Flask Tutorial #7 - Application Factory Function

Defining a main module entry point is great for development. But, if you plan on releasing your Flask application in a production setting, you need to be using an Application Factory. This tutorial walks you through setting up a basic factory function and using it to launch an instance of your application.

Discovered this video today, thanks for explaining in such a simple way the application factory, I'm sad to see that this was the last video in the series :/ did you ever uploaded them somewhere else? If yes I'd love to watch them.

Very useful, if we don't use sqlalchemy what is the command to register a database.py module in __ini__.py ?

for some reason i face this error...

Error: Could not locate a Flask application. You did not provide the "FLASK_APP" environment variable, and a "wsgi.py" or "app.py" module was not found in the current
directory.

I am hoping you can help. When I use the flask run command I get the following error:
* Serving Flask app 'carbattery'
* Environment: development
* Debug mode: off
Usage: flask run [OPTIONS]
Try 'flask run --help' for help.

Error: Could not import

Any idea what could be causing this error
