aiohttp: get current running app

Question

Currently I'm doing the following to get the current running app

async def handler(request):
    app = request.app

Isn't there another way for getting the current running app? Consider the below snippet (the default for author_id):

class Comment(DeclarativeBase):
    author_id = Column(Integer, ForeignKey('member.id'), default=Member.current_logged_in()) 

class Member(DeclarativeBase):
    @classmethod
    def current_logged_in()
        pass

As the session is kept in the current running app and as you can see it is only accessible from the incoming request, how can I get the current running app to use the session for determining the current_logged_in user and thus be used as the default value for Comment's author_id? I wish I have made my point.

Right now there is no implicit context for aiohttp application.

BTW don't do synchronous calls (SQLAlchemy ORM in your case) from aiohttp code.
