Question

我必须为桌面游戏中的p1条目执行增加值按钮“bg”但它不起作用...它保存游戏时p1 = 0但是link_to没有效果..

非常感谢任何帮助！（抱歉我的英语不好......）

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

视图

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 %>

错误消息：

:method的{{1}}选项适用于HTTP动词（link_to，:get，:post或:put）

您要执行的操作如下（使用:delete方法，更新的首选动词）

:put

并在routes.rb中：

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

Rails动态增加按钮
