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

X 1. Define a model with validations for Song.

X 2. Define all RESTful routes for songs.

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

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

X 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.
