Application Factory Blueprint Template for Flask Apps

Getting Started:

Open a terminal in the project directory and type the command python3 -m venv .venv
Then enter the virtual environment with source .venv/bin/activate (.venv\Scripts\activate on Windows)
To get all the packages, run pip install -r requirements.txt
Create a .env file in your base directory and add in:

SECRET_KEY=your-secret-key-here

FLASK_APP=app.py
Test your new app by running flask run and typing http://localhost:5000/ into your browser of choice. You should see the 'Hello World!' message.

To initialize your local sqllite db, run flask db init
Then to run your first migration and set the db up, run flask db migrate
A migration versions folder should now be located at your_base_dir/migrations/versions
Check the alembic commands, and if everything looks right, run flask db upgrade to create your first tables
You can run flask db downgrade to undo any and all migrations.
Migration up/downgrades will be run in the sequence they were created.
