Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
Microsoft Windows 7 SP1 as the host OS
A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

Rails 5 and ActionCable

Assumptions: The application already exists. You have two models article.rb and comment.rb. Articles have two attributes, title and text. Comments have two attributes, text and article_id. See these instructions if you need help getting started.

Routes

Assuming that you are nesting your :comments resources inside of :articles, mount ActionCable and make sure you have a root.

config/routes.rb

Rails.application.routes.draw do

	/*
	ERB template chunk from The Feed's display of emails:

	<section class="postings postings--feed-style" id="postings"
	data-controller="pagination" data-pagination-root-margin-value="40px">
	<%= render partial: "postings/snippet", collection: @page.records, as: :posting, cached: true %>

	<%= link_to(spinner_tag, url_for(page: @page.next_param),
	class: "pagination-link", data: { pagination_target: "nextPageLink", preload: @page.first? }) unless @page.last? %>
	</section>

	For each Ruby module/class, we have Ruby methods on the left and the equivalent
	Clojure functions and/or relevant notes are on the right.

	For clojure functions, symbols indicate existing method definitions, in the
	clojure namespace if none is explicitly given. clojure.contrib./ functions can
	be obtained from http://github.com/kevinoneill/clojure-contrib/tree/master,
	ruby-to-clojure./ functions can be obtained from the source files in this
	gist.

	If no method symbol is given, we use the following notation:

	# see http://stackoverflow.com/questions/5880962/how-to-destroy-jobs-enqueued-by-resque-workers - old version
	# see https://github.com/defunkt/resque/issues/49
	# see http://redis.io/commands - new commands

	namespace :resque do
	desc "Clear pending tasks"
	task :clear => :environment do
	queues = Resque.queues
	queues.each do \|queue_name\|
	puts "Clearing #{queue_name}..."
