为什么yaml文件上传不起作用？我认为权限问题

我想加载在配置目录中，由用户选择一个yaml文件。我有一个观点：为什么yaml文件上传不起作用？我认为权限问题

<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 %>

，我有一个控制器：

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

当用户选择文件并点击“上传”什么也没有发生，文件是不是在config文件夹。我能做什么？也许我应该使用“import yaml”并以某种方式加载它，怎么样？

日志这样说：

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

试试这个

我试过了，但是没有什么变化...... –

是否config文件夹中有正确的permisssions –

我有Windows 7和我做：config/properties/attributes /我删除了只读的检查，我确定了。但如果我追溯它的方式，它仍然是只读的。我必须这样做？为什么它不会改变？ –
