Here are the essential parts of this project's file structure. The first, dceu2019/ contains a Django project and hugo_site/ contains the Hugo project for static site generation (the main site):

We use a static main site because we want to archive the main conference website as easily as possible. We are using the default version of Hugo for Ubuntu 18.04, so to generate and run the main site, just do:

# Install Hugo
$ sudo apt install hugo

# Go to project directory
$ cd hugo_site

# Run dev server
$ hugo server

The Django project will be used before and during the conference for planning purposes: Talk submissions, scheduling, and ticket holder services such as ride sharing and accommodation sharing.

You can install and work on a development version following these steps:

# Create a Python 3.6+ virtualenv (virtualenvwrapper)
$ mkvirtualenv -p python3

# Install project & dependencies in "editable" mode (-e), with the [dev]
# dependency subset.
# You should repeat this command when you pull in new changes which can
# contain new requirements or version upgrades
$ pip install -e "dceu2019[dev]"

# Try invoking the Django main management script
$ python dceu2019/manage.py

# ...you will be told that it has created a local.py file. You might want to
# edit this now or later depending on your needs.

# When ready, run migrations.
$ python dceu2019/manage.py migrate

# Initialize PreTalx: Creates a superuser etc.
$ python dceu2019/manage.py init

# Now you can run the development server
$ python dceu2019/manage.py runserver

# Point your browser to localhost:8000/ and you'll see an empty schedule
