Fedora Elections

fedora-elections is a web application written in Python and based on Flask. It implements the Range Voting system.

This project was developed using Fedora Project requests but can be easily adapted to other projects. Fedora Elections is integrated with the Fedora Account System (FAS).

Creating a development environment

To work on the Fedora Elections web application, you will need to create a development environment to test your changes. This is simplified by using Vagrant, a powerful and useful tool for creating development environments on your workstation.

Using Vagrant

You can quickly start hacking on the Fedora Elections web application using the Vagrant setup included in the elections repo is super simple.

First, install Vagrant, the vagrant-libvirt plugin, and the vagrant-sshfs plugin from the official Fedora repos:

sudo dnf install vagrant vagrant-libvirt vagrant-sshfs

Now, from the main directory (the one with the Vagrantfile in it), run the vagrant up command to provision your development environment:

vagrant up

When completed, you will be able to SSH into your development virtual machine with vagrant ssh and run the command to start the Fedora Elections server:

vagrant ssh
[vagrant@localhost ~]$ pushd /vagrant/; ./runserver.py --host "";

Once that is running, go to localhost:5005 in your browser to see your running Fedora Elections test instance.

A note about fonts

Fedora Elections uses web fonts hosted in Fedora's infrastructure that might not work when hacking locally due to CORS restrictions. If you install the fonts yourself, the Fedora Elections website will look the same as it would when deployed to production.

You can install the fonts with this command.

sudo dnf install open-sans-fonts

A note about the git branches

You will find different git branches in the git repository of elections, here is a short description of what they are meant for.

Elections originally followed the git flow development model before moving to being deployed in OpenShift using s2i (source to image) in a more continuous deployment model. You will find traces of these different models in the git branches.

  • develop: this is the default branch of the project, the one you are checked out on when you clone the repository. This is the place where all the development happens. Your Pull-Requests should target this branch.
  • master: this is the branch in which develop is merged into when a new release is made. So you will find master the lastest stable release basically.
  • staging: this is the branch from which the staging instance of elections is being deployed. That branch contains a few commits that are not in develop as they relate to making elections be easily deployable in openshift via s2i. These changes are not code related and thus do not need to be present in develop. This branch is rebased on the top of develop and force-pushed when staging is being updated. Your Pull-Request should not target this branch.
  • production: similarly to the staging branch above, this is the branch the production instance of election is being deployed from. Here as well it contains a few extra commits that are related to configuring elections for openshift/s2i, and here as well the branch is rebased, on the top of staging and force-pushed when production is being updated. Your Pull-Request should not target this branch.

How to launch Fedora Elections

The following steps will get the rest of the application running. Make sure to use your Vagrant development environment when following these steps.


Before launching fedora-elections, the following packages should be installed:

  • httpd
  • libxslt
  • python
  • python-backports-ssl_match_hostname
  • python-bunch
  • python-chardet
  • python-fedora
  • python-fedora-flask
  • python-flask
  • python-flask-sqlalchemy
  • python-flask-wtf
  • python-jinja2
  • python-kitchen
  • python-lxml
  • python-openid
  • python-ordereddict
  • python-ordereddict
  • python-setuptools
  • python-simplejson
  • python-six
  • python-sqlalchemy0.7
  • python-urllib3
  • python-wtforms

Get the source code

This project is hosted on Pagure. For convenience, a mirror is also hosted on GitHub.

You can obtain the code via:

git clone https://pagure.io/elections.git

Install pip requirements w/ tox for testing

Set up venv (replacing <base_path_for_venv> and <venv_name>):

pip install --user virtualenv tox
mkvirtualenv <base_path_for_venv>/<venv_name>
. <base_path_for_venv>/<venv_name>

Install requirements:

pip install -r requirements.txt

Configure the application

An example configuration file is provided here.

Register the application using openid-connect

From root of project, run:

oidc-register https://iddev.fedorainfracloud.org/ http://localhost:5005

Create database


python createdb.py

Create a local configuration file


cat > config <<EOL

Starting the app

There are 2 ways to start the application:

  • Without Apache
  • With Apache

Without Apache

This is useful for a quick development instance, when you don't have to worry about security yet. Do not run this in production. The server will start on

./runserver.py -c config

With Apache

Copy fedora-elections.conf to your Apache conf.d directory:

sudo cp files/fedora-elections.conf /etc/httpd/conf.d/.

Next, place fedora-elections.wsgi in /var/www:

sudo cp files/fedora-elections.wsgi /var/www

Adjust the Apache configuration file to point to your web directory. Then, adjust the .wsgi file in /var/www to point to the fedora_elections directory.

Place the configuration file in /etc/fedora-elections/fedora-elections.cfg and adjust it as you wish.

sudo mkdir -p /etc/fedora-elections/
sudo cp files/fedora-elections.cfg /etc/fedora-elections/

Now, restart Apache:

sudo systemctl restart httpd

Running tests

fedora-elections uses tox to simplify testing, and support testing across multiple environments.

Refer to earlier in this section on "How to launch Fedora Elections" in this document to get set up with tox

To run tests, simply run:


How to contribute

As mentioned earlier, this project is primarily hosted on Pagure. There is a mirror on GitHub, but only for convenience. Pagure is the preferred platform for accepting contributions. To file an issue, RFE, or other ticket, you must use Pagure. See other issues already filed here.
