjusted in the provided JSON to match the format Marshmallow expects for dates (YYYY-MM-DD). Also, the time part in the created field has been corrected in the provided JSON.

Comments:
The solution provides a good starting point with the correct use of Marshmallow schemas. However, it misses several key requirements:
- It doesn't create dataclasses as requested.
- The date format for date_of_birth
is not correctly specified.
- The DecimalField is missing the as_string=True
parameter.
- There are no @post_load methods to create dataclass instances.
- The JSON example in the solution differs from the one in the problem statement, which could lead to confusion.

The provided solution has several issues and missed portions according to the specified problem statement and marking scheme:
- Definition of two dataclasses: The solution misses defining any dataclasses, instead it directly defines schema classes. Dataclasses have specific characteristics and need to be defined using Python's
dataclasses.dataclass
decorator. - Definition of two schema classes: Two schema classes are indeed defined (
OrderSchema
,UserSchema
), which correctly matches this criterion. - Specification of the date format for
date_of_birth
: It incorrectly usesDateTimeField
fordate_of_birth
without specifying the required date format. The format needed was"%m/%d/%Y"
but was omitted. - The
DecimalField
needsas_string=True
: WhileDecimalField
was used inOrderSchema
, theas_string=True
argument was omitted, which leads to inaccurate adherence to the problem’s requirements. - Linking schema and dataclasses with
@post_load
: This is completely omitted from the solution. There are no@post_load
methods to create instances of dataclasses after loading the data. - Error handling completeness: While the error handling using
try-except
is correct, and there's a basic loading mechanism, the JSON string provided injson_data
has invalid Python strings (using single quotes instead of double quotes, which JSON requires).
These issues severely impact the ability to solve the problem as outlined. The main use of marshmallow's transformation capabilities from JSON to custom Python objects through proper schema definition and data loading was not fully realized, particularly with the specific requirements for data types and formats.
{
"score": 3
}
Points are given for defining the schema classes correctly and for handling JSON loading, despite missing the critical requirements for the data types and a complete functioning solution.
First, you'll need to install the marshmallow
library using pip:
pip install marshmallow
Next, you can create a CustomerSchema
and OrderSchema
using the marshmallow
library to define the structure of your JSON data. Here's an example of how to do that:
from marshmallow import Schema, fields, datetime, pre_dump
from decimal import Decimal
class DateOfBirth(fields.Field):
def _serialize(self, value, attr, obj):
return value.strftime('%Y-%m-%d')
def _deserialize(self, value, attr, data):
return dates.fromisoformat(value)
class Created(fields.Field):
def _serialize(self, value, attr, obj):
return value.strftime('%Y-%m-%dT%H:%M:%S')
def _deserialize(self, value, attr, data):
return datetime.fromisoformat(value)
class Amount(fields.Field):
def _serialize(self, value, attr, obj):
return str(value)
def _deserialize(self, value, attr, data):
return Decimal(value)
class OrderSchema(Schema):
created = Created()
amount = Amount()
class CustomerSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = DateOfBirth()
orders = fields.Nested(OrderSchema, many=True)
Now, you can load your JSON data into a Customer
object and dump it back into JSON using the CustomerSchema
:
from datetime import dates
json_data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
customer_schema = CustomerSchema()
customer = customer_schema.load(json_data)
print(customer_schema.dump(customer))
This will output the JSON representation of your Customer
object with the appropriate data types:
{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "1977-03-16",
"orders": [
{
"created": "2024-01-25T00:00:00",
"amount": "100.00"
}
]
}

Evaluation of the Provided Solution
- Dataclasses Definition:
- The solution failed to define any dataclasses. It only uses
marshmallow.Schema
to validate and handle serialization and deserialization but not the related dataclasses. -
Score: 0/2
-
Schema Classes Definition:
- Correctly defined two Schema classes:
OrderSchema
andCustomerSchema
. -
Score: 2/2
-
Date Format Specification:
- The solution correctly created custom fields but failed to implement the right date format specification (
%m/%d/%Y
) fordate_of_birth
. Instead, it used ISO formatting for serialization and deserialization. -
Score: 0/1
-
Decimal Field as String:
- The
Amount
custom field converts the decimal to string appropriately for serialization but overlooked theas_string=True
property that signals the intent clearly in schema definitions for future code maintainers. -
Score: 0.5/1
-
Post-Load Linking:
- The solution includes no
@post_load
methods to link schema validation results directly to a dataclass instance, which is essential for proper separation of data representation and serialization logic. -
Score: 0/2
-
Other Considerations:
- Although the custom fields for handling date, datetime, and decimals are provided, the
DateOfBirth
class attempted to usedates.fromisoformat(value)
which is incorrect (proper method should bedatetime.date.fromisoformat(value)
underdatetime.date
). Incorrect use of imports and methods might cause runtime errors. - The code comments, clarity, and adherence to requirements like handling of the nested schema are reasonably good. However, this section suffers from functionality gaps as noted.
- Score: 0.5/2
Overall Evaluation: The solution provides a basic structure for serialization and deserialization using Marshmallow but misses critical marks in terms of correct implementation and integration of date and decimal handling according to specifications. Additionally, it fails to make use of Python's object orientation effectively by omitting proper dataclasses that work tightly with the schemas, which would be core to properly managing structured data in applications.

The solution does not define dataclasses for the person and order. (0/2 marks)
-
The solution defines two schema classes: CustomerSchema and OrderSchema. (2/2 marks)
-
The solution does not specify the correct date format for the

Additional points:
- Custom field classes are created for date_of_birth, created, and amount. (1/2 marks)
- The solution demonstrates how to use the schema to load and dump data. (1/2 marks)
Comments:
The solution partially addresses the requirements but misses some key points. It correctly defines schema classes and handles the amount as a string. However, it doesn't use dataclasses, doesn't specify the correct date format for date_of_birth, and doesn't use @post_load to create objects. The custom field classes are a good approach but could be simplified using built-in marshmallow fields with appropriate arguments.
