Haldis is your friendly neighbourhood servant. He exists so lazy fucks like you and me don't need to keep tabs of who is ordering what from where. Start an order and let people add items with a simple mouse-click! No more calculating prices and making lists! Be lazier today!

Local setup

There is a special script to get started with the project. Just run it in the root of the project.

./first-setup.sh

This will create a virtual environment, install the necessary dependencies and will give you the option to seed the database.

If you are using a database other then sqlite you will first need to configure the correct URI to the database in the generated 'config.py' file. Afterwards upgrade the database to the latest version using

cd app
python3 app.py db upgrade

You can now still seed the database by running

./populate-db.sh

in the root folder of the project.

Activate the virtual environment using

source venv/bin/activate

Finally run the webserver with

python3 app/app.py runserver

Make sure to use localhost instead of 127.0.0.1 if you want to be able to login.

Development

Changing the database

  1. Update models located in 'app/models.py'
  2. Run python app/app.py db migrate to create a new migration.
  3. Apply the changes to the database using python app/app.py db upgrade

Adding dependencies/libraries

  1. Add new dependency to the requirements.in file
  2. Run pip-compile to freeze the dependency into the requirements.txt file together with its own deps
  3. Run pip-sync to download frozen deps

Updating dependencies

Run pip-compile --upgrade

For more information about managing the dependencies see jazzband/pip-tools: A set of tools to keep your pinned Python dependencies fresh.

Production

To prepare the application in a production environment, follow the same steps as for Local setup up to and including ./populate-db.sh.

Set DEBUG to False in app/config.py.

See Flask's deployment documentation.

Set the server's Python interpreter to /path/to/haldis/venv/bin/python. Doing source venv/bin/activate is not necessary when that binary is used.
