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 Preference model that will store preferences for the app. It will need to have fields for:
   • Song sort order (e.g. "ASC" or "DESC"). This will be used to control the default sort order on the /songs page.
   • Artist sort order. This will be used to control the default sort order on the /artists page.
   • Allowing creation of new songs. Used to control the ability to add new songs to the system.
   • Allowing 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.
2. Create a PreferencesController, routes, and views to manage the preferences. Do this under an Admin module to separate it from the standard user functionality. The artists and songs index pages should order by name according to each preference.
3. Update the songs#new and artists#new actions to check that creating new songs or artists is enabled, and redirect to /songs and /artists, respectively, if that preference is disabled.
4. Make sure tests pass.
5. Ride the bull. Feel the flow.
