django-logic - easy way to implement state-based business logic

Django Logic is a lightweight workflow framework aims to solve an open problem "Where to put the business logic in Django?".

The Django-Logic package provides a set of tools helping to build a reliable product within a limited time. Here is the functionality the package offers for you:

• Implement state-based business processes combined into Processes.
• Provides a business logic layer as a set of conditions, side-effects, permissions, and even celery-tasks combined into a transition class.
• In progress states
• REST API actions - every transition could be turned into a POST request action within seconds by extending your ViewSet and Serialiser of Django-Rest-Framework
• Form buttons (TODO) - add buttons to your form and templates based on available transitions
• Background side-effects before or after transition executed. It gives you reach functionality to implement complicated business rules without into details.
• Draw your business processes to get a full picture of all transitions and conditions.
• Easy to read the business process
• One and only one way to implement business logic. You will be able to extend and improve the Django-Logic functionality and available handlers. However, the business logic will remain the same and by following SOLID principles.
• Test your business logic by unit-tests as pure functions.
• Protects from overwritten states, locks, etc. already implemented in Django Logic and you could control the behaviour.
• Several states can be combined under the same Model.
