# RESTful Index Action Lab

## Objectives

1. Draw a get route
2. Map a route to a controller action
3. Define a controller action
4. Load instances from ActiveRecord into a controller instance variable
5. Render a template
6. Use an instance variable from a controller action in a template
7. Iterate over an ActiveRecord collection in ERB
8. Build a classical index action/view

## 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

* Run `bundle install` from your terminal
* Create a controller for students and have it inherit from ApplicationController
* Create a route for the path `/students` that maps to a StudentsController "index" action.
* Add a controller action to the StudentsController named `index`
* Have the new `index` action pull in a list of all of the students with `Student.all` and store it in an instance variable
* Create an `index.html.erb` view file and render it from your `Students#index` action. The `index.html.erb` file should be placed within a `views/students` folder.
* In your view, iterate over the list of students returned from the index action in the controller and display the appropriate information.

## Resources

* If you run into an ActiveRecord::PendingMigration error when you run the tests, try `rake db:migrate RAILS_ENV=test` in the terminal then run the tests again
