Rails應用程序活動記錄聲譽系統錯誤來電ID

Question

我剛剛完成ARRS的實施，後面R.貝茨Railscasts＃364。 我在放映視圖

這是與R完全不同的改變它適合我的應用程序，所以

用戶選票上的影片。貝茨之一，在索引視圖

而且在啓動上俳句

用戶投票，按鈕看起來不錯，他們在展會上亮相視圖。

然而當我點擊一個這個錯誤出現

名爲id的零，這將被錯誤地4 - 如果你真的想零的ID，請使用OBJECT_ID

任何想法任何人？

Movies_controller.rb

class MoviesController < ApplicationController 



    # GET /movies 
    # GET /movies.json 
    def index 
    @search = Movie.search(params[:q]) 
    @movies = Movie.all 


    end 

    # GET /movies/1 
    # GET /movies/1.json 
    def show 

     @movies = Movie.find_with_reputation(:votes, :all, order: 'votes desc') 
     @search = Movie.search(params[:q]) 
    @movie = Movie.find(params[:id]) 


    end 




    def search 
     @search = Movie.search(params[:q]) 
     @movies = @search.result 

     respond_to do |format| 
      format.html # index.html.erb

def vote

    @movie = Movie.find(params[:id]) 
    @movie.add_evaluation(:votes, value, current_user) 
    redirect_to :back, notice: "Thank you for voting!" 
end 

end 

Movie.rb

has_reputation :votes, source: :user, aggregated_by: :sum 

User.rb

has_reputation :votes, source: {reputation: :votes, of: :movies}, aggregated_by: :sum 

show.html.erb //電影

<div class="ratings"> 

    <em> 
    <%= pluralize @movie.reputation_for(:votes).to_i, "vote" %> 
    | <%= link_to "up", vote_movie_path(@movie, type: "up"), method: "post" %> 
    | <%= link_to "down", vote_movie_path(@movie, type: "down"), method: "post" %> 
    </em> 
</div> 

的routes.rb

resources :movies do 
    member { post :vote } 
    end 

Answer 1

def vote 
    value = params[:type] == "up" ? 1 : -1 
    @movie = Movie.find(params[:id]) 
    @movie.add_evaluation(:votes, value, current_user) 
    redirect_to :back, notice: "Thank you for voting!" 
end 

問題可能會在這裏：

add_evaluation(:votes, value, current_user) 

要求current_user你沒有。設計文件說，你需要包括 before_filter :authenticate_user!在conotroller使用current_user幫手。

使用寶石時要多留意文檔。

EIDT聊天來解決這個問題acts_as_votable寶石之後再使用的 https://github.com/ryanto/acts_as_votable代替Active Record Reputation System

Answer 2

這裏的問題是在你的add_evaluation線

改變它 「add_or_update_evaluation（：票，值，current_user）' 這將添加並更新評估部分。
