Flexing Associations in Rails

Objectives

• Be comfortable building and associating objects via all mechanisms available

Instructions

1. Create 3 models: Artist, Album, and Song

2. The artist, "Wu-Tang Clan", has the following album, with the following songs:

   • "36 Chambers"
     1. "Bring da Ruckus"
     2. "C.R.E.A.M"
     3. "Protect Yo Neck"
     4. "Method Man"

Add each song to the album in a different way. e.g. using an example where an Author has many Posts: Post.build, posts << Post.new, Author.build_post

3. The artist, "Notorius B.I.G.", has the following albums, with the following songs.

   • "Ready to Die"

     1. "Gimme the Loot"

   • "Born Again"

     1. "Dead Wrong"

   • "Life After Death"

     1. "Hypnotize"

Add the albums through a song, and add artists through album, via .build_*, push (shovel <<), or assignment.

FYI under Wu Tang Clan, "Protect Yo Neck" should be "Protect Ya Neck". Consider this my pull request :)

I'm pretty sure the Author/Post example is reversed, should be Post.build_author and the first is not clear, should be author.posts.build

Here's the doc that helped me:
