Join Kevin Skoglund for an in-depth discussion in this video Read action: Index, part of Ruby on Rails 4 Essential Training.
…In this movie we will learn to implement the index…action which is part of basic CRUD in our controllers.…In the previous movie, we saw that reading records from the…database is usually handled by two standard Rails actions: Index and Show.…Index displays a list of records, while Show…displays a detailed view of a single record.…The two actions work together hand-in-hand as a common application design pattern.…The application displays a list of items to the user.…The user clicks a link for one of those items.…Then the application shows the user a detail page for that item.…
The user reviews the details and then clicks a link to go back to the main list.…Even if you've never put these exact terms to it…before, I'm sure you're familiar with the concept from other websites.…Let's see how we can add the index action to our subjects controller.…So if you don't already have it open, open up your subjects controller.…And in the place holder that it gave us for the index action, we want…to add code to tell the controller to assemble a list of all of the subjects.…
