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 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 env -p python3.7
2. activate virtualenv source env/bin/activate
3. install python requirements pip install -r requirements.txt
4. setup necessary database tables etc. python manage.py migrate
5. create a priviledged user, credentials are entered interactively on CLI python manage.py createsuperuser
6. 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 env -p python3.7

7. activate virtualenv source env/bin/activate

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

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

10. install uwsgi pip install uwsgi

11. 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)

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

13. 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 under /etc/apache2/sites-available, fill it with something like:

    <VirtualHost *:80>
    
      ServerName $SUBDOMAIN
    
      ServerAdmin $MAILADDRESS
    
      ErrorLog ${APACHE_LOG_DIR}/error.log
      CustomLog ${APACHE_LOG_DIR}/access.log combined
    
      Alias /static /srv/AKPlanning/static
      <Directory /srv/AKPlanning/static>
      Require all granted
      </Directory>
    
      ProxyPassMatch ^/static/ !
      ProxyPass / uwsgi://127.0.0.1:3035/
    
      RewriteEngine on
      RewriteCond %{SERVER_NAME} =$SUBDOMAIN
      RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
    </VirtualHost>

replacing $SUBDOMAIN with the subdomain the system should be available under, and $MAILADDRESS with the e-mail address of your administrator. Then symlink it to sites-enabled e.g. by using ln -s /etc/apache2/sites-available/akplanning.conf /etc/apache2/sites-enabled/akplanning.conf.

1. restart Apache sudo systemctl restart apache2.service
2. create a dedicated user, e.g. adduser django
3. transfer ownership of the folder to the new user chown -R django:django /srv/WannaDB
4. change to the new user sudo su django
5. change into the Django project folder cd WannaDB
6. start uwsgi using the configuration file uwsgi --ini uwsgi-akplanning.ini
7. 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.
