v.2.1.0

StateMachine 2.1.0

June 11, 2023

What's new in 2.1.0

Added support for declaring states using Enum

Given an Enum type that declares our expected states:

>>> from enum import Enum

>>> class Status(Enum):
...     pending = 1
...     completed = 2

A StateMachine can be declared as follows:

>>> from statemachine import StateMachine
>>> from statemachine.states import States

>>> class ApprovalMachine(StateMachine):
...
...     _ = States.from_enum(Status, initial=Status.pending, final=Status.completed)
...
...     finish = _.pending.to(_.completed)
...
...     def on_enter_completed(self):
...         print("Completed!")

See States from Enum types.

Bugfixes in 2.1.0

  methods used as Actions decorated with functools.partial.
