Rails - Form_tag for custom action

Question

I have a controller games and a method:

def index

@games = Game.all

end

def set_game

@current_game = Game.find(params[:set_game])

end

In my view I have:

<%= form_tag("/games") do %>
<% @games.each do |g| %>
<%= radio_button_tag(:game_id, g.id) %>
<%= label_tag(:game_name, g.name) %><br>
<% end %>
<%= submit_tag "Confirm" %>
<% end %>

Routes:

  resources :games

  match 'games', :to => 'game#index'

How can I make this form work for my set_game method?

Thanks.

Answer 1

<%= form_tag(set_game_games_path) do %>
 ...
<% end %>

#routes.rb
resources :games do
  collection do
    get '/set_game', :as => :set_game
  end
end
