如何获得特定型号的 acts_as_votable 结果？

Question

我正在与 acts_as_votable gem 合作进行一个项目，该项目将允许用户 'like' 他们最喜欢的课程和他们最喜欢的指南。然后，收藏的指南将显示在一页上，而收藏的课程将显示在另一页上。我在我的控制器中检索特定于模型的结果时遇到问题，下面是有效但未限定特定控制器范围的代码。

class FavoritesController < ApplicationController
 def guides

 end

 def courses
  user = current_user
  @courses = user.find_up_voted_items
 end
end

这是我唯一可以工作的代码，我意识到目前控制器中没有任何东西可以将结果缩小到特定模型，但我无法得到我尝试工作的任何东西。

Answer 1

来自 acts_as_votable 文档：

Members of an individual model that a user has voted for can also be displayed. The result is an ActiveRecord Relation.
@user.get_voted Comment

@user.get_up_voted Comment

@user.get_down_voted Comment

所以在你的情况下我会使用：

class FavoritesController < ApplicationController
  before_action :get_user, only: %i[guides courses]

  def guides
    @guides = @user.get_up_voted Guide
  end

  def courses
    @courses = @user.get_up_voted Course
  end

  private

  def get_user
    @user = current_user
  end
end
