Sql 在RubyonRails中查询关系并通过Ajax更新结果

我有一个ROR应用程序，它有许多玩家和许多推荐的游戏。游戏显示在一个提要上，玩家可以决定从这个提要中隐藏它们。隐藏函数的工作原理如下：

在player.rb中：

  has_many :hides, :foreign_key=> "hider_id",
                   :dependent => :destroy

  has_many :hidees, :through => :hides

  def hidden?(hidee)
    hides.find_by_hidee_id(hidee)
  end

  def hide!(hidee)
    hides.create!(:hidee_id => hidee.id)
  end

  def unhide!(hidee)
    hides.find_by_hidee_id(hidee).destroy
  end

隐藏控制器.rb

class HidesController < ApplicationController

  def create
    @game = Game.find(params[:hide][:hidee_id])
    current_profile.hide!(@game)
    redirect_to :back
  end

  def destroy
    @game = Hide.find(params[:id]).hidee
    current_profile.unhide!(@game)
    redirect_to :back
  end
end

routes.rb

  resources :games do
    member do
      post :publish
      post :unpublish
      get  :view
      get  :hidees, :hiders
    end

我试着做两件事：1。写一个函数，如果游戏和玩家之间的隐藏关系存在，我可以从提要中隐藏游戏，以及2。写一个“显示隐藏”按钮，允许我返回玩家“隐藏”的所有项目

到目前为止，第1部分。我在视图中有以下代码，虽然这在设置关系方面起到了作用，但它不会从提要中“隐藏”游戏——我猜我需要ajax来实现这一点

  - if current_profile.hidden?(game)
    = form_for current_profile.hides.find_by_hidee_id(game), :html => { :method => :delete } do |f|
    = f.submit "Unhide", :title => "Unhide this game."
  - else
    = form_for current_profile.hides.build(:hidee_id => game.id) do |f|
      = f.hidden_field :hidee_id  
      = f.submit "Hide", :title => "Hide this game"

非常感谢您观看这篇文章，我知道它很长，但如果您能提供任何帮助，我将不胜感激。还有，谢谢你抽出时间

  resources :games do
    member do
      post :publish
      post :unpublish
      get  :view
      get  :hidees, :hiders
    end

  - if current_profile.hidden?(game)
    = form_for current_profile.hides.find_by_hidee_id(game), :html => { :method => :delete } do |f|
    = f.submit "Unhide", :title => "Unhide this game."
  - else
    = form_for current_profile.hides.build(:hidee_id => game.id) do |f|
      = f.hidden_field :hidee_id  
      = f.submit "Hide", :title => "Hide this game"
