pyramid_autowire is a package that allows your pyramid views to use pyramids registry for dependency injection.

from pyramid_autowire import autowired

@view_defaults(route_name='test_route', mapper=autowired)
class Posts:
    def __init__(
        # Standard pyramid (context, request) and (request,) arguments
        # are available through position-only args
        self, request, /,
        # the database and user objects will be injected from the registry
        database: IDatabase, active_user: IUser
    ):
        self.request = request
        self.database = database
        self.active_user = active_user

    @view_config()
    def view_post(
        self, *,
        # the matchdict is injected as keyword-only args
        post_id
    ):
        return self.database.query(Post, post_id)

def includeme(config):
    registry = config.registry

    # pretend for the example that the database session is global
    registry.registerUtility(MyDatabase(), IDatabase)

    def get_active_user(request):
        # Fetch active user from the request data
        ...

    registry.registerAdapter(get_active_user, (IRequest, ), IUser)
