Ruby on Rails - Passing Parameters between methods - ruby-on-rails

Question

Routes File:
resources :tournaments do
resources :game, :only => [:new, :index, :create, :update, :destroy]
end
Rake Routes shows:
new_tournament_game GET /tournaments/:tournament_id/game/new(.:format) game#new
I call:
<td><%= link_to 'Add Game', new_tournament_game_path(tournament) %></td>
Game Model:
Takes me to the view game view with the URL:
http:// local host:3000/tournaments/2/game/new
And view:
<h1>New Game in <%= #tournament.name %> Tournament</h1>
<fieldset>
<%= form_for [:tournament, #game], :url => tournament_game_index_path do |f| %>
<table>
<td>
.... More fields .....
</td>
<div class="form-actions">
<%= f.submit "Create %>
</div>
<% end %>
When create is clicked it yields the error:
undefined method `game_url' for #<GamesController:0xb6131e40>
Questions:
Should I be using nested routes or hidden fields?
Do I need a separate tournament_game controller / view to handle the tournament game calls?
How do I get it to look for the correct create route when clicking the Create button?
When I want to have a relationship between two tables, do I only need the nested resource and the has_many / belongs_to calls or do I still need a foreign key column such as Tournament?
Sorry for all of the questions in one thread. Any help you can offer would be greatly appreciated!
Thank you.
Edit:
The error references line 39 which would be the line for the create controller.

Try this:
<%= form_for #game, :url => tournament_games_path(#tournament) do |f| %>
This will call the create method of games controller
Game Controller:
def create
#tournament = Tournament.find(params[:tournament_id])
#game = #tournament.games.build(params[:game])
if #game.save
flash[:success] = "Game created successfully"
redirect_to tournaments_path
else
render new_tournament_game_path
end
end
Routes:
resources :tournaments do
resources :games, :only => [:new, :index, :create, :update, :destroy]
end
