AK Planning

Description

AKPlanning is a tool used for modeling, submitting, scheduling and displaying AKs (German: Arbeitskreise), meaning workshops, talks or similar slot-based events.

It was built for KIF (German: Konferenz der deutschsprachigen Informatikfachschaften), refer to the wiki for more Information.

Setup

This repository contains a Django project with several apps.

Requirements

AKPlanning has two types of requirements: System requirements are dependent on operating system and need to be installed manually beforehand. Python requirements will be installed inside a virtual environment (strongly recommended) during setup.

System Requirements

• Python 3.7 incl. development tools
• Virtualenv
• for production using uwsgi:
  • C compiler e.g. gcc
  • uwsgi
  • uwsgi Python3 plugin
• for production using Apache (in addition to uwsgi)
  • the mod proxy uwsgi plugin for apache2

Python Requirements

Python requirements are listed in requirements.txt. They can be installed with pip using -r requirements.txt.

Development Setup

• create a new directory that should contain the files in future, e.g. mkdir AKPlanning
• change into that directory cd AKPlanning
• clone this repository git clone URL .

Automatic Setup

1. execute the setup bash script Utils/setup.sh

Manual Setup

1. setup a virtual environment using the proper python version virtualenv venv -p python3.7
2. activate virtualenv source venv/bin/activate
3. install python requirements pip install -r requirements.txt
4. setup necessary database tables etc. python manage.py migrate
5. prepare static files (can be omitted for dev setups) python manage.py collectstatic
6. compile translations python manage.py compilemessages
7. create a priviledged user, credentials are entered interactively on CLI python manage.py createsuperuser
8. deactivate virtualenv deactivate

Development Server

To start the application for development use python manage.py runserver 0:8000 from the root directory. Do not use this for deployment!

In your browser, access http://127.0.0.1:8000/ and continue from there.

Deployment Setup

This application can be deployed using a web server as any other Django application. Remember to use a secret key that is not stored in any repository or similar, and disable DEBUG mode (settings.py).

Step-by-Step Instructions

1. log into your system with a sudo user

2. install system requirements

3. create a folder, e.g. mkdir /srv/AKPlanning/

4. change to the new directory cd /srv/AKPlanning/

5. clone this repository git clone URL .

6. setup a virtual environment using the proper python version virtualenv venv -p python3.7

7. activate virtualenv source venv/bin/activate

8. update tools pip install --upgrade setuptools pip wheel

9. install python requirements pip install -r requirements.txt

10. create the file AKPlanning/settings_secrets.py (copy from settings_secrets.py.sample) and fill it with the necessary secrets (e.g. generated by tr -dc 'a-z0-9!@#$%^&*(-_=+)' < /dev/urandom | head -c50) (it is a good idea to restrict read permissions from others)

11. if necessary enable uwsgi proxy plugin for Apache e.g.a2enmod proxy_uwsgi

12. edit the apache config to serve the application and the static files, e.g. on a dedicated system in /etc/apache2/sites-enabled/000-default.conf within the VirtualHost tag add:

    Alias /static /srv/AKPlanning/static
    <Directory /srv/AKPlanning/static>
    Require all granted
    </Directory>
    
    ProxyPassMatch ^/static/ !
    ProxyPass / uwsgi://127.0.0.1:3035/

    or create a new config (.conf) file (similar to apache-akplanning.conf) replacing $SUBDOMAIN with the subdomain the system should be available under, and $MAILADDRESS with the e-mail address of your administrator and $PATHTO with the appropriate paths. Copy or symlink it to /etc/apache2/sites-available. Then symlink it to sites-enabled e.g. by using ln -s /etc/apache2/sites-available/akplanning.conf /etc/apache2/sites-enabled/akplanning.conf.

13. restart Apache sudo systemctl restart apache2.service

14. create a dedicated user, e.g. adduser django

15. transfer ownership of the folder to the new user chown -R django:django /srv/AKPlanning

16. Copy or symlink the uwsgi config in uwsgi-akplanning.ini to /etc/uwsgi/apps-available/ and then symlink it to /etc/uwsgi/apps-enabled/ using e.g., ln -s /srv/AKPlanning/uwsgi-akplanning.ini /etc/uwsgi/apps-available/akplanning.ini and ln -s /etc/uwsgi/apps-available/akplanning.ini /etc/uwsgi/apps-enabled/akplanning.ini start uwsgi using the configuration file uwsgi --ini uwsgi-akplanning.ini

17. restart uwsgi sudo systemctl restart uwsgi

18. execute the update script ./Utils/update.sh --prod

Updates

To update the setup to the current version on the main branch of the repository use the update script Utils/update.sh or Utils/update.sh --prod in production.

Afterwards, you may check your setup by executing Utils/check.sh or Utils/check.sh --prod in production.

Structure

This repository contains a Django project called AKPlanning. The functionality is encapsulated into Django apps:

1. AKModel: This app contains the general Django models used to represent events, users, rooms, scheduling constraints etc. This app is a basic requirements for the other apps. Data Import/Export also goes here.
2. AKDashboard: This app provides a landing page for the project. Per Event it provides links to all relevant functionalities and views.
3. AKSubmission: This app provides forms to submit all kinds of AKs, edit or delete them, as well as a list of all submitted AKs for an event.
4. AKScheduling: This app allows organizers to schedule AKs, i.e. assigning rooms, slots, etc. It marks conflicts of all modeled constraints and assists in creating a suitable schedule.
5. AKPlan: This app displays AKs and where/when they will take place for each event. Views are optimised according to usage/purpose.

Developer Notes

• to regenerate translations use python manage.py makemessages -l de_DE --ignore venv
• to create a data backup use python manage.py dumpdata --indent=2 > db.json --traceback
