How to create (in Flask using flask-SA etc.) an SQLite DB file with metadata.create_all(..)

Question

I have a flask application spread across modules with blueprints. Each module/blueprint has its own models.py file where models are defined.

When the application runs, I would like SQLAlchemy to create the SQLite file at the location set with SQLALCHEMY_DATABASE_URI configuration.

With a regular Python application without any extraction layers above SA using base.metadata.create_all(..)

How can I do this with Flask and SQLAlchemy extension?

Answer 1

I suspect you have somewhere :

db = SQLAlchemy(app)

so all you have to do is

db.create_all()
