acts_as_votable不工作時，我upvote/downvote

我想允許treatment與upvotes或downvotes投票，但由act_as_votable提供的方法似乎沒有按預期工作。當我嘗試顯示upvotes-downvotes的總和時，它每次返回0，暗示投票不會像他們應該註冊的那樣。acts_as_votable不工作時，我upvote/downvote

我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

我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

我routes.rb

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

而且我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>

當你點擊up/downvote時看看你的服務器日誌 - 看到有什麼不對嗎？什麼是HTTP響應？之後在DB中有沒有投票？ –

@Kristján我將服務器日誌添加到原來的帖子 –

您的日誌顯示新的投票沒有INSERT。是'@ current_user.nil？'應該是'current_user'嗎？ –

由於克里斯蒂安的幫助下，我意識到沒有插入發生。我在upvote和downvote方法中定義了current_user。修訂的工作版本看起來像這樣。

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
