變音不起作用，通過導出一個CSV文件

-1

我有一個問題，出口與元音變音數據（如「ä」，「ü」...）在CSV文件。我嘗試了不同的解決方案，但沒有任何效果這裏是我的代碼：變音不起作用，通過導出一個CSV文件

控制器：

def bom_export 
    @configurations = [] 
    @bom = [] 

    params[:configurations].each do |configuration_id| 
     @configurations << Configuration::Configuration.find(configuration_id.to_i) 
    end 

    @configurations.each do |conf| 
     conf.bill_of_materials.each do |material| 
     @bom << material 
     end 
    end 

    respond_to do |format| 
     format.csv { 
     csv_string = CSV.generate do |csv| 
      csv << ["Id", "Titel", "Beschreibung", "Breite", "Höhe", "Länge"] 
      @bom.each do |bom| 
      csv << [bom.id, bom.title, bom.description, bom.width, bom.height, bom.length] 
      end 
     end 

     c = Iconv.new('ISO-8859-15','UTF-8') 
     send_data(c.iconv(csv_string), 
        :type => 'text/csv; charset=iso8859-1; header=present', 
        :filename => "test.csv") 

     } 
    end 
    end

試圖保存的CSV文件服務器崩潰（500）之後。沒有變音器一切正常。

也許那裏是另一種沒有Iconv的解決方案，因爲Iconv已被棄用（？） – levitas111

請發佈您在'log/development.log'中獲得的錯誤消息。 – phoet

UTF-8應該與德文字符集一起工作得很好。爲什麼你甚至會轉換它？ – phoet

你的問題是源文件中的錯誤，你永遠不會聲明爲除了US-ASCII之外的任何東西。此評論添加到您的源文件的頂部：

#encoding: UTF-8

注：請不要使用語言Iconv，它的棄用，編碼支持已被添加到Ruby 1.9。相反，使用Ruby 1.9的內置編碼方法。例如：

send_data(csv_string.encode("ISO-8859-1"), 
       :type => 'text/csv; charset=iso8859-1; header=present', 
       :filename => "test.csv")

是他的問題的正確答案？（服務器崩潰） – phoet

感謝您的建議@Linuxios，但問題仍然是一樣的:(任何其他想法爲什麼變音符號「ü」，「ä」...不工作？ – levitas111

@ user1542555，phoet：請參閱編輯。 – Linuxios

我找到了解決方案！

問題不在於導出，而在於腳本本身的編碼。

在我的控制腳本的開頭添加以下行解決了這個問題：

#!/bin/env ruby 
# encoding: utf-8

第一行是一個shebang，只對可執行腳本是必需的，所以它不會被添加到控制器文件中 – phoet

謝謝@phoet！你當然是對的！ – levitas111

對我來說這並獲得成功

send_data(csv_string.encode("UTF-8"), 
      :type => 'text/csv; charset=UTF-8; header=present', 
      :filename => "test.csv")

而

# encoding: utf-8

沒」 t幫助
