App-Factory | OS X app that allows the easy conversion

I'm not able to create tables into a database (PostgresSQL) when using Flask's app factory pattern.

I've looked at different examples from Stackoverflow and the Flask-SQLAlchemy source code. My understanding is that with the factory app pattern, I need to set up the so-called context before I can try creating the tables. However, when I create the context, Flask app's config dictionary gets reset and it doesn't propagate the configurations forward.

Here's my model.py

I try to build a reusable list which displays elements of type T. The view of these elements depends on T. To break this dependency I decided to also pass the view component.

E.g. The list contains elements of type "Car". The view passing to this list is used to display the attributes ".ps" and ".color" of each element.

Sadly, I am a Newbie in Angular and I can't figure how to do this right. I would like to do something like this:

generic-list.ts

My Flask Application is crashing when I'm trying to access it.

This is similar error to this or this. However, my set-up seems correct.

flask.cli.NoAppException: The file/path provided (server) does not appear to exist. Please verify the path is correct. If app is not on PYTHONPATH, ensure the extension is .py

My environment variable correctly set.
