QFieldCloud is a Django based service designed to synchronize projects and data between QGIS (+ QFieldSync plugin) and QField.

QFieldCloud allows seamless synchronization of your field data with your spatial infrastructure with change tracking, team management and online-offline work capabilities in QField.

If you're interested in quickly getting up and running, we suggest subscribing to the version hosted by OPENGIS.ch at https://qfield.cloud. This is also the instance that is integrated by default into QField.

QField and QFieldCloud documentation is deployed here.

If you are interested in upcoming developments, or you want to suggest a new feature, please visit our ideas platform at ideas.qfield.org. Here, you can submit a new request or upvote existing ones. To expedite developments by funding a feature, please email us at [email protected].

For questions about using the hosted service at app.qfield.cloud, submit a ticket to our dedicated support platform at tickets.qfield.cloud.

For self-hosted issues, please use the GitHub issues at https://github.com/opengisch/qfieldcloud/issues .

Clone the repository and all its submodules:

git clone --recurse-submodules [email protected]:opengisch/QFieldCloud.git

To fetch upstream development, don't forget to update the submodules too:

git pull --recurse-submodules  && git submodule update --recursive

Copy the .env.example into .env file and configure it to your desire with a good editor:

cp .env.example .env
emacs .env

Make sure the host's firewall allows port 8009, required by the minio service. Failing to meet this requirement is likely to result in the service being unable to start.

To build development images and run the containers:

docker compose up -d --build

It will read the docker-compose*.yml files specified in the COMPOSE_FILE variable and start a django built-in server at http://localhost:8011.

Run the django database migrations.

docker compose exec app python manage.py migrate

And collect the static files (CSS, JS etc):

docker compose run app python manage.py collectstatic --noinput

You can check if everything seems to work correctly using the status command:

docker compose exec app python manage.py status

Now you can get started by adding the first user that would also be a super user:

docker compose run app python manage.py createsuperuser --username super_user --email [email protected]

QFieldCloud uses pip-compile to manage it's dependencies. All dependencies are listed in requirements*.in files. When a pip a dependency is changed, the developer should produce the new requirements*.txt files.

docker compose run --rm pipcompile

Alterantively, one can create only a requirements.txt file for a single requirements.in:

docker compose run --rm pipcompile pip-compile --no-strip-extras -o requirements/requirements_worker_wrapper.txt requirements/requirements_worker_wrapper.in

Rebuild the docker compose stack with the docker-compose.override.test.yml file added to the COMPOSE_FILE environment variable:

export COMPOSE_FILE=docker-compose.yml:docker-compose.override.standalone.yml:docker-compose.override.test.yml
# (Re-)build the app service to install necessary test utilities (requirements_test.txt)
docker compose up -d --build
docker compose run app python manage.py migrate
docker compose run app python manage.py collectstatic --noinput

You can then run all the unit and functional tests:

docker compose run app python manage.py test --keepdb

To run only a test module (e.g. test_permission.py):

docker compose run app python manage.py test --keepdb qfieldcloud.core.tests.test_permission

To run a specific test:

docker compose run app python manage.py test --keepdb qfieldcloud.core.tests.test_permission.QfcTestCase.test_collaborator_project_takeover

This section gives examples for VSCode, please adapt to your IDE)

If you are using the provided docker-compose.override.local.yml, then debugpy is automatically installed and configured for use.

Add the following to your IDE to connect (example given for VSCode's .vscode/launch.json, triggered with F5):

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "QFC debug app",
            "type": "python",
            "request": "attach",
            "justMyCode": false,
            "connect": {"host": "localhost", "port": 5678},
            "pathMappings": [
                {
                    "localRoot": "${workspaceFolder}/docker-app/qfieldcloud",
                    "remoteRoot": "/usr/src/app/qfieldcloud"
                },
                {
                    "localRoot": "${workspaceFolder}/docker-app/site-packages",
                    "remoteRoot": "/usr/local/lib/python3.10/site-packages/"
                },
            ],
        },
        {
            "name": "QFC debug worker_wrapper",
            "type": "python",
            "request": "attach",
            "justMyCode": false,
            "connect": {"host": "localhost", "port": 5679},
            "pathMappings": [
                {
                    "localRoot": "${workspaceFolder}/docker-app/qfieldcloud",
                    "remoteRoot": "/usr/src/app/qfieldcloud"
                },
                {
                    "localRoot": "${workspaceFolder}/docker-app/site-packages",
                    "remoteRoot": "/usr/local/lib/python3.10/site-packages/"
                },
            ],
        }
    ]
}

To add breakpoints in vendor modules installed via pip or apt, you need a copy of their source code. The easiest way to achieve that is do actual copy of them:

docker compose cp app:/usr/local/lib/python3.10/site-packages/ docker-app/site-packages

The configuration for the vendor modules is the second object in the example pathMappings above, as well as setting justMyCode to false.

