爲什麼yaml文件上傳不起作用？我認爲權限問題

我想加載在配置目錄中，由用戶選擇一個yaml文件。我有一個觀點：爲什麼yaml文件上傳不起作用？我認爲權限問題

<h1>File Upload</h1> 
<p>Upload your Yaml Configuration File</p> 

<p style="color: green"><%= flash[:notice] %></p> 

<%= form_for :uploadFile, :html => { :multipart => true } do |f| %> 

    <label for="upload_file">Select File:</label> 
    <%= f.file_field :upload %> 
    <%= f.submit "Upload", :disable_with => 'Uploading...' %> 
<% end %>

，我有一個控制器：

class UploadController < ApplicationController 
def uploadFile 
    uploaded_io = params[:uploadFile][:upload] 
    File.open(Rails.root.join('public', uploaded_io.original_filename), 'w') do |file| 
     file.write(uploaded_io.read) 
    end 

    flash.now[:notice]="File has been uploaded successfully" 

end 
end

當用戶選擇文件並點擊「上傳」什麼也沒有發生，文件是不是在config文件夾。我能做什麼？也許我應該使用「import yaml」並以某種方式加載它，怎麼樣？

日誌這樣說：

File.open(Rails.root.join('config', uploaded_io.original_filename), 'wb+') do |file| 
    file.write(uploaded_io.read) 
end

試試這個

我試過了，但是沒有什麼變化...... –

是否config文件夾中有正確的permisssions –

我有Windows 7和我做：config/properties/attributes /我刪除了只讀的檢查，我確定了。但如果我追溯它的方式，它仍然是隻讀的。我必須這樣做？爲什麼它不會改變？ –
