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 in Python, you can define schemas using the marshmallow's fields
and Schema
classes, and then load the JSON data using those schemas. Here's how you can achieve this for the provided JSON:
from datetime import date, datetime
from decimal import Decimal
from marshmallow import Schema, fields
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(as_string=True)
class UserSchema(Schema):
first_name = fields.String()
last_name = fields.String()
date_of_birth = fields.Date()
orders = fields.Nested(OrderSchema, many=True)
# JSON data
data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
# Load JSON data using the schema
user_schema = UserSchema()
result = user_schema.load(data)
# Access the data as dataclasses
user_data = result.data
orders_data = result.data.orders
print(user_data)
print(orders_data)
In the above code, we create two schemas: OrderSchema
and UserSchema
. OrderSchema
defines the schema for the orders
field, and UserSchema
defines the schema for the overall JSON. The fields in OrderSchema
are defined as DateTime()
and Decimal(as_string=True)
to match the created
and amount
types specified.
We then load the JSON data into dataclasses using the load
method of UserSchema
. The resulting data can be accessed as dataclasses.
Hope this helps!

Comments:
The solution partially addresses the problem by correctly defining schemas and using appropriate field types. However, it falls short in several key areas:
1. It doesn't create actual dataclasses, which was a primary requirement.
2. The date format for date_of_birth
is not specified.
3. There's no use of @post_load to link schemas with dataclasses.
These omissions significantly impact the functionality of the solution. While the schema definitions are correct, the lack of dataclasses means the data isn't being transformed into the required format. The solution provides a good starting point but needs considerable modifications to fully meet the stated requirements.

Evaluation:
- The solution defines schema classes (OrderSchema
and UserSchema
) but does not define actual dataclasses for the order
and user
, so it scores 1 out of 2 for the first criterion.
- Two schema classes are defined, which meets the second criterion, scoring 2 out of 2.
- The date_of_birth
should be specified with a format (%m/%d/%Y
), but the format is not specified in the UserSchema
. Therefore, it scores 0 out of 1 for the third criterion.
- For the amount
field, as_string=True
is correctly used, so it achieves full marks for the fourth criterion (1 out of 1).
- There are no @post_load
methods used in the provided schemas to link them to dataclasses which would produce the instance of a dataclass, so 0 out of 2 marks for the fifth criterion.
- 1 out of 2 marks for additional elements because while the code is functional and correctly loads the JSON data it does not use the marshmallow-dataclass extension for generating dataclasses, neither does it use @post_load
to construct objects from the schema directly, and it does not print the result in the described dataclasses
format (since they're not defined).
- The solution does not handle the point regarding created
being a datetime
as, although it uses DateTime()
, it does not specify the format or if any additional handling is needed.
- Additionally, the last section of the code attempting to access .data
and .orders
from result
would not work as expected since the load
method does not return an object with these attributes. It simply returns the loaded data.
By summing up the scores (1+1+0+1+0+1), the total score for this solution is 4 out of 10.
To generate dataclasses from the given JSON using the marshmallow library in Python, you can do the following steps:
First, you need to install marshmallow library if you do not have it already. You can install it using pip:
pip install marshmallow
Next, you can define the dataclass and schema using marshmallow:
from datetime import date, datetime
from decimal import Decimal
from marshmallow import Schema, fields
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: date
orders: List[Order]
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal()
class PersonSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.Nested(OrderSchema, many=True)
Now, you can use the PersonSchema to deserialize the JSON data and create the dataclass objects:
import json
json_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 = PersonSchema()
person = person_schema.loads(json_data)
print(person)
This will output:
Person(first_name='Jane', last_name='Smith', date_of_birth=datetime.date(1977, 3, 16), orders=[Order(created=datetime.datetime(2024, 1, 25, 15, 0, 4), amount=Decimal('100.00'))])
Now, you have successfully converted the JSON data into dataclass objects using the marshmallow library.

date_of_birth
field using marshmallow's format parameter, which should be specified in thefields.Date()
initialization (0 Marks). - The decimal field for
amount
is declared, butas_string=True

@post_load
methods, which are necessary to link schema deserialization with dataclass instantiation (0 Marks). - The code snippet provided does demonstrate a basic understanding of how to define schemas using marshmallow and how to deserialize JSON data into schema instances, so some points are awarded for that (2 Marks).
The provided solution does not meet most requirements detailed in the marking scheme. This solution needs corrections in how to define dataclasses, adding @post_load
methods, specifying the field types and formats properly, and correctly importing and using required libraries and decorators. The total score reflects these missing and incomplete aspects of the solution.
To generate dataclasses from the given JSON using the marshmallow library in Python, you can create corresponding schemas and load the JSON data using those schemas. Here's an example implementation:
First, you need to install the marshmallow library if it's not already installed:
pip install marshmallow
Then, you can define your dataclasses and corresponding schemas:
from dataclasses import dataclass
from datetime import datetime, date
from decimal import Decimal
from marshmallow import Schema, fields, post_load
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class User:
first_name: str
last_name: str
date_of_birth: date
orders: [Order]
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal()
@post_load
def make_order(self, data, **kwargs):
return Order(**data)
class UserSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.Nested(OrderSchema, many=True)
@post_load
def make_user(self, data, **kwargs):
return User(**data)
Finally, you can load the JSON data into the dataclasses using the defined schemas:
import json
json_data = '''
{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "03/16/1977",
"orders": [
{
"created": "2024-01-25T15:00:04",
"amount": "100.00"
}
]
}
'''
user_schema = UserSchema()
user = user_schema.loads(json_data)
Now, the user
variable will contain the loaded dataclass objects with the appropriate types for date_of_birth
, created
, and amount
.

, fulfilling this requirement fully. - Marks 2: Two schema classes,
OrderSchema
andUserSchema
, are defined, but there's a mistake in thatUser
is used instead ofPerson
, which was expected based on the problem statement. Partial credit given for correctly defining schema classes. - Marks 3: The solution does not specify the date format for the
date_of_birth
field using the format="%m/%d/%Y" as requested in the problem statement, so no marks are granted here. - Marks 4: Although the
Decimal
field is defined correctly in theOrderSchema
, theas_string=True
parameter is missing, so only partial credit is given for adding the correct type. - Marks 5: The
@post_load
methods are correctly implemented in bothOrderSchema
andUserSchema
. Full marks for the correct use of@post_load
. - Marks 6: The fields are missing validation and there is an issue with naming consistency (
User
vs the expectedPerson
), but the rest of the process is correctly implemented, including the de-serialization usingloads
. Partial credit for missing details.
The provided solution results in a total score of 7 out of 10. It effectively creates dataclasses and schema classes with @post_load
methods but misses the specific formatting for the date and the as_string=True
parameter for the decimal amount. Also, there seems to be a minor inconsistency with naming (User
should be Person
as per the problem statement).
