Castellum Scheduler -- an open source tool for scheduling appointments
Scheduler allows users to set up a set of timeslots and generate unique
invitation links. Each invited person can then pick a free slot without
needing to log in. In a way this is the opposite of doodle where
everyone agrees on the same time slot.
Scheduler is part of the [Castellum][1] project, but can be used with
other tools just as well.
# Installation
For development, a single `make` will install all dependencies and start
the server. You can log in as "admin" with password "password".
If you want to run the scheduler alongside castellum for development you
need to set the following settings in castellum:
SCHEDULER_URL = 'http://localhost:8001'
SCHEDULER_TOKEN = 'CHANGEME'
```
## Production
There are many different ways to deploy a django application. Please see
the [django documentation][2] for details. A complete example is also
availabe in the [castellum documentation][3].
Most important steps:
- Create a settings file and set the `DJANGO_SETTINGS_MODULE`
environment variable accordingly
- Provide values `SECRET_KEY` and `API_TOKEN` in the settings file you
just created
- Setup a database and add the relevant information to the settings
file
- Add links to the imprint and data protection information to `NAV`.
You can either create them with an external CMS or by using [django
flatpages][5].
- Configure authentication, e.g. [LDAP][4]
This system is designed so that castellum can remain in a secure
internal network and only the scheduler is accessible from the internet.
All API requests must send an `Authorization` header with the secret
token defined in `settings.API_TOKEN`.
You can use PUT/DELETE requests to create/delete invitations for a
schedule. PUT will always respond with 204. DELETE will respond with 404
if no matching invitation existed.
You can use a GET request to get the currently selected timeslot for an
invitation.
Example:
$ curl -X PUT -H 'Authorization: token CHANGEME' http://localhost:8001/api/26f4c524-4c74-4788-90c6-889dff86001d/foo/
$ curl -X GET -H 'Authorization: token CHANGEME' http://localhost:8001/api/26f4c524-4c74-4788-90c6-889dff86001d/foo/
$ curl -X GET -H 'Authorization: token CHANGEME' http://localhost:8001/api/26f4c524-4c74-4788-90c6-889dff86001d/
{"foo": "2020-11-03T07:00:00"}
$ curl -X DELETE -H 'Authorization: token CHANGEME' http://localhost:8001/api/26f4c524-4c74-4788-90c6-889dff86001d/foo/
