不能在Apache/Passenger下工作的回形針

我在運行Apache和Phusion Passenger的登臺/生產機器上部署了我的rails應用程序，但無法正確加載Paperclip gem（或至少無法獲得應用程序使用它）。其他寶石似乎加載正常，當我在RAILS_ROOT/config/environments/staging.rb中設置config.cache_classes到false時，應用程序的其餘部分工作正常。如果設置爲true，我得到的瀏覽器（和Apache錯誤日誌）以下的乘客信息，並不能在所有使用該應用程序：不能在Apache/Passenger下工作的回形針

Error message: 
undefined method `validates_attachment_presence' for #<Class:0xb618e938> 

Exception class: 
NoMethodError

我周圍一派相當長的一段時間，但無法找到一個解決方案對於我遇到的這個問題。我希望我不能忽略一些明顯的東西...

更新21/8：在與sudo腳本/服務器-b 17x.7x.16x.3x -e分段工作正常運行軌應用程序相同的盒子工作正常。這可能是一個權限問題，乘客無法找到已安裝的Paperclip Gem？

希望你能給我一些指點，讓我知道如果你需要更多的信息！感謝馬克

在我的環境中的某些信息：

$ rails -v 
Rails 2.3.5

RAILS_ROOT /配置/ environment.rb中有這一套：

config.gem "paperclip", :version => "~> 2.3"

服務器上顯示'gem list'是什麼？ –

將其添加到原始帖子中。 – Mark

從堆棧跟蹤看來，錯誤來自app/models/image.rb的第5行 - 您是否也可以在此處發佈模型代碼？ –

OK，我已通過添加

require "paperclip"

到image.rb類解決了這個。

我現在正在使用此解決方法。

你輸錯了t他的驗證方法。根據Paperclip Rdoc，正確的方法名稱是validate_attachment_presence - 它是「驗證」而不是「驗證」。

同一問題：錯誤消息：未定義的方法'validate_attachment_presence'for＃ Exception class： NoMethodError – Mark

同時請記住，這段代碼在我的developmnet機器上工作正常。 – Mark

嘗試在has_attached_file塊之後移動validate_attachment_presence行 - has_attached_file包含Paperclip的實例方法，因此可能會在排序中出現問題。我知道開發和生產環境中的類加載不同，但我不確定這些差異的程度。

嗨，好建議。不幸的是它沒有工作，但它確實改變了錯誤信息：錯誤信息：未定義的方法'has_attached_file'爲＃ Exception class： NoMethodError – Mark

顯然，Paperclip gem沒有被加載 - 你的config/environments/staging.rb文件看起來像？ –

將config/environment.rb和config/environments/staging.rb添加到原始帖子。 – Mark
