TOP app (Toezicht op pad)

Dankzij de TOP app hebben toezichthouders Wonen veel informatie over zaken, adressen en bewoners bij de hand als zij op straat hun werk doen. Ook kunnen zij hun eigen looplijst samenstellen, op basis van instellingen die planners hebben klaargezet.

Steps for local development

Prerequisites

• Docker

Build

docker compose -f docker-compose.local.yml build

Creating networks

Before running the project, you need to create the networks:

docker network create top_network
docker network create top_and_zaak_backend_bridge

Starting the development server

Start the dev server for local development:

docker compose -f docker-compose.local.yml up

Importing & generating data

This project needs some data configuration in order to run locally. It's possible to add this manually, but the quickest way is to import fixtures and generate day settings for all teams.

Step 1: Import fixtures

First, import fixtures. This will add planner data, like teams, postal codes and visit configurations:

docker compose -f docker-compose.local.yml exec api python manage.py loaddata fixture

Note: you can also download updated fixture data from the acceptance environment. You'll need to be logged in using an admin account first to access this url.

Click on "DOWNLOAD JSON FIXTURE". Move the JSON file into the app directory on the root of your project, and run the above command with the filename (top-planner-<date>.json) appended to it. Remove the JSON fixture after importing it.

Step 2a: Provide zaak-gateway data (optional)

For step 2b to be able to generate all data properly, it is important that data from the zaak-gateway is available:

• Either make sure the ZAKEN_API_URL from the .env is reachable. You can do this by by running the zaak-gateway from the zaken-backend repo.
• If you're unable to do so, add USE_ZAKEN_MOCK_DATA=True to your local .env.local to make use of some mock data, but this may result in data inconsistencies later on.

Note: if you're not running the zaak-gateway or haven't enabled mock data, the next command will still fill most data. In that case "team schedules" and "reasons" will not be available and therefore generated.

Step 2b: Generate planner data

Finally, generate planner day settings for each team. Do this by running the planner generate_daysettings command:

docker compose -f docker-compose.local.yml exec api python manage.py generate_daysettings

Note: if you'd like to clean up and delete existing day settings, append the --cleanup flag to the above command.

Creating a superuser

For accessing the Django admin during local development you'll have to become a superuser. This user should have the same email and username as the one that will be auto-created by the SSO login.

Run the following command to either create the user, or make the existing one a superuser:

sh bin/setup_superuser.sh <email>

Accessing the Django admin and adding users:

In order to generate lists you need at least 2 other users. You can add other users easily through the Django admin.

Navigate to http://localhost:8000/admin and sign in using the superuser you just created. Once you're in the admin, you can click on "add" in the User section to create new users.

Accessing the API documentation

You can access the documentation at: http://localhost:8000/api/v1/swagger/

Bypassing Keycloak and using local development authentication

It's possible to bypass Keycloak authentication when running the project locally.
To do so, create .env.local file with:

LOCAL_DEVELOPMENT_AUTHENTICATION=False

Bypassing multiprocessing and use threads

The algorithm uses multiprocessing to select cases for a list. Multiprocessing sometimes freezes during local development. You will see a database SSL error:

SSL error: decryption failed or bad record mac could not receive data from client: Connection reset by peer unexpected EOF on client connection with an open transaction

To fix this use threads instead by creating/updating your .env.local file:

LOCAL_DEVELOPMENT_USE_MULTIPROCESSING=False

Running commands

Run a command inside the docker container:

docker compose run --rm api [command]

Running migrations:

docker compose run --rm api python manage.py migrate

Adding pre-commit hooks

You can add pre-commit hooks for checking and cleaning up your changes:

bash install.sh

You can also run the following command to ensure all files adhere to coding conventions:

bash cleanup.sh

This will autoformat your code, sort your imports and fix or find overal problems.

The Github actions will use the same bash script to check if the code in the pull requests follows the formatting and style conventions.

Coding conventions and style

The project uses Black for formatting and Flake8 for linting.

Testing

Running unit tests

Unit tests can be run using the following command:

docker compose -f docker-compose.local.yml run --rm api python manage.py test

To run tests for a specific module, add a path:

docker compose -f docker-compose.local.yml run --rm api python manage.py test apps/cases

Unit test in pull requests

Unit tests are part of the Github action workflows, and will be run when a pull request is made. This ensures tests are maintained and increases maintainability and dependability of automatic pull requests.
