RESTful Routes

In this lab you will walk through how to build each element required to render a list of students out in the browser. The RSpec/Capybara tests for this lab can be found in spec/features, both tests should be passing to complete the lab.

Instructions

• Create a route that is mapped to a students' controller index action, the resulting route should be /students

• Create a controller for students and have it inherit from ApplicationController

• Integrate a controller action in the students' controller for handling the index action

• Have the new index action call the Student model and pull in a list of all of the students with Student.all and store it in an instance variable

• Map an index.html.erb view file to the student controller and iterate over the list of students returned from the index action in the controller
