CRUD With Validations Lab

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

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

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

6. Be sure to include your new assets in application.html.erb

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

8. Set the root route to the song index.

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