act_as_votable не работает, когда я поднимаю / понижаю

Question

Я пытаюсь разрешить treatment быть голосуемым с положительными или отрицательными голосами, но методы, предоставляемые act_as_votable, не работают должным образом. Когда я пытаюсь отобразить сумму положительных и отрицательных голосов, она каждый раз возвращает 0, подразумевая, что голоса регистрируются не так, как должны.

мой treatments_controller.rb

def upvote
  @treatment = Treatment.find(params[:id])
  @treatment.upvote_by @current_user

  render 'show'
end

def downvote
  @treatment = Treatment.find(params[:id])
  @treatment.downvote_by @current_user

  redirect_to treatments_path
end

мой treatment.rb

class Treatment < ActiveRecord::Base
acts_as_votable


 has_many :review
 has_one :service


    def score
  self.get_upvotes.size - self.get_downvotes.size
end

end

мой routes.rb

resources :treatments do
  member do
    put "like", to: "treatments#upvote"
    put "dislike", to: "treatments#downvote"
  end
end

И мой treatments/show.html.erb

<div class="container">
    <div class="row">
      <div class="col-sx-12 col-sm-12 col-md-8">
        <h3><%= @treatment.name %></h3></br></br>
 <h3>
           <%= link_to "upvote", like_treatment_path(@treatment), method: :put %></br>
            <%= link_to "downvote", dislike_treatment_path(@treatment), method: :put %></br>
            <%= @treatment.score %></br> </h3>

Благодаря помощи Кристяна я понял, что вставка не происходит. Я определил current_user в методах upvote и downvote. Пересмотренные рабочие версии выглядят так.

 def upvote
  current_user = User.find_by_id(session[:user_id])
  @treatment = Treatment.find(params[:id])
  @treatment.upvote_by current_user

  render 'show'
end

def downvote
  current_user = User.find_by_id(session[:user_id])
  @treatment = Treatment.find(params[:id])
  @treatment.downvote_by current_user

  render 'show'
end
