form_for深层嵌套路线的多个实例

Question

我正在为团队提供一种进入体育比赛的方式。在进入球队时，用户还必须注册全部该球队的球员。我协会&路线是设置如下：

class Tournament < ApplicationRecord 
    has_many :teams 
    has_many :players, :through => :teams 

    accepts_nested_attributes_for :teams 
end 
class Team < ApplicationRecord 
    belongs_to :tournament 
    has_many :players 

    accepts_nested_attributes_for :players 
end 
class Player < ApplicationRecord 
    belongs_to :team 
    has_one :tournament, :through => :team 
end 

（routes.rb中）

resources :tournaments do 
    resources :teams, :only => [:new, :create] do 
     resources :players, :only => [:new, :create] 
    end 
end 

我想有一个窗体，这些都保存与点击多个玩家输入。我的电流控制器& new.html.erb如下：

（players_controller.rb）

class PlayersController < ApplicationController 
    def create 
     @tournament = Tournament.find_by_id params[:tournament_id] 
     @team = Team.find_by_id params[:team_id] 
     @player = @team.players.new(player_params) 
     if @player.save 
      redirect_to root_path #just return home for now 
     else 
      redirect_to new_tournament_team_path(@tournament) 
     end  
    end 

    def new 
     @tournament = Tournament.find_by_id params[:tournament_id] 
     @team = Team.find_by_id params[:team_id] 
     @player = [] 
     3.times do 
      @player << @team.players.new 
     end 
    end 

    private 

    def player_params 
    params.require(:player).permit(:name, :tournament_id, :team_id) 
    end 
end 

（播放器/ new.html.erb）

<%= form_for [@tournament, @team, @player] do |f| %> 
    <% hidden_field_tag :tournament_id, @tournament.id %> 
    <% hidden_field_tag :team_id, @team.id %> 
    <% 3.times do %> 
    <p> 
     <%= f.label :name, "Name: " %> 
     <%= f.text_field :name %> 
    </p> 
    <% end %> 
    <%= submit_tag 'Submit', :class => 'rounded_btn' %> 
</p> 
<% end %> 

从我的理解我应该试图创建一个“球员”阵列，其中将包含输入表单中的3名球员的名字。这个数组然后被创建操作保存。这是否是正确的方式去解决这个问题？为了让我走上正确的道路，可能需要改变我的代码？

感谢。
