Scaffold for a basic Flask app using SQLAlchemy with example CRUD operations

Flask SQLAlchemy Basic CRUD

This is a scaffold app for use by my SharpKidsCode students to build basic CRUD using Flask and SQLAlchemy

Requirements

Please make sure you have Python 3 installed.

Pyenv

Remember to cerate a Virtual Environment to run python. It's a good practice for any app you're building, so that you can isolate dependencies by app, and build a requirements file unique to each app's unique needs.

It's customary to call that virtual environment 'venv', and here's how you'd do it from the root of your app's folder: python -m venv venv

Then you switch to using the python installed in your virtual environment: source ./venv/bin/activate

To deactivate your virtual environment (and switch back to global python): deactivate

First steps

Install the required dependencies. You can do this via the following command when you're at the root of the application in your Terminal:

pip install -r requirements.txt

Creating the database

While the code already contains a complete DB, you can re-create it anytime. Run Python in the root directory of the app, and then run:

• from app import db
• db.create_all()
• quit()

That should create an app.sqlite3 file in the root directory of your app with the models for Users and Prefs created.

Running the app

python app.py
