Join Kevin Skoglund for an in-depth discussion in this video Read action: List, part of Ruby on Rails 3 Essential Training.
In this movie, we will learn to implement the read actions that make up the…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: list and show.…List displays the listing of a set records, while show displays only a single…record or a detailed view.…The two actions aren't quite as tightly coupled as the actions in create,…update, and delete, where you have displaying the form followed by processing…the form, but they do work together.…It's a very common design to display a list of items to the user and then…the user clicks a link or a button next to one of the items and goes to a…detail page for that item.…
The user reviews the details and then clicks a back to list link when they're…done 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 that concept from other web sites.…Well, let's see how now we can add the list action to our SubjectsController.…
