課程概述

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....

A nice continuation to course 1 of this specialization, deeper dive into RoR, among other things you will learn how to manipulate/display database data and how to authenticate/authorize users!

Great program. Well structured, with lots of additional resources that make for easier self-study. Videos are just the right length to provide the knowledge without being too long and too filled with details. All in all, this is an excellent 2nd course in my Ruby on Rails Web Development skills development.

The course assignments is hard and takes lots of hours but are valuable to me as it systematically consolidates rails' components for me.

The first two courses in this series have really rekindled my interest in software development after many years away from it. Kalman does a great job - the lectures are interesting and the assignments are challenging.

I really liked writing the authentication myself. I've relied on Devise (and will continue using it mostly) but really got an appreciation for what was going on.
