Need help seeding in rails

I am very new to rails and need help with seeding my tables. I have two tables "tracks" and "genres" and their migration files look like this 

class CreateGenre < ActiveRecord::Migration[5.1]
  def change
    create_table :genres do |t|
      t.string :rock
      t.string :rap
      t.string :jazz
      t.string :alternative
      t.references :track, foreign_key: true

      t.timestamps
    end
  end
end

class CreateTracks < ActiveRecord::Migration[5.1]
  def change
    create_table :tracks do |t|
      t.string :trackname
      t.string :artist

      t.timestamps
    end
  end
end

And here are the models

class Track < ApplicationRecord
  has_one :genre
end
class Genre < ApplicationRecord
  belongs_to :Track
end

Right now when I go to psql and check my tracks table, it has two columns trackname and artist. And I want to add genres for the tracks too but i dont know how to do it?

I did this 

data = [
  {
trackname: "hell yes",
artist: "beck"
    },
   {
trackname: "jailhouse rock",
artist: "elvis presley"
    }
]

I am having problem figuring out how to seed the genre too when i am doing this. Where would i put it? please help.

Sounds like you want to add genre to your Tracks table by running a migration.

Run: 

rails generate migration add_column_to_tracks genre:string

Then run rake db:migrate.

That should add the new field to the database.

From what I understand from your code I would try the following:

Track.create!(
  trackname: "hell yes",
  artist: "beck",
  genre_attributes: {
    rock: "true"
  }
)
