为什么yaml文件上传不起作用？我认为权限问题 [英] Why yaml file upload does not work? I think permission problems

问题描述

我想在config目录下加载一个由用户选择的yaml文件。
我有一个观点：$ b​​
$ b

 < h1>档案上载< / h1> 
< p>上传您的Yaml配置文件< / p> 
 
< p style =color：green><％= flash [：notice]％>< / p> 
 
<％= form_for：uploadFile，：html => {：multipart => true} do | f | ％GT; 
 
< label for =upload_file>选取档案：< / label> 
<％= f.file_field：upload％> 
 <％= f.submit上传，：disable_with => '正在上传...'％> 
<％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'） |文件| 
 file.write（uploaded_io.read）
 end 
 
 flash.now [：notice] =文件已成功上传
 
 end 
 end 
  

当用户选择文件并按下上传时，不在配置文件夹中。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？

这个日志说了这个：

解决方案

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

/ p>

I would like to load in the config directory, a yaml file chosen by the user. I have a view:

<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 %>

and I have a controller:

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

When the user selects the file and press "upload" nothing happens and the file is not in the config folder. What can I do? Maybe I should use "import yaml" and load it in a certain way, how?

The log said this:

解决方案

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

Try this instead
