Rails嵌套窗體更新與Ajax錯誤

Question

在遊戲中，我有一個10×10的網格與100個正方形，我試圖做一個正方形的按鈕，當點擊更改方塊的user_id到current_user ID。

遊戲/ show.html.erb

<% @squares.each_slice(10) do |slice| %> 
     <% slice.each do |s| %> 
      <%= div_for s, class: 'sq' do %> 
       <%= s.boardposition %> 
       <%= button_to buy_path(s), remote: true, method: :put %> 
      <% end %> 
     <% end %> 
<% end %> 

games_controller.rb

def show 
    require 'enumerator' 
    @user = current_user 
    @game = Game.find(params[:id]) 
    @squares = Square.where(game_id:@game.id).all 
end 

squares_controller.rb

def buy 
    @square = Square.find(square_params) 

    respond_to do |format| 
     format.js 
     if @square.update_attributes(user_id: current_user.id) 
      format.html {redirect_to squares_path} 
     else 
      format.html {redirect_to :back} 
     end 
    end 
end 

private 

def square_params 
    params.require(:square).permit(:xvalue, :yvalue, :user_id, :game_id, :boardposition) 
end 

Game.rb

has_many :squares 
has_and_belongs_to_many :users 

validates :roomname, :roomtype, :teamone, :teamtwo, :gamedate, :squareprice, 
:maxsquares, :q1pay, :q2pay, :q3pay, :q4pay, presence: true 

accepts_nested_attributes_for :squares 

Square.rb

belongs_to :user 
belongs_to :game 

User.rb

has_and_belongs_to_many :games 
has_many :squares 

accepts_nested_attributes_for :squares 

路由

resources :games, :users, :squares 

get '/games/:id/join/' => 'games#join', as: :join 
get '/games/:id/buy/' => 'squares#buy', as: :buy 

match '/games/:id/', to: 'squares#buy', via: [:post] 

當我點擊購買廣場時出現的錯誤是「ActionController :: ParameterMissing in SquaresController＃buy」Param not found：square。

我已經嘗試了一段時間來弄清楚這一點，我相信我的路線現在是正確的，但我無法通過參數。任何幫助將不勝感激。

您還沒有傳遞的方形對象

def square_params 
**params.require(:square)**.permit(:xvalue, :yvalue, :user_id, :game_id, :boardposition) 
end 

要麼以某種方式提供方對象，通過一種形式，或刪除強參數。
