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 (trueorfalse) to counter potential voter biaslifetime— duration after which this poll will be deleted; can be"week"or"month"; an enum-like stringoptions— a list of strings, one for each option; supports Markdown-like syntax for: bold, italic, inline codetitle— 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 use your own values!
You can then build and run a docker image using docker-compose up --build.
PostgreSQL data is saved to ~/.jawanndenn-docker-pgdata/ on the host system. The app is served on localhost:54080.
Command line usage
When installed, invocation is as simple as

[--loaddata FILE.json]
optional arguments:

Migrating data from jawanndenn 1.x to 2.x
Migration takes four steps:
- 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. - Export existing polls:
- If you're using the commend line app:
python2 -m jawanndenn --dumpdata > dump.json - If you're using docker-compose:
docker-compose run -T jawanndenn --database-pickle /data/polls.pickle --dumpdata > dump.json
- If you're using the commend line app:
- Deploy latest jawanndenn 2.x somewhere (as described above) or just
pip3 install 'jawanndenn>=2'it somewhere - Import the JSON dump created in step (2):
- If you're using the commend line app:
python3 -m jawanndenn --loaddata dump.json - 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
- If you're using the commend line app:
Goals
- Libre software to host yourself, unlike Doodle
- More simplistic, sexy and/or fun than libre alternatives, in alphabetic order:
- Bitpoll (ex. Dudel)
- 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
- 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
