在ajax請求中出現部分錯誤導致出錯

我有一個部分，我試圖通過create.js.erb來加載，問題在於，當我可以從視圖中部分加載時，它會加載正常，但是當我嘗試調用它時在阿賈克斯行動我得到每個https://gist.github.com/4191176 在ajax請求中出現部分錯誤導致出錯

hashtag.rb

class Hashtag < ActiveRecord::Base 

    attr_accessible :text, :profile_image_url, :from_user, :created_at, :tweet_id, :hashtag, :from_user_name 

def self.pull_hashtag(hashtag) 
    hashtag_scrubbed = hashtag 
    Twitter.search("%#{hashtag}", :lang => "en", :count => 100, :result_type => "mixed").results.map do |tweet| 
    unless exists?(tweet_id: tweet.id) 
     create!(
      tweet_id: tweet.id, 
      text: tweet.text, 
      profile_image_url: tweet.user.profile_image_url, 
      from_user: tweet.from_user, 
     from_user_name: tweet.user.name, 
      created_at: tweet.created_at, 
     hashtag: hashtag 
     ) 
     end  
    end 
    end 
end

hashtags_controller

class HashtagsController < ApplicationController 

    def home 

    end 

    def vote 
     @random_hashtags = Hashtag.order("RANDOM()").limit(4) 
    end 

    def show 


    end 

    def index 

    end 

    def create 
     Hashtag.pull_hashtag(params[:hashtag]) 
     respond_to do |format| 
     format.html { redirect_to vote_path }

是，:object => @random_hashtags是不一樣的給予@random_hashtags值，無需手動閱讀我認爲這是說，你可以在你的部分「_vote_tveet」（在這種情況下，有從值使用變量vote_tweet@random_hashtags必須已經啓動）。所以，如果你仍然在使用@random_hashtags並且在控制器中給它一個值，那麼你應該跳過:object => @random_hashtags在create.js.erb中的行

它幫助，如果我定義@random_hashtags = Hashtag.order（「隨機（）」）。限制（4）

在創建控制器。
