Did you ever want to build a web application? Perhaps you even started down that path in a language like Java or C#, when you realized that there was so much “climbing the mountain” that you had to do? Maybe you have heard about web services being all the rage, but thought they were too complicated to integrate into your web application. Or maybe you wondered how deploying web applications to the cloud works, but there was too much to set up just to get going.

Welcome and Setting Up the Development Environment
In this module, we will install software required to develop Ruby on Rails applications. We will also demonstrate the use of a popular Ruby on Rails editor called “Sublime Text”. We will finish the module by familiarizing ourselves with a version control system called “Git” that will be used later in the course to submit assignments, as well as to deploy Ruby on Rails applications to a PaaS (platform as a service) called “Heroku”.

TOP REVIEWS FROM RUBY ON RAILS: AN INTRODUCTION
by HMSep 30, 2017
I have played around with Ruby on Rails before but this course really helped me understand the nots and bolts. It is worth replicating all the examples shown in the videos to get a good understanding,
by JMJan 21, 2019
I like the content but definitely the submission and assessment should improve. The main problem is the version used in the videos is already quite old and difficult to get that version nowadays
by GCAug 6, 2016
One of the most challenging things I've ever done. The course goes from zero to web deploy in 3 weeks and there are more to enjoy, discover and learn....\n\nTry it, I't's a no-return voyage
by MBMay 1, 2016
Good intro, nice to mix in the various concepts that I will be working with as well (Heroku, Git, etc.). Also appreciated the Java comparisons since I have been working in Java for 15 years.
Frequently Asked Questions
When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
Is financial aid available?
Yes, Coursera provides financial aid to learners who cannot afford the fee. Apply for it by clicking on the Financial Aid link beneath the "Enroll" button on the left. You’ll be prompted to complete an application and will be notified if you are approved. Learn more.
