Rails Dynamic Request Lab


  • 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


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

Learn about Flatiron School's Mission

With a new take on education that falls somewhere between self-taught prodigy and four-year computer science degree, the Flatiron School promises to turn students with little programming experience into developers.

In the six months since the Manhattan coding school was acquired by WeWork, it has spawned locations in Washington, D.C., Brooklyn, and London. Now, WeWork is opening a fourth Flatiron School location, this time in Houston.

Adam Enbar, Flatiron School's cofounder, believes now is the time to grow. "How the world is changing has impacted working and learning in very similar ways. We think education fundamentally is about one thing: enabling people to pursue a better life."

Learn. Love. Code.
