Rails動態增加按鈕

Question

我必須爲桌面遊戲中的p1條目做一個增加值按鈕「bg」，但它不工作...它用p1 = 0保存遊戲但link_to沒有效果。

非常感謝您的幫助！ （和我的英語不好對不起......）

控制器

def create 

@game = Game.new(params[:game]) 
@game.p1 = 0 


respond_to do |format| 
    if @game.save 
    format.html { render action: "show" } 
    end 
    end 
end 

def show 

@game = Game.find(params[:id]) 

respond_to do |format| 
    format.js {render 'hnew'} 
    end 

end 

def add_three_points 
    @game = Game.find(params[:id]) 
    @game.update_attribute(:p1, @game.p1 + 3) 
end 

意見

show.html.erb

<%= render 'hnew' %> 

hnew.js.erb

$('#ajax_hidden').html("<%= escape_javascript(render('hnew')) %>"); 

_hnew.html.erb

<%= link_to "bg", add_three_points_path(@game.id), {remote: true, method: :put}, 
    class: 'btn btn-small' %> 
<%= @game.p1 %> 

錯誤消息：

的link_to的:method選項是HTTP動詞（:get，:post，:put或:delete）

你什麼想要做的是低於（使用:put方法，更新的首選動詞S）

<%= link_to "bg", add_three_points_path(@game), {remote: true, method: :put}, class: 'btn btn-small' %> 

和routes.rb中：

put 'add_three_points' => 'games#add_three_points', :as => :add_three_points
