Introduction to Active Record

In this module, we will begin exploring the database-interaction portion of Rails. We will start off with migrations that enable you to create and modify the schema of the database. We will then move on to discussing the Active Record gem Rails uses, which enables you to create, retrieve, update, and delete the data from the database. Before looking at Active Record, we will talk about some advanced Ruby features of meta-programming that will help facilitate our Active Record journey.

Security and Nested Resources in Action Pack

In this module, we will talk about how to deal with nested resources in Rails. We will then talk about securing your app with a username and password combination for authentication purposes and making sure that users are only authorized to make changes to and view their own resources. We will finish off the module by discussing pagination and deploying to Heroku Paas (Platform as a Service).

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!

대학: NLDec 17th 2015

Great explanation of not so easy to understand concepts. Lecturer provides good example that can help material better and see how what you've learned can be applied to real world scenarios.
