Rails with Active Record and Action Pack
Heads up! This course may be archived and/or unavailable.
Ruby on Rails Web Development,
You already know how to build a basic web application with the Ruby on Rails framework. Perhaps, you have even taken Course 1, "Ruby on Rails: An Introduction" (we highly recommend it) where you relied on external web services to be your “data layer”. But in the back of your mind, you always knew that there would come a time when you would need to roll up your sleeves and learn SQL to be able to interact with your own relational database (RDBMS). But there is an easier way to get started with SQL using the Active Record Object/Relational (ORM) framework. In this course, we will be able to use the Ruby language and the Active Record ORM framework to automate interactions with the database to quickly build the application we want. In Rails with Active Record and Action Pack, we will explore how to interact with relational databases by using Active Record, a Ruby gem, which Rails uses by default for database access. We will then take a look at what role Active Record plays in the overall request-response cycle, when a client (the browser) requests data from the server, as well as how to submit the data to the server. Of course, when accessing data, security is of paramount importance! We will talk about vulnerabilities such as SQL injection, as well as how to secure access to data by authenticating and authorizing users accessing the data. Take this course to build a Ruby on Rails application with Active Record to automate the detailed SQL interactions with our database.

All in all, this is an excellent 2nd course in my Ruby on Rails Web Development skills development.
As someone new to ruby on rails, I found some details were glossed over, and some explanations were vague.
I had to move "ENV['RAILS_ENV'] ||= 'test'" from rails_helper.rb to spec_helper.rb to get stuff working.Without my ruby on rails hubby, I'd have been lost!
This course is awesome, even to who know a little about Ruby on Rails.
In this course I got new skills about the Ruby on Rails framework using the incredible Active Record ORM and the Action Pack.

some things
Because the assignments are written in this way, some things will break but are fixed in later steps, though you will not know that they are fixed later after you spend time trying to fix the issues so RSPEC or the Web test will pass.
You will still have to use Google to figure out what the correct convention is and maybe why some things are done.
I was already familiar with the concepts taught in this course but I still learned some things which is nice.

much better
The RSPEC files are much better at actually pointing you towards what your issues are.
may be not the one for a beginner but help to gain some basics Could have been much better ....should have been a proper video tutorial very useful Great follow up course on Ruby programming!
at times
They can be very confusing at times, hard to follow.
It has some weird conventions and tries to be "Too helpful" at times.
