How this Course Will Work

Welcome to Rails! Maybe you've skipped right here because you just want to start building websites or maybe you made it through the Ruby course and have a great base to work from. Either way, we're about to have some fun.

You should already have a good idea of what Rails is all about after covering it in previous lessons (see Prerequisites below for links). At this point, it's time to take that theoretical knowledge and start building websites. This portion of the curriculum will be the most build-heavy so far. You will still be asked to read docs, check out blog posts, and watch videos before building, of course, but projects will be the major focus.

After each lesson or two, you'll be asked to build one or more independent projects utilizing the concepts that were just covered (which is exactly what we've been doing up until now). You'll also be asked to complete a chapter or two from the Ruby on Rails Tutorial by Michael Hartl.

That tutorial is often too deep for fresh beginners to Rails but we'll be using it as a way to build a single large project one chapter at a time while you progress through the lessons. You should have a much better idea of what's going on in the tutorial than your average beginner since we'll be covering each of its component concepts prior to actually building it in the tutorial.

The Roadmap

We'll be starting with an overview of important topics like HTTP, MVC, REST, APIs, Cookies and Authentication for some context before moving into the really fun stuff.

We'll move front-to-back, starting with the routing layer and moving into controllers and views so you can build a functional (if not yet pretty) interface for your data. Next you'll learn about storing and finding data in databases with SQL then how to turn that SQL into Active Record queries. We next cover web forms, an area that has a lot more going on behind the scenes than you might expect, and authentication, which is essential to securing your application. We'll cover some other intermediate topics like state and the asset pipeline to round out your initial understanding of Rails.

But we can't stop there, so we'll get back into ActiveRecord to give you the tools to really make your data dance, as well as the knowledge of the forms that is required to bring that advanced functionality to the User. This is the really important side of Rails, so we'll spend a good bit of time working with it.

Finally, we'll cover additional useful topics like how to send emails from your application, building and interfacing with APIs, design patterns, metaprogramming and advanced routing before having you build your final project.

Our Tools and Texts

The most important resources that we'll leverage are the Rails Guides and the Ruby on Rails Tutorial. Together, they comprise a near-complete set of open-source resources for learning Rails.

The Guides are comprehensive, basically a completely open-source textbook and reference manual for Rails. At times they'll get a bit more technical than you might like, and it may be okay to skim some of that. When you Google for a solution later, if it's not showing up on Stack Overflow then it's probably going to give you a link to the Guides.

The Ruby on Rails Tutorial (aka the Hartl Tutorial, after its author) is another free resource which builds (over several hundred pages) a full featured web application (Twitter clone), including introducing you to testing your code using RSpec along the way.

My typical workflow for a long time went sort of like this:

  1. I know I want to implement a feature... Google search to see if anyone implemented the same feature. Land on a Stack Overflow post that describes how to implement a similar feature.
  2. The SO post shows me the right direction to take, so I Google for the specific method it mentioned that I don't understand. I end up on the Rails Guides page that talks about it.
  3. I pull up my completed version of the Rails Tutorial to make sure I've got the syntax correct and possibly to help write tests while I implement the feature.

As you can see, I frequently relied on the main resources you'll be learning from and you'll find them to be helpful long after you've completed this course, so it makes sense to get familiar with them!
