EVOLUTION FORMAT

  1. Lectures/Dicussion from FSA/PAP
  2. Review and Reflection on Previous Evolution.
  3. Orientation to the purpose of the evolution
  4. Q and A about Evolution

EVOLUTION 0: UML + OOP

Please place your Diagrams in the corresponding folder.

EVOLUTION 1: API + Models

API-Centricity (heart of system)

Exercise Make an API for coin toss

Three Ways

  1. Flask
  2. FastAPI
  3. Django Rest Framework

Good reference article: https://www.twilio.com/en-us/blog/create-api-with-python

EVOLUTION 2: REPOSITORY and UoW

Clean and abstracted transactions for all state changes

EVOLUTION 3: Event-Driven Architectures

Balancing state change requests and business rules

EVOLUTION 4: WEB ARCHITECTURES

Leveraging the web as the application framework

EVOLUTION 5: TDD, BDD, DDD

Validation and verificaiton

Putting it All Together for the Final Project

  • Django app that uses:
    • Django Architecture - MVC/MVT
    • Django Rest Framework for API Development
    • Django O/RM to get some of the benefits of the repository pattern
    • Django, Celery, and Redis for Message Queueing and Event Tasking
    • Django Unit Tests for TDD, BDD, DDD

Expectations:

  1. Use Django for your models, views, and monolithic architecture
  2. Use the Django Rest Framework for API Routing and Serliazation
  3. Use Django, Celery, and Redis for message/task queuing
  4. Use built-in unit testing for TDD, BDD, DDD

Evolutions 0 and 5

  • Ensure that the behaviors and structures of your app are represented by:
    • UML diagrams - class, seqeuence, activity, state, use case
    • Provide a glossary of the Ubiquitous Language that is embedded in your project Developing the ubiquitous language
    • Create testable stories and acceptance criteria, using the BDD Gherkin syntax, to develop your unit tests. Read: What is BDD?
    • Ensure you create tests that reflect the Gherkin Syntax feature design statements from the link above.

Evolution 1

Evolution 2

  • Use Django Models and DRF Serializers to provide CRUD operations for your entities

Evolution 3

  • Use Celery and Redis to create a message/event and task queue to execute asynchronous tasks in your application.

Evolution 4

  • Django serves as our comprehensive application/project framework for our entire architecture. Bear in mind that this is a monolithic architecture as opposed to a service-based (microservices) architecture.

Fixtures

Data that loads up my simple examples has been exported using the following Django command:

python manage.py dumpdata api --format json --indent 4 --output ./api/fixtures/api_fixtures.json

Use the loaddata django management command to import this fixture.
