Course Description

Latest course update: June 2018 - Added a comprehensive tutorial on how to work with the Rails 5.2 encrypted credentials to securely manage configuration variables such as API and application secret keys.
Through the years I've constantly heard the same question from students: "I can follow a tutorial, but I don't feel confident enough to build apps/features from scratch". This course is my answer to that question. I'm not satisfied in simply teaching you how to build an application, my goal is to teach you to understand how to build professional web applications, not to simply follow a tutorial. This is the most comprehensive course I've ever put together and combines my 14+ years of development experience.

I took a completely different approach in building this course. This course is unique for a number of reasons:
  • Curriculum - After completing the initial course outline I sent it out to a group of CTOs and Senior Rails developers from around the world. I asked them to go through the list of features and add the full set of skills they look for when hiring Rails devs. The course outline literally doubled based on their input. So the features that we're going to build throughout this course aren't simply my idea of what it takes to build progressional grade Rails applications, it's the combined knowledge over over a dozen premier developers from a wide variety of industries. One of the hiring managers who reviewed the outline responded to the outline and said, "If you send me developers who build this full set of features, I'll hire them on the spot!".
  • Deep Dives - Going through tutorials is great. However, many times courses that simply walk through the build out of a project skip over important concepts. For this reasons I have created a Deep Dive at the end of each section of this course. These guides select the most challenging topics of each section and give a detailed walk through of the concept so that you can completely understand how to work with the key features of the Rails framework.
  • Full Stack - Many courses promise to teach you how to become a full stack developer, but most of them simply gloss over the concepts that you need in order to build truly professional applications. This course was built to walk you through a real world approach to full stack coding. This includes: backend development with Ruby on Rails, front end coding with HTML/CSS/JavaScript/jQuery, along with advanced ways to use SQL for database management.
  • Immersive - This is not a light and easy course that you can go through in a weekend. This course was designed specifically for coding bootcamp students that have the goal of becoming professional developers. This means that there is over 35 hours of video lessons and you will build a professional grade Rails application by the time you have completed the course.
So with all that being said, let's talk about everything that we're going to build throughout the guides. We're going to build a feature rich portfolio application that you can actually use for your own portfolio (I'm even using it for my own portfolio). Let's walk through the full feature set of what the application will include:
  • Building out a professional Rails environment (if you're on a PC I even built a free C9 dashboard that you can use for this course).
  • We'll utilize Pivotal tracker to follow SCRUM project management best practices throughout the build of this application, just like you'll do in a professional dev shop.
  • Examine how to work with Rails generators, including how to customize the generators so that you can have your very own scaffolds.
  • Work with data flow in Rails. One of my strongest beliefs is that if you can understand how data flow works in Rails, you can build anything! With that in mind we'll take a step by step approach for understanding how data comes into a Rails app and how you can build features that utilize the process.
  • Manage a database. You'll learn advanced SQL techniques for working with data in a Rails application, including how to manage data relationships between tables along with what it takes to implement efficient queries.
  • Best practices. Writing clean code is one of the key requirements of professional Rails developers, throughout the course we'll walk through what professional grade code looks like and the common patterns you'll need to know in order to build well written applications.
  • JavaScript and jQuery components. One of the hallmarks of a modern Rails application is the proper integration of JavaScript features. Throughout the course we'll walk through advanced JavaScript features such as how to integrate drag and drop functionality for users and how to build dynamic forms that change based on user input, all without a page refresh!
  • Streaming Live Data/Page Updates with ActionCable. The top new feature in Rails 5 was definitely Action Cable, which allows for Rails to utilize web sockets and have live page updates. In this course we'll build a real time commenting feature for our portfolio that will showcase your JavaScript skills to everyone who visits your new site.
  • API Integration. Because most modern applications need to communicate with the outside world, in this course we'll build an integration with the Twitter API to pull in real time tweets into our portfolio application.
  • RubyGem Libraries. In addition to teaching you about how to use RubyGems in a Rails application, I also show you how to create your very own RubyGem from scratch and walk through how to use it in your application.
  • In addition to all of these features, we'll also examine: advanced forms, how to integrate professional styles by leveraging Bootstrap 4, building a connection to AWS for file uploads, and how to deploy our application to the web.
In addition to the lectures, I also include the source code for each guide so that you can always have access to the full codebase for the application.
I look forward to going through this immersive program with you and good luck with the coding!Who this course is for:
  • This course is for someone who wants to learn how to build professional grade Ruby on Rails applications
  • This course is for developers that want to learn advanced features specific to the Ruby on Rails version 5 framework, such as ActionCable

Excellent course. Very informative and paced well to maximise the learning you can achieve. I've progressed from a Rails rookie that barely understood the what and why of Rails, to someone who can comfortably work on pre-existing Rails applications, as well as build my own from scratch.You'll notice your improvements early on and if you're someone that works on Rails applications, you'll start attempting to do more as your confidence grows significantly thanks to the way Jordan has created the course.

