To teach you Ruby on Rails we are going to use a "Real World"
example. You've decided to create a voting system for you and your
friends to play with. You've decided at a minimum, you'd like to
allow users to:
* view the topics sorted by number of votes
* vote on topics
* create, edit, and destroy topics
You've sketched up an initial screenshot of what you want it to look like:
![Browser window with topic titles that can be voted on, ordered by number of votes](img/finished_app.png)
When you have completed today's goal of getting the basic
application online you should understand:
* Basic Ruby syntax
* How to try your Ruby code (IRB)
* How to go from requirements to a new working Rails application
* How to get your application online
* The basic tools a RoR (Ruby on Rails) developer uses (source control, editor, console, local server)
* 1-ish hour of Ruby
* 4-ish hours of Rails, broken up in 1-ish hour steps
This is just a rough guideline, not a mandate. Some steps you'll go
over and some you'll go under. It'll all work out by the end of the
We're going to be working with:
* Ruby 2.3 or greater installed via RVM (Mac or Linux), RailsInstaller (Windows), or Docker
* Rails 5.0.x
* SQLite (or PostgreSQL if you installed Docker)
* The text editor of your choice
Everything should be set up the night before during our
install-fest. Please ensure you have everything working _before_ you
show up for RailsBridge on Saturday.
You can verify that you have everything working by trying this out in your terminal:
option "Without Docker" do
>> 1 + 2
option "With Docker" do
$ docker run -it --rm ruby:2.5.1-slim
>> 1 + 2
message "If you can do that, you are probably good to go."
Each lesson will look like this:
<div style="background: white; border: 1px solid black; padding-left: 4em;">
<h1 class="doc_title" style="margin-top: 0em;">Step Title</h1>
<p>Description of the current step.
<p>Red because big goals are important.
<pre class="term">steps to take.</pre>
1 + 1
<p>Yellow because we've gotten it done, but we're not sure yet what's going on.
<p>Details of what the steps actually did, explaining the cause and effect.
<p>Green because we can tie everything together now.
