What is jawanndenn?
===================
.. figure:: https://raw.githubusercontent.com/hartwork/jawanndenn/master/jawanndenn-setup.png
:alt: Screenshot of poll creation in jawanndenn
*jawanndenn* is a simple web application to schedule meetings and run
polls, a libre alternative to Doodle. It is using the following technology:
- Python
- `Docker Compose`_
- `Django`_
- `Django Extensions`_
- `Django Ratelimit`_ + `msgpack-python`_
- `django-redis`_
- `Django REST framework`_
- `Factory Boy`_
- `Gunicorn`_ + `gunicorn-color-logger`_
- `parameterized`_
- `pre-commit`_
- `python-rapidjson`_
- `sentry-python`_
- `wait-for-it`_
- JavaScript / CSS / Fonts
- `Google Webfonts Helper`_
- `jQuery`_
- `jQuery noty`_
- `Materialize`_
- `Roboto`_
- Storage
- `PostgreSQL`_
- `Redis`_
- `SQLite`_
- Scheduling
- `Supercronic`_
*jawanndenn* is `libre software`_ developed by `Sebastian Pipping`_. The
server code is licensed under the `GNU Affero GPL license`_ version 3
or later whereas the client code is licensed under the `GNU GPL
license`_ version 3 or later.
Please `report bugs`_ and let me know if you `like`_ it.
Poll Setup Format
=================
The textarea titled "Setup (JSON)" uses
a simple `JSON`_-based format that knows the following keys:
- ``equal_width`` — a bool to control whether all options are pumped up
to the same width (``true`` or ``false``) to counter potential voter bias
- ``lifetime`` — duration after which this poll will be deleted;
can be ``"week"`` or ``"month"``; an enum-like string
- ``options`` — a list of strings, one for each option;
supports `Markdown`_-like syntax for: bold, italic, inline code
- ``title`` — the title or headline of the poll to run;
supports `Markdown`_-like syntax for: bold, italic, inline code
Installation
============
To install the latest release without cloning the Git repository:
::
# pip3 install jawanndenn --user
To install from a Git clone:
::
# ./setup.py install --user
Deployment with docker-compose
==============================
Create a simple file ``.env`` like this one:
::
JAWANNDENN_POSTGRES_NAME=jawanndenn
JAWANNDENN_POSTGRES_USER=jawanndenn
JAWANNDENN_POSTGRES_PASSWORD=dEb2PIcinemA8poH
JAWANNDENN_SECRET_KEY=606ea88f183a27919d5c27ec7f948906d23fdd7821684eb59e8bcf7377e3853b
Make sure to **adjust these values** after copy and paste!
You can then build and run a docker image using ``docker-compose up --build``.
The app is served on ``localhost:54080``.
PostgreSQL data is saved to ``~/.jawanndenn-docker-pgdata/`` on the host system.
There is also an instance of Redis used for cross-process rate limiting,
and a "cron" housekeeping container that will go delete polls that have exceeded their
configured lifetime, every 60 minutes.
(If you need a low-maintenance SSL reverse proxy in front of jawanndenn,
`docker-ssl-reverse-proxy `_
could be of interest.)
There is a few more environment variables that you could want to adjust in your environment.
Altogether, there are these variables:
Environment variables

(see ``jawanndenn/settings.py``)
Command line usage
==================
When installed, invocation is as simple as
::
# jawanndenn
During development, you may want to run *jawanndenn* from the Git clone
using
::
# PYTHONPATH=. python3 -m jawanndenn --debug
Currently supported arguments are:
::
# jawanndenn --help
usage: jawanndenn [-h] [--debug] [--host HOST] [--port PORT]
[--url-prefix PATH] [--database-sqlite3 FILE]
[--django-secret-key-file FILE] [--max-polls COUNT]
[--max-votes-per-poll COUNT] [--dumpdata]
[--loaddata FILE.json]
optional arguments:
-h, --help show this help message and exit
--debug Enable debug mode (default: disabled)
--host HOST Hostname or IP address to listen at (default:
127.0.0.1)
--port PORT Port to listen at (default: 8080)
--url-prefix PATH Path to prepend to URLs (default: "")
--database-sqlite3 FILE
File to write the database to (default:
~/jawanndenn.sqlite3)
--django-secret-key-file FILE
File to use for Django secret key data (default:
~/jawanndenn.secret_key)
limit configuration:
--max-polls COUNT Maximum number of polls total (default: 1000)
--max-votes-per-poll COUNT
Maximum number of votes per poll (default: 40)
data import/export arguments:
--dumpdata Dump a JSON export of the database to standard output,
then quit.
--loaddata FILE.json Load a JSON export of the database from FILE.json,
then quit.
Migrating data from jawanndenn 1.x to 2.x
=========================================
Migration takes four steps:
1. Update to the latest version of jawanndenn 1.x, e.g. by running:
``pip2 install --upgrade 'jawanndenn<2'``;
the JSON data export was first introduced with release 1.6.3.
2. Export existing polls:
a) If you're using the commend line app:
``python2 -m jawanndenn --dumpdata > dump.json``
b) If you're using docker-compose:
``docker-compose run -T jawanndenn --database-pickle /data/polls.pickle --dumpdata > dump.json``
3. Deploy latest jawanndenn 2.x somewhere (as described above) or just
``pip3 install 'jawanndenn>=2'``
it somewhere
4. Import the JSON dump created in step (2):
a) If you're using the commend line app:
``python3 -m jawanndenn --loaddata dump.json``
b) If you're using docker-compose:
``docker-compose run -T jawanndenn sh -c 'cat > /tmp/dump.json && DJANGO_SETTINGS_MODULE=jawanndenn.settings python3 -m django loaddata /tmp/dump.json' < dump.json``
Goals
=====
- Libre software to host yourself, unlike Doodle
- More simplistic, sexy and/or fun than `libre alternatives`_, in alphabetic order:
- `Bitpoll`_ (ex. `Dudel`_)
- `Crab Fit`_
- `Croodle`_
- `Dudle`_
- (`Drupal Date picker formatter`_)
- (`Foodle`_ (discontinued; `on GitHub`_, ex. `DFN scheduler`_, ex. `DFN Terminplaner+`_))
- `Framadata`_ (`Sources`_, ex. `OpenSondage`_, ex. `STUdS`_)
- `Nextcloud Polls`_
- `Noodle`_
- `Nuages`_
- `Pleft`_
- `Rallly`_
- `RDVz`_
- `sowhenthen`_
- `VoteOn.Date`_
- Keep things simple, usable, maintainable
- Support invocation from the command line, e.g. for spontaneous polls in a LAN
- Have security in mind
Please check out the `list of upcoming features`_.
Non-goals
=========
- Use of heavy frontend frameworks: building blocks only
- Read availability from calendars