What an amazing course and teacher! The content of the course is well thought through with a well defined structure, with each lecture smoothly leading into the next. The way Jordan talks about the concepts and the code, shows his passion and it makes me want to learn from him as each step seems just as exciting as the previous. I can't recommend this course enough if you are a new rails developer or just wanting to reinforce your existing knowledge. The response time on the Q&A is great in comparison to other udemy instructors. Any problems in the code due to being outdated is clearly and easily fixable from responses in the current lecture Q&A's. I can't wait for the rails 6 version to come out as I'll be going through all the too! In comparison to every other course I've taken on udemy - not just ruby on rails, Jordan is the best instructor and the course structure is organised and relevant!

A very good course for learning Rails development. The instructor replies quickly to all your questions and suggestions.

I just finished this course, and it was perfect, i learned a lot of things. I really recomended

I'm pasting my conclusion at the top so it can help those thinking of taking this course. Read on if you want to know my reasoning.Conclusion: Skip this course unless you already have a strong familiarity with how Rails works, how MVC systems work, how to write migrations, routes, models, controllers, and auth from scratch. If you don't- take the Odin Project's RoR course first, or another comprehensive resource, then come back here to brush up on your skills. You should also understand how to write web pages with basic html and css. Jordan is an excellent teacher so if you already know Rails this is a great review of fast web app creation with a heavy reliance on outside libraries/gems.Reasoning:So full disclosure, I am still only about 70% done with this course. I was planning on waiting until I finish to write a review but have run into a couple of problems recently that I thought it might be helpful to reveal to prospective students for this Udemy course before I moved on and forgot.I am currently on the Javascript portion of this course and have been held up because in the second guide, Jordan asks us to reference the Github page for a JS library called Sortable. It is not intuitive how to follow along here because the github repo Jordan uses for the course has been changed substantially since he originally created this course 4 years ago. For one, most of the JS files he references in the guide are now TS (typescript) files, also- the directory structure and filenames have all changed, and so have the files themselves, so much so that I'm not sure what file to bring into my project to follow along. I might be able to figure it out, or I might just skim this section because I don't particularly care about implementing drag and drop functionality enough to troubleshoot this, but this problem of the course relying on outdated material and libraries has occurred a number of times and I had to mention it. If you're not a very experienced programmer or are coming from a totally different type of development (mostly Swift in my case), this kind of thing can be really annoying.TL;DR - this course depends on a lot of libraries and code that were written before 2015 and given that it is nearly 2020 now by trying to follow along you are committing to a lot of time spent troubleshooting.The second thing I've been dying to mention about this course is that while I feel I am getting a good introduction to how to build a certain type of application in Rails- a blog and portfolio app- there is not enough repetition to be able to turn around and build other kinds of applications on request. For a course that claims to make you "professional developer" ready- I think this is a serious setback that is a bit dishonest.Abstract discussion of principles via a lecture format to understand how Rails works more broadly and then using code-along style teaching to give examples would be needed to understand what is going on with Rails in most cases, and this is not done. Instead, 99% of the course is code-along style teaching and the last one or two portions of each section are "deep dives" meant to help you understand what we just did for our blog/portfolio app. But after a 15 minute deep dive, you won't really understand what the Rails asset pipeline is and how it works throughout the application, or what the routes.rb file does in terms of MVC, or why we should write logic in the model but not the controller and what the controller actually does, etc.Relatedly, although we use useful libraries like Devise for authentication and Petergate for authorization, to be a job-ready Rails developer you would really need to do these from scratch without the libraries, and apply it to a number of application types, which this course will in no way prepare you to do. Authentication is a really tough subject when you're first learning Rails and it is crucial to be able to understand it. I took this course in part because I thought it would help me review auth but instead we use the Devise library and totally skip this concept.Amusingly enough, if you actually check the Devise github page Jordan links us to- they actually say in the documentation NOT TO USE DEVISE if you don't already know authentication. This is because it's such an important topic and is so universal to web apps- you really shouldn't skip it- but Jordan has. This is really irresponsible- it is kind of like learning to drive your dad's automatic Toyota Prius around the block in preparation for driving a stick shift semi truck cross-country. Here is the quote from the Devise docs:"If you are building your first Rails application, we recommend you do not use Devise. Devise requires a good understanding of the Rails Framework. In such cases, we advise you to start a simple authentication system from scratch... Once you have solidified your understanding of Rails and authentication mechanisms, we assure you Devise will be very pleasant to work with." So while libraries like Devise allow us to skip important concepts and code this app faster, this will decidedly take you steps in the wrong direction for being job-ready.TL;DR - Jordan takes shortcuts that an experienced developer will appreciate but that someone new to Rails will be disadvantaged by following. If at the end of a course that promises to make you a "professional developer" you don't know how to write auth, the course lied. This is dishonest.Lastly, I had beginning familiarity with Rails before taking this course- creating migrations and writing them from scratch, writing custom routes in routes.rb, creating models and associations, writing a custom auth system, working a bit with views and partials and creating controllers, and this course was still a bit fast paced for me. I can totally do it- but I think a coder coming from zero experience would not gain as much from this course as someone who starts by learning HTML, CSS, and Javascript from the ground up and getting reasonably good at them. Jordan actually mentions this in the course- that you should take his basic web dev course before doing this- but it isn't explicitly noted in the course notes when students are thinking of signing up.Working with ERB (embedded Ruby) to write html and css in our views is really different from writing raw web pages with those technologies and would be kind of ridiculous to learn all at once, in my opinion. Conclusion: DO NOT TAKE THIS COURSE IF YOU AREN'T FIRST FAMILIAR WITH HTML AND CSS AND CAN WRITE WEB PAGES WITH THOSE TECHNOLOGIES. There's enough info in here that you can get by without it, but not comfortably, and while you might be able to make the app Jordan makes by following along line by line, you won't know how the heck you did it or how to write other rails applications' views.I am two-thirds of the way through this course, which means I have covered most of the setup for our Rails application. By now I thought I'd know how to turn around and make my own blog and portfolio site from scratch, but I don't. We have only been provided enough info to basically make apps exactly as Jordan has, from using Devise for auth to Bootstrap for the front end, not to mention using generators for most of the hook ups for our actual Rails framework and scaffolds- you really won't know how to create a Rails app from scratch after taking this course.I give the course 3.5 stars because (1) if you already have a good working knowledge of HTML, CSS, Ruby, and Rails this course does a pretty good job teaching you some fast ways to make common types of apps. It is the kind of course that would serve you well if you were already a Rails developer looking to brush on your existing knowledge before getting back on the interview circuit or knew the technology but needed some extra practice. And (2) I also rate the course positively because Jordan is really responsive when you write questions in the Q&A. For a course that is 4 years old that is really impressive, and he does an exceptional job helping his students as follow along- really, kudos for this.All of that said, if you are looking for an intro to Rails with no experience, this course is NOT going to give it to you. There are too many shortcuts, it depends on too many libraries, and the material is too old to ensure a total beginner isn't going to get lost. I know this as someone who has taught himself to code in other languages using online resources- if you are BRAND NEW to Rails or web dev, take Rob Percival's course, or better yet- take the Odin Project's free full stack coding course that includes Ruby on Rails, then take Rob Percival's course to understand how to generally write different kinds of Rails apps, then when you are done, a course like this will provide a nice cherry on top. At that point, you might be ready for an interview.

