Rails Dynamic Request Lab

Objectives

• Draw a route with a dynamic variable

• Use a routes variable in params within the logic of an action

• Assign an instance variable in a controller action

• Use a controller instance variable to generate a dynamic ERB template.

• Build a classical show action/view

Instructions

There are three RSpec/Capybara specs in this lesson; you can find them in spec/features/student_spec.rb. Make sure they pass without breaking the other tests. To complete this section, all specs should pass.

In this lab, you will work through the full MVC pattern by building a student management app for The Flatiron School. At a high level, you will integrate the following scenario in your application:

1. The user is able to go to /students/2 to receive information on the student with an id of 2

2. The application should render the values from the student record in the database

Keys to remember

• Make sure that you use a route variable for the show request path

• If you google around and discover generators/scaffolds, don't use them for this lab
