CRUD With Validations Lab

Introduction

Your goal in this lab is to create a thorough CRUD interface for one model, the Song.

Songs

Songs have the following attributes and limitations:

• title, a string
  • Must not be blank
  • Cannot be repeated by the same artist in the same year
• released, a boolean describing whether the song was ever officially released
  • Must be true or false
• release_year, an integer
  • Optional if released is false
  • Must not be blank if released is true
  • Must be less than or equal to the current year
• artist_name, a string
  • Must not be blank
• genre, a string

Requirements

Use the resource generator, not the scaffold generator

1. Define a model with validations for Song.

2. Define all RESTful routes for songs.

3. Render the list of songs in an HTML table.

4. Build views that connect to each other using route helpers.

5. Use form_for to build forms with pre-fill and error list features. (Hint: Try using a partial to cut down on copy/pasting!)

6. Allow deleting songs with a link, using link_to. Check out the official documentation for additional info including setting the method: to :delete.

7. Use strong parameters in your POST/PATCH controller actions.

8. Set the root route to the song index.