The course was comprehensive and the instructor imparted his wisdom, which is very helpful. The instructor was also quick to reply to questions. :)It would be nice if the course had upfront notes about taking the course with Rails 6 as the course was developed with an early version of Rails 5. There were occasions where the code examples didn't work correctly which turned out to be a little frustrating and time consuming to get resolved. taking away from the learning experience.

Rails may not be the future but this course helped me understand web development starting from no knowledge and has helped me grow immensely as a developer.

I'm already a professional developer, but I hadn't previously worked with Rails. This course is absolutely comprehensive, and I'm already creating my own web sites.

This course in awesome because of the content and the instructor. You'll learn a bunch of things about Ruby on Rails and development best practices.

I've been working with Rails off and on since 2005. Recent upheaval at my current job has me boning up on the weak points in my skills set to improve my marketability. I was familiar with a lot of the material presented in these videos, but I learned a lot too. Hudgens does a thorough job of explaining things in an easy to understand manner. Equally importantly, he describes how he would solve a problem and then demontrates the process in the videos. This is more useful than you might think. If you're looking to up your Rails game, Hudgens delivers.Another thing is that Hudgens, unlike some of the other authors out there on Udemy, replies back to his students and usually replied to questions or comments I had within 24 hours.I only have two regrets about this course: 1) I didn't dig into this sooner 2) Hudgens doesn't have a larger catalog of courses like this covering other aspects of the Rails ecoverse although he does have a few.

An outstanding amount of Rails knowledge here. Feels like you're being mentored by a senior dev who really cares about giving you all the information he can about the technology. If you're a Rails developer wanting to get beyond the basics, you need this course.

Course was good. Great detail presented. Only complaint is that is was pretty dated (which happens pretty fast these days) and I needed to upgrade a couple of times to keep things working. Other than that, I enjoyed the course.
