JSONable

✓ from jsonable import JSONable

✗ from jsonable import Type, Base

In 0.2.1, JSONable was renamed to Type and AbstractJSONable to Base, but in 0.3.0 they were reverted. Use JSONable.

Define a class inheriting from JSONable, call to_json() to serialize and from_json() to deserialize.

from jsonable import JSONable class Person(JSONable): def __init__(self, name, age): self.name = name self.age = age p = Person(name="Alice", age=30) json_str = p.to_json() print(json_str) recovered = Person.from_json(json_str) print(recovered.name, recovered.age)

Debug

Known issues

breakingIn v0.3.0, fields with None values or empty dicts are omitted from serialized JSON. This can break code expecting all fields to be present.

fix

Ensure downstream consumers handle missing keys when deserializing.

affects: >=0.3.0

deprecatedThe class names 'Type' and 'Base' used in v0.2.1 are deprecated. Import JSONable directly.

fix

Use 'from jsonable import JSONable'.

affects: >=0.3.0

gotchaJSONable only serializes attributes that are JSON-serializable by default. Custom types require implementing _to_json() and _from_json() methods.

fix

Override _to_json() and add classmethod _from_json() for custom field types.

affects: all

Errors

Common errors & fixes

AttributeError: 'Person' object has no attribute 'to_json'

Using an older version where method name was different, or not inheriting from JSONable.

fix

Ensure you inherit from JSONable and are using version 0.3.1: `from jsonable import JSONable`.

TypeError: Object of type 'Person' is not JSON serializable

Trying to use json.dumps directly on a JSONable instance instead of calling to_json().

fix

Call instance.to_json() which returns a JSON string.

ImportError: cannot import name 'JSONable' from 'jsonable'

Version mismatch; older versions had different class names.

fix

Upgrade to latest version: `pip install --upgrade jsonable`. If using v0.2.1, import Type or Base.
