我正在編寫一個Rails應用程序&,此刻我正在生成站點地圖生成器。一切都很好,在我的電腦上仍然很好。但是當我將它部署到Heroku時,我遇到了一個問題。Heroku在部署後只運行一次查詢

發電機的工作原理很簡單:它只是寫一個資源的所有URL和代碼如下所示:

控制器:

class SitemapController < ApplicationController 
    layout nil 

    def index 
     @solutions = Solution.find(:all, :order => "updated_at DESC") 
     @base_url = "http://#{request.host_with_port}" 
     headers['Content-Type'] = 'application/xml' 
     def index 
      respond_to do |format| 
       format.html 
       format.xml 
      end 
     end 
    end 
end 

查看:

<% if @solutions %> 
    <url> 
     <loc><%= "#{@base_url}#{solutions_path}" %></loc> 
     <lastmod><%= @solutions.first.updated_at.to_s(:sitemap) %></lastmod> 
     <priority>0.6</priority> 
    </url> 
    <% @solutions.each do |solution| %> 
    <url> 
     <loc><%= "#{@base_url}#{url_for(solution)}" %></loc> 
     <lastmod><%= solution.updated_at.to_s(:sitemap) %></lastmod> 
     <priority>0.5</priority> 
    </url> 
<% end %> 

正如我」我已經告訴過,在本地它工作得很好,但是在Heroku上,預期的結果在部署之後只顯示一次,其他時候沒有鏈接顯示,因爲沒有選擇解決方案。

下面是日誌:

因此,大家可以看到Solution Load僅在第一請求發出並在其他的跳過。 你有什麼想法是什麼問題?

順便說一句,我沒有嘗試過以前的版本,但從谷歌網站管理員工具,似乎一切都很好。這可能是由我所做的格式更改造成的嗎?我已經添加了下一行

配置/初始化/ time_formats.rb

Time::DATE_FORMATS[:sitemap] = "%Y-%m-%d" 

,並在控制器

.to_s(:sitemap) 

方法調用的updated_at

我會非常感謝任何回覆或提示。

你能提供更多的信息從控制器,什麼是before_filters存在,什麼樣的方法,等等? – andrewpthorp 2012-01-05 17:25:24

@andrewpthorp編輯描述,現在完整控制器顯示 – Uko 2012-01-05 17:36:38

你的控制器代碼是各種果味。出於某種原因,您有兩次(本身內)def index。你應該使用:

def index 
    @solutions = Solution.find(:all, :order => "updated_at DESC") 
    @base_url = "http://#{request.host_with_port}" 
    headers['Content-Type'] = 'application/xml' 
    respond_to do |format| 
     format.html 
     format.xml 
    end 
end

哇。你真棒:)這麼簡單的解決方案,非常有幫助。 Double'def index'對我來說看起來也是錯誤的,但是當我從一些教程中複製它時,我認爲它有某種紅寶石魔法 – Uko 2012-01-05 17:51:09
