tourist-with-flask

An implementation of the Underwater Hockey Tourist using Flask. See the live site at https://pucku.org/tourist/.

This page is for people who are interested in changing the code that runs the hockey tourist. If you'd like to improve our list of clubs please read https://pucku.org/tourist/about.

Run your own instance in the cloud

You can now run and modify your own instance entirely in the cloud! When logged into github go to https://github.com/TomGoBravo/tourist-with-flask/ and look for the green <> Code button. Click on it, then Create codespace. After about 20 seconds there should be terminal with a prompt that looks like root@codespaces-60d6e9:/workspaces/tourist-with-flask# . Run flask --debug run, then look for the green Open in browser button. When that opens you are connected to your own private instance of the tourist. Explore and modify the source in the left panel, this is a safe place to experiment.

Run a frontend and prefect instance locally with docker

If you can't use codespace to run an instance in the cloud, you can run the same container on your local machine.

• Install docker on your machine.
• Checkout the git repo https://github.com/TomGoBravo/tourist-with-flask.
• Run docker compose -f .devcontainer/compose.yaml up to start 3 containers: flask, the prefect agent and prefect server.
• Visit http://127.0.0.1:5001/tourist/ to browse the flask server.
• Run tests in the container with docker compose -f .devcontainer/compose.yaml run flaskdebugrun python -m pytest tourist/tests
• To deploy the prefect flow run docker compose -f .devcontainer/compose.yaml run prefectagentdev flask sync deploy-dataflow
• Visit http://127.0.0.1:4200 and run the flow you just deployed.
• Modify the files you checked out from github in the tourist/ directory. The docker container mounts this directory on your host machine inside the container. Some changes trigger an automatic reload, others may need you to restart the container.

Run flask in a local venv

Use this method if you are changing the dependencies or manually making a docker image.

First install pyenv. Don't miss pyenv Common-build-problems. Then try the following which works in debian 11:

PYTHON_CONFIGURE_OPTS="--enable-loadable-sqlite-extensions" pyenv install 3.10.7
pyenv virtualenv 3.10.7 tourist-3.10.7
pyenv activate tourist-3.10.7
python -m pip install pip==21.3  # Work around for https://github.com/jazzband/pip-tools/issues/1639
python -m pip install pip-tools
pip-sync

# Run tests
python -m pytest tourist/tests/

./.devcontainer/setup-dev-data.sh

# Start dev server
FLASK_APP=tourist flask --debug run
