Sortify - Rails Associations

For this exercise, we'll create a "Sortify" Rails app which stores songs and genres.

Deliverables

Part 1

Create a model for genre with name and description
Create a model for songs with name and genre
The associations are as follows:
- Genre has_many Songs
- Song belongs_to a Genre
Seed your database with your own sample data of songs and genres from a seed file
Implement controllers and views for:
- show all genres /genres/
- show all songs from one genre /genres/:id/songs/

Part 2

Sometimes songs can be classified into more than one genre, therefore we need to modify our app.
Change your song model to just have a name
Create a join table GenresSongs
The revised associations are as follows:
- Genre has_and_belongs_to_many Songs
- Song has_and_belongs_to_many Genres
Seed your database
Use the command line to add a song to a couple of genres
Implement a view such that when showing a specific song, display the song name and the list of genres associated with it.

Further

Implement full CRUD functionality for songs and genres.
Implement nested routes for this app.

Not tired of pokemon yet?

Implement a pokedex app after this json file: https://github.com/wdi-sg/pokedex-express/blob/master/pokedex.json

{
    "id": 1,
    "num": "001",
    "name": "Bulbasaur",
    "img": "http://www.serebii.net/pokemongo/pokemon/001.png",
    "type": [
      "Grass",
      "Poison"
    ],
    "height": "0.71 m",
    "weight": "6.9 kg",
    "candy": "Bulbasaur Candy",
    "candy_count": 25,
    "egg": "2 km",
    "spawn_chance": 0.69,
    "avg_spawns": 69,
    "spawn_time": "20:00",
    "multipliers": [1.58],
    "weaknesses": [
      "Fire",
      "Ice",
      "Flying",
      "Psychic"
    ],
    "next_evolution": [{
      "num": "002",
      "name": "Ivysaur"
    }, {
      "num": "003",
      "name": "Venusaur"
    }]
  }

Start with creating a join table for "types". Pokemon has many types, types has many pokemon.

You could also implement one of the other many-to-many relationships in the JSON file- (e.g. weaknesses, next evolution, etc.)

Further

Implement full CRUD functionality for pokemon and types (or other attribute).
Implement nested routes for this app.
