Course description

To begin this course we will cover how the model view controller design pattern works in the Ruby on Rails framework, specifically discussing the rolls and best practices associated with each element. We will walk through the file system so you can become familiar with items such as the respective roles of our config directory, how the asset management sytem is structured, plus many other items, and lastly, how we utilize the Gemfile. The Ruby on Rails development stack works very closely with version control management systems such as Github and we will cover what Git is, why it is important and how to implement it into our application. Routing is one of the core fundamentals of any web application, and we will walk through how to setup a root homepage. We will finish up this course by building a scaffold into our application that interacts with our database, has form elements for the user, renders a database query on the page and is tested using RSpec.


This course teaches anyone who is interested in learning the basics of programming computers using Ruby on Rails.
