# ungleich_screening_task

A micro project proposed as a screening task for the [Senior Django Developer](https://ungleich.ch/en-us/cms/jobs-ungleich/) position at [ungleich](https://ungleich.ch/).

## Overview

Per requirements, the project behaves differently depending on the version of the [Internet Protocol](https://en.wikipedia.org/wiki/Internet_Protocol) used to navigate it:

- Via IPv4, it shows a static page saying "Sorry, only reachable by IPv6"
- Via IPv6, it shows a friendly cat picture

To determine which version is used, we examine the visitor’s IP address. This is done in a [middleware](require_ipv6) that responds with an error page to non-IPv6 requests.

If the request goes through, a simple [application](friendly_cat) can be accesses, with a single index view showing a friendly picture of a cat.

## Demo

A live demo of the project is available at: [https://ungleich-screening-task.coox.fr/](https://ungleich-screening-task.coox.fr/).

It is served by [Gunicorn](https://gunicorn.org/) through [Caddy](https://caddyserver.com/).

## Usage

To install and run the project on your own computer, you must ensure that the following prerequisites are fulfilled:

- your operating system [supports IPv6](https://en.wikipedia.org/wiki/Comparison_of_IPv6_support_in_operating_systems)
- you can run [Python](https://www.python.org/) version 3.6 or above (it is recommended to use a [virtual environment](https://docs.python.org/3/tutorial/venv.html)), with:
    - [`pip`](https://pip.pypa.io/)
    - [`setuptools`](https://pypi.org/project/setuptools/)
- you can run the [`make`](https://www.gnu.org/software/make/) command

Proceed to [cloning](https://help.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository) this repository, and navigate to its directory.

Then, execute the following command to install the project’s required modules:

```sh
make install
```

Then, execute the following command to run the project using Django’s built-in web server:

```sh
make run
```

You can then navigate the project at [http://localhost:8000/](http://localhost:8000/).
