mongoid에서 3 분마다 feed_entries를 다운로드하는 방법

Question

두 가지 모델이 source.rb와 feed_entries.rb 있습니다. 3 분마다 feed_entries를 다운로드하는 방법. 난 '때마다'보석을 시도하고 오류 NoMethodError을받은 : 개인 방법은`

source.rb '를 선택

class Source 
    include Mongoid::Document 
    include Mongoid::Timestamps 

    field :url, type: String 
    field :title, type: String 
    field :site, type: String 

    after_save :load_feed_entries 

    has_many :feed_entries, dependent: :destroy 

    def load_feed_entries 
    last_entry = self.feed_entries.last 
    if last_entry.nil? 
     feed = Feedjira::Feed.fetch_and_parse(self.url) 
    else 
     feed = Feedjira::Feed.fetch_and_parse(self.url, 
     :if_modified_since => last_entry.published_at.to_time) 
    end 

    Source.add_entries(feed.entries, self.id) 
    end 

    def self.update_all_feeds(urls) 
    Feedjira::Feed.fetch_and_parse(urls, 
     :on_success => lambda { |url, feed| 
     rss = Source.select("sources.id").where(:url => url).first 
     Source.add_entries(feed.entries, rss.id) 
     } 
    ) 
    end 

    private 
    def self.add_entries(entries, stream_id) 
     entries.each do |entry| 
      unless FeedEntry.where(guid: entry.id).exists? 
      FeedEntry.create!(
       :name   => entry.title, 
       :summary  => entry.summary, 
       :url   => entry.url, 
       :content  => entry.content, 
       :published_at => entry.published, 
       :guid   => entry.id, 
       :source_id => stream_id, 
      ) 
      end 
     end 
    end 
end 

feed.rake

task :collect => :environment do 
    urls = Source.select("sources.url").all.map { |v| v[:url] } 
    Source.update_all_feeds(urls) 
end

source.rb

def self.update_all_feeds(urls) 
    Feedjira::Feed.fetch_and_parse(urls, 
     :on_success => lambda { |url, feed| 
     rss = Source.only(:id).where(:url => url).first 
     Source.add_entries(feed.entries, rss.id) 
     } 
    ) 
    end 

feed.rake

task :collect => :environment do 
    urls = Source.only(:url).all.map { |v| v[:url] } 
    Source.update_all_feeds(urls) 
end
