Member Portal V2

This is a project driven by @samp20 to build a new member portal to provide Single-Sign-On (SSO) to other Hackspace services.

The current proposed architecture is a Python Flask application with PostgreSQL as the backend database.

• forms: WTForms.
• models: SQLAlchemy models.
• static: Static files, e.g. css.
• systems: Core systems, e.g. Session, OAuth, JWK.
• templates: Jinja templates.
• tests: Tests. Mainly for systems.
• views: Flask Blueprints with routes. Glue between templates and systems.

Systems will follow a similar style to Flask extensions. Flask requires that extensions don't store state directly on the class itself, but instead obtain it from the current_app. This allows multiple applications to be instantiated, for example when unit testing.

class _State:
    def __init__(self, app: Flask):
        self.greeting: str = app.config["MYSYSTEM_GREETING"]
 
class MySystem:
    def __init__(self, other: OtherSystem, app: Flask|None):
        self.other = other
 
        if app is not None:
            self.init_app(app)
 
    def init_app(self, app: Flask):
        state = _State(app)
        app.extensions["hs.portal.my_system"] = state
 
    @property
    def state(self) -> _State:
        state = current_app.extensions["hs.portal.session"]
        return state
 
    def get_greeting(self) -> str:
        return self.state.greeting
