Basic Flask webapplication to implement CRUD functionality to database.

IMPORTANT

Create a config.json file in the local directory as the app.py

config.json should have the following contents:

{
  "TESTING": "",
  "FLASK_DEBUG": true,
  "SECRET_KEY": "some_really_secret_key",
  "SQLALCHEMY_DATABASE_URI": "postgresql://postgres_username:your_passwd@localhost:5432/TestDB",

Or anything appropriate from flask sqlalchemy database URI. (according to your choice of database) here

  "SQLALCHEMY_TRACK_MODIFICATIONS": false
}

Then run, flask migrate to migrate the database changes.

$ flask db init
$ flask db migrate
$ flask db upgrade

This will create all columns and tables in the databse name provided in the SQLALCHEMY_DATABASE_URI.
