coin

The COIN project

Coin is Illyse's Information System, designed to manage both members and Internet accesses, such as through DSL, VPN, wireless…

It is written in Django, and makes an heavy use of LDAP (for authentication, and to store configuration information).

It features a generic configuration interface, which allows to implement custom backends for different technologies. Currently implemented is a LDAP-based backend for OpenVPN.

Coin currently only works with python2, because python-ldap is (as of 2013) not compatible with python3.

The project page (issue, wiki, etc) is here:

https://www.illyse.org/projects/ils-si/

A mirror of the code is available at:

Demo

A demo of COIN is publicly available at:

This user account has access to the administration interface.

Quickstart

Get yourself a virtualenv. On Debian, install python-virtualenv. On Archlinux, the package is called python2-virtualenv, and you must replace the virtualenv command with virtualenv2 in the following.

To create the virtualenv (the first time):

virtualenv ~/tmp/venv-illyse

To activate the virtualenv (you need to do this each time you work on the project):

. ~/tmp/venv-illyse/bin/activate

Install dependencies. On Debian, you will probably need the python-dev, python-pip, libldap-dev, libpq-dev and libsasl2-dev packages.

sudo apt-get install python-dev python-pip libldap2-dev libpq-dev libsasl2-dev

Then run:

pip install -r requirements.txt

You may experience problems with SSL certificates du to self-signed cert used by code.ffdn.org. You can temporarily disable certificate verification in git : git config --global http.sslVerify false

You should now be able to run python manage.py (within the virtualenv, obviously) without error.

The coin/settings_local.py file is ignored by Git: feel free to override any setting by writing into that file. For example, to override the DEBUG settings:

echo '# -*- coding: utf-8 -*-' > coin/settings_local.py
echo 'DEBUG = TEMPLATE_DEBUG = True' >> coin/settings_local.py

At this point, you should setup your database. Recommended is postgreSQL, but you might be able to use SQLite. For more information, see https://www.illyse.org/projects/ils-si/wiki/Mise_en_place_environnement_de_dev

If you don't want to use LDAP, just set in your settings_local.py:

LDAP_ACTIVATE = False

The first time, you need to create the database, create a superuser, and import some base data to play with:

python manage.py migrate
python manage.py createsuperuser
python manage.py loaddata offers ip_pool

Note that the superuser will be inserted into the LDAP backend exactly in the same way as all other members, so you should use a real account (not just admin/admin).

Then, at each code update, you only need to apply migrations:

python manage.py migrate

At this point, Django should run correctly:

python manage.py runserver

Available commands

Some useful administration commands are available via manage.py.

python manage.py members_email: returns email addresses of all members, one per line. This may be useful to automatically feed a mailing list software. Note that membership is based on the status field of users, not on membership fees. That is, even if a member has forgot to renew his or her membership fee, his or her address will still show up in this list.

python manage.py charge_subscriptions: generate invoices (including a PDF version) for each subscriber. You probably want to run this command every month as a cron task, see below.

python manage.py call_for_membership_fees: send reminder emails to members whose membership fee is about to expire or is already expired (1 month before, on the day of expiration, 1 month after, 2 months after, and 3 months after). You should run this command in a cron job every day.

Configuration

You should first setup the sites application, in the admin. The domain name configured there is used for outgoing emails.

ISP-specific configuration

The main place to customize Coin for your ISP is the IspDatabase application, in the admin. Information entered in this application has two purposes:

1) generate a JSON file usable by http://db.ffdn.org/

2) customize the user interface (postal address, bank account, ISP name & logo...)

Some bits of configuration are done in settings.py: LDAP branches, RSS feeds to display on the home page, and so on.

Cron tasks

You may want to run cron jobs for repetitive tasks.

To generate invoices on the first day of each month, here at 3 am:

0 3 1 * * /home/coin/venv/bin/python manage.py charge_subscriptions

To send reminder emails for membership fee expiration:

42 3 * * * /home/coin/venv/bin/python manage.py call_for_membership_fees
