Namespaced Routes Lab

Objectives

  1. Organize controllers using a module.
  2. Use namespaced routes.

Overview

We're going to add some administrative functions to our song library. Using what we learned about namespaced routes and module scope, we'll organize our controllers and routes under an admin namespace to keep them separate from the regular user functions.

Instructions

The base application has been provided with tests. Make sure to run rake db:seed to set up seed data. Tests can be run with rspec.

Note: Since we're building new features on an existing project that already has tests, part of the job is to make sure the tests that already pass at the beginning still pass when you're done!

  1. Create a migration and a model for a Preference class that will store preferences for the app. In the migration, define boolean fields for:
    • allow_create_songs: Allows for creation of new songs. Used to control the ability to add new songs to the system.
    • allow_create_artists: Allows for creation of new artists. Used to control the ability to add new artists to the system.
    • Note: There will only be 1 instance of Preference, not a preference associated with each artist/song. After creating the model, run rake preferences:load so that your code will work in the browser. This will run the Rake task defined in the lib/tasks/preferences.rake file and save one Preference instance to the database.
  2. Create a PreferencesController, routes, and views. Do this under an Admin module to separate it from the standard user functionality.
  3. Update the songs#new and artists#new actions to check that creating new songs or artists is enabled using the Preference class, and redirect to /songs and /artists, respectively, if that preference is disabled. If the preference is enabled, show the new view instead.
    • Hint: Remember, there will only be one instance of the Preference class saved to the database. When determining if creating songs or artists is enabled, you'll need to find the first instance of the Preference class, and use that instance along with some conditional logic to determine whether to redirect or display the view.
  4. Make sure tests pass.