Do not forget to copy the site packages every time any of the requirements.txt files are changed!

If you are not using docker-compose.override.local.yml, there are other options.

You can debug interactively by adding this snippet anywhere in the code.

import debugpy
debugpy.listen(("0.0.0.0", 5680))
print("debugpy waiting for debugger... 🐛")
debugpy.wait_for_client()  # optional

Or alternativley, prefix your commands with python -m debugpy --listen 0.0.0.0:5680 --wait-for-client.

docker compose run -p 5680:5680 app python -m debugpy --listen 0.0.0.0:5680 --wait-for-client manage.py test
docker compose run -p 5681:5681 worker_wrapper python -m debugpy --listen 0.0.0.0:5681 --wait-for-client manage.py test

Note if you run tests using the docker-compose.test.yml configuration, the app and worker-wrapper containers expose ports 5680 and 5681 respectively.

QFieldCloud will automatically generate a certificate and its root certificate in ./conf/nginx/certs. However, you need to trust the root certificate first, so other programs (e.g. curl) can create secure connection to the local QFieldCloud instance.

On Debian/Ubuntu, copy the root certificate to the directory with trusted certificates. Note the extension has been changed to .crt:

sudo cp ./conf/nginx/certs/rootCA.pem /usr/local/share/ca-certificates/rootCA.crt

Trust the newly added certificate:

sudo update-ca-certificates

Connecting with curl should return no errors: curl https://localhost:8002/

If you want to remove or change the root certificate, you need to remove the root certificate file and refresh the list of certificates:

sudo rm /usr/local/share/ca-certificates/rootCA.crt
sudo update-ca-certificates --fresh

Now connecting with curl should fail with a similar error:

$ curl https://localhost:8002/

curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

Code style done with precommit:

pip install pre-commit
# install pre-commit hook
pre-commit install

Copy the .env.example into .env file:

cp .env.example .env
vi .env

Do not forget to set DEBUG=0 and to adapt COMPOSE_FILE environment variable to not load local development configurations.

Run and build the docker containers:

docker compose up -d --build

Run the django database migrations:

docker compose exec app python manage.py migrate

Collect the static files:

docker compose exec app python manage.py collectstatic

By default, QFieldCloud is using a self-signed certificate. For production use you should use a valid certificate.

Note you want to change the LETSENCRYPT_EMAIL, LETSENCRYPT_RSA_KEY_SIZE and LETSENCRYPT_STAGING variables in .env.

On a server with a public domain, you can get a certificate issued by Let's Encrypt using certbot running the following command:

./scripts/init_letsencrypt.sh

The certificates will be renewed automatically.

To use this Let's Encrypt certificate within QFieldCloud you just need to uncomment the following lines in your .env:

QFIELDCLOUD_TLS_CERT=/etc/letsencrypt/live/${QFIELDCLOUD_HOST}/fullchain.pem
QFIELDCLOUD_TLS_KEY=/etc/letsencrypt/live/${QFIELDCLOUD_HOST}/privkey.pem

You can also use your own certificates by placing them in conf/nginx/certs/ and changing QFIELDCLOUD_TLS_CERT and QFIELDCLOUD_TLS_KEY accordingly. Don't forget to create your Diffie-Hellman parameters.

You can add additional config to nginx placing files in conf/nginx/config.d/ ending with .conf. They will be included in the main nginx.conf.

Based on this example https://testdriven.io/blog/dockerizing-django-with-postgres-gunicorn-and-nginx/

Docker logs are managed by docker in the default way. To read the logs:

docker compose logs

For great nginx logs, use:

QFC_JQ='[.ts, .ip, (.method + " " + (.status|tostring) + " " + (.resp_time|tostring) + "s"), .uri, "I " + (.request_length|tostring) + " O " + (.resp_body_size|tostring), "C " + (.upstream_connect_time|tostring) + "s", "H " + (.upstream_header_time|tostring) + "s", "R " + (.upstream_response_time|tostring) + "s", .user_agent] | @tsv'
docker compose logs nginx -f --no-log-prefix | grep ':"nginx"' | jq -r $QFC_JQ

The geodb (database for the users projects data) is installed on separated machines (db1.qfield.cloud, db2.qfield.cloud, db3…) and they are load balanced and available through the db.qfield.cloud address.

There is a template database called template_postgis that is used to create the databases for the users. The template db has the following extensions installed:

• fuzzystrmatch
• plpgsql
• postgis
• postgis_{tigergeocoder}
• postgis_topology

You can use either the integrated minio object storage, or use an external provider (e. g. S3) with versioning enabled. Check the corresponding STORAGE_* environment variables for more info.
