为什么yaml文件上传不起作用？ 我认为许可问题
我想加载config目录，用户选择的yaml文件。 我有一个观点：
File Upload
Upload your Yaml Configuration File
{ :multipart => true } do |f| %> 'Uploading...' %> 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
当用户选择文件并按“上传”时，没有任何反应，文件不在配置文件夹中。 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？
