Namespaced Routes Lab

Objectives

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

Overview

We're going to add some administrator functions to our song library and use what we learned about namespaced routes and module scope to organize our routes and controllers.

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 model called Preference with two string fields: song_sort_order and artist_sort_order and two boolean fields: allow_create_artists and allow_create_songs.
  2. Implement a SettingsController under an Admin module with index and update actions. It will be responsible for maintaining two preference entries named song_sort_order and artist_sort_order. There should only be one record for each so try first_or_create to create an @preference in the controller. The default value for each sort preference should be "DESC". Redirect to settings#index after update.
  • Hint: Because Rails doesn't know how to "count" Settings, the helper for the index route will be different than you're used to. Instead of admin_settings_path going to /admin/settings, you'll need to use admin_settings_index_path. Make sure to run rake routes to verify your URL helper names.
  1. Implement routes and views for the SettingsController. Use radio buttons for the values. Acceptable values are "ASC" and "DESC". Both preferences should be editable from the index view whether new or existing.
  2. Update the artists#index action to order by name with artist_sort_order and the songs#index action to order songs by title with song_sort_order. Make sure to check that the value exists and set it to the default if it doesn't.
  3. Implement an AccessController under the Admin module with index and update actions. It will be responsible for maintaining two preference entries named allow_create_artists and allow_create_songs. As with the SettingsController, use first_or_create to ensure we only have one preference. The default values for allow_create_songs and allow_create_artists should be true. Redirect to access#index after update.
  4. Implement routes and views to manipulate for the AccessController. Use radio buttons for the values. Acceptable values are "true" and "false". Follow the same guidelines as for SettingsController views in step 3.
  • Note: We will have the same URL helper change here as we do for SettingsController, so check your rake routes to ensure you use the right helpers.
  1. Update the songs#new and artists#new actions to check the access control preferences and redirect to /songs and /artists, respectively, if creation is disabled.
  2. Make sure tests pass.
  3. Ride the bull. Feel the flow.
