OPTIMETA Portal - OPTIMAP

to https://github.com/GeoinformationSystems/optimap/

Geospatial discovery of research articles based on open metadata. The OPTIMETA Portal is part of the OPTIMETA project (https://projects.tib.eu/optimeta) and relies on the spatial and temporal metadata collected for scientific papers with the OPTIMETA Geo Plugin for Open Journal Systems (OJS) published at https://github.com/TIBHannover/optimetaGeo. The product name of the portal is OPTIMAP.

The OPTIMAP has the following features:

• Start page with a full screen map (showing geometries and metadata) and a time line of the areas and time periods of interest for scientific publications
• Passwordless login via email
• RESTful API at /api

OPTIMAP is based on Django (with GeoDjango and Django REST framework) with a PostgreSQL/PostGIS database backend.

Configuration

All configuration is done via the file optimetaPortal/settings.py. Configurations that need to be changed for different installations and for deployment are also exposed as environment variables. The names of these environment variables start with OPTIMAP_. The settings files loads these from a file .env stored in the same location as settings.py, or from the environment the server is run it. A complete list of existing parameters is provided in the file optimetaPortal/.env.example.

Run with Docker

docker-compose up

# run migrations, in the directory where docker-compose is to resolve the name "web"
docker-compose run web python manage.py makemigrations
docker-compose run web python manage.py migrate

Now open a browser at http://localhost:8000/.

Development

Test data

The folder /fixtures contains some test data, either as an SQL command to insert into the database, or as a database dump that was created and can be loaded with django-admin. jq is used for pretty-printing of the output.

# create dump after creating/harvesting test data:
python manage.py dumpdata --exclude=auth --exclude=contenttypes | jq > fixtures/test_data.json

# load:
python manage.py loaddata fixtures/test_data.json

Run locally

Create a .env file based on .env.example in the same directory where settings.py resides and fill in the configuration settings as needed.

# once onle: create virtual environment
# mkvirtualenv optimetaPortal
workon optimetaPortal

pip install -r requirements.txt

# create and start local DB (once)
docker run --name optimetaPortalDB -p 5432:5432 -e POSTGRES_USER=optimeta -e POSTGRES_PASSWORD=optimeta -e POSTGRES_DB=optimetaPortal -d postgis/postgis:14-3.3
# stop and restart it with
# docker stop optimetaPortalDB
# docker start optimetaPortalDB

# run migrations
python manage.py makemigrations
python manage.py migrate

# create cache table
python manage.py createcachetable

# collect static files
python manage.py collectstatic --noinput

# start app
python manage.py runserver

# start app with configuration for development
OPTIMAP_CACHE=dummy OPTIMAP_DEBUG=True python manage.py runserver

Now open a browser at http://127.0.0.1:8000/.

Debug with VS Code

Select the Python interpreter created above (optimetaPortal environment), see instructions at https://code.visualstudio.com/docs/python/tutorial-django.

Configuration for debugging with VS Code:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Django Run",
            "type": "python",
            "request": "launch",
            "program": "${workspaceFolder}/manage.py",
            "args": [
                "runserver"
            ],
            "env": {
                "OPTIMAP_DEBUG": "True",
                "OPTIMAP_CACHE": "dummy"
            },
            "django": true,
            "justMyCode": true
        }
    ]
}

Debug email sending

Add EMAIL_BACKEND=django.core.mail.backends.console.EmailBackend to the .env file to have emails printed to the console instead of sent via SMTP.

Alternatively, you can run a local STMP server with the following command and configuration:

python -m smtpd -c DebuggingServer -n localhost:5587

OPTIMAP_EMAIL_HOST=localhost
OPTIMAP_EMAIL_PORT=5587

Create superusers/admin

Superusers/admin can be created using the createsuperuser command:

python manage.py createsuperuser --username=joe --email=joe@example.com

You will be prompted for a password. After you enter one, the user will be created immediately. If you leave off the --username or --email options, it will prompt you for those values.

You can acess the admin page at http://127.0.0.1:8000/admin/.

You can also run the command in a containerised app with docker-compose run web python manage.py ....

Run tests

See https://docs.djangoproject.com/en/4.1/topics/testing/overview/ for testing Django apps.

UI tests are based on Helium (because Pylenium would need pytest in addition).

pip install -r requirements-dev.txt

python manage.py test tests

# show deprecation warnings
python -Wa manage.py test

# running UI tests needs either compose configuration or a manage.py runserver in a seperate shell
docker-compose up --build

python -Wa manage.py test tests-ui

Develop tests

For developing the UI tests, you can remove the headless=True in the statements for starting the browsers so you can "watch along" and inspect the HTML when a breakpoint is hit as the tests are executed.

Debug tests with VS Code

A configuration to debug the test code and also print deprecation warnings:

{
    "name": "Python: Django Test",
    "type": "python",
    "request": "launch",
    "pythonArgs": [
        "-Wa"
    ],
    "program": "${workspaceFolder}/manage.py",
    "args": [
        "test",
        "tests"
    ],
    "env": {
        "OPTIMAP_DEBUG": "True"
    },
    "django": true,
    "justMyCode": true
}

Change the argument tests to tests-ui to run the UI tests.
