Adding content from one controller to another controller's index - ruby-on-rails

Question

My goal is for users to add individual games pulled from an API gem (https://github.com/games-directory/api-giantbomb) to their personal library. I want users to be able to browse other people's libraries. I have the games showing up via search along with a show page for each game.
I am running into two problems: can't add games to a user's library and can't view other people's library.
Here is my games controller:
class GamesController < ApplicationController
#search for games
def index
#games = GiantBomb::Search.new().query(params[:query]).resources('game').limit(100).fetch
end
#Shows data for individual games
def show
#game = GiantBomb::Game.detail(params[:id])
end
#Adding and removing games to a user's library
def library
type = params[:type]
#game = GiantBomb::Game
if type == "add"
current_user.library_additions << #game
redirect_to user_library_path, notice: "Game was added to your library"
elsif type == "remove"
current_user.library_additions.delete(#game)
redirect_to root_path, notice: "Game was removed from your library"
else
# Type missing, nothing happens
redirect_to game_path(#game), notice: "Looks like nothing happened. Try once more!"
end
end
private
def game_params
params.require(:game).permit(:name, :search, :query)
end
end
When I try to add a game to my library, I get "Game(#70231217467720) expected, got GiantBomb::Game which is an instance of Class(#70231150447440)". So my #game is incorrect but I am not sure what should be there instead.
Even if I could add the game to my library, I can't view other user's libraries. Here is my current controller.
class LibraryController < ApplicationController
#before_action :authenticate_user!
def index
#library_games = User.library_additions
end
end
I get 'undefined method library_additions' even though it is in the model. If I change User to current_user I can see the page, but that means users can only see their page and not others.
Here are my game, user, and library model:
class Game < ApplicationRecord
has_many :libraries
has_many :added_games, through: :libraries, source: :user
end
class User < ApplicationRecord
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :validatable
has_many :games
has_many :libraries
has_many :library_additions, through: :libraries, source: :game
end
class Library < ApplicationRecord
belongs_to :game
belongs_to :user
end
I made my library a join table for users and games but I am thinking I didn't do it correctly. Here is my schema:
ActiveRecord::Schema.define(version: 2020_11_19_143536) do
# These are extensions that must be enabled in order to support this database
enable_extension "plpgsql"
create_table "games", force: :cascade do |t|
t.string "name"
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.string "search"
end
create_table "libraries", force: :cascade do |t|
t.integer "user_id"
t.integer "game_id"
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
end
create_table "users", force: :cascade do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["email"], name: "index_users_on_email", unique: true
t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
end
Am I missing a migration or do I need the rework the models and controllers?
[edit] Here are my routes, I am getting a pathing error when I try to add a game.
Rails.application.routes.draw do
devise_for :users
resources :games do
member do
put "add", to: "games#library"
put "remove", to: "games#library"
end
end
resources :library, only:[:index]
root to: 'pages#home'
get '/search', to: 'games#search', as: :search
get '/games', to: 'games#index', as: :index
get '/user/:id', to: 'user#show'
get '/user/:id/library', to: 'library#index', as: :user_library
end

Here, the error clearly states it is expecting an instance of Game not GiantBomb::Game, so you have to create one.
#game = Game.new(name: 'some name', other fields ....)
if type == "add"
current_user.library_additions << #game
About the other error you can only call association methods on an instance not on the class itself
def index
# You could get the user'id through params for example
#library_games = User.find(params[:user_id]).library_additions
end
