文件上傳不成功，爲什麼？

我瘋了上傳一個文件到我的紅寶石3.2.8應用程序。我需要你的幫助！我想這樣的代碼：文件上傳不成功，爲什麼？

Why yaml file upload does not work? I think permission problems

，但它不工作，在「公」不創建的文件，但只有創建的臨時文件。今天，我發現了一個新的思路：

Rails 3 - upload files to public directory

所以，陽臺：

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

<%= form_for :uploadFile, :url => "/upload/uploadfile", :html => { :multipart => true } do |f| %> 
    <label for="uploadFile">Select File:</label> 
    <%= f.file_field :upload %> 
    <%= f.submit "Upload", :disable_with => 'Uploading...' %> 
<% end %>

控制器：

class UploadController < ApplicationController 
    def uploadFile 
    require 'fileutils' 
    tmp = params[:uploadFile][:upload].tempfile 
    file = File.join("public", params[:uploadFile][:upload].original_filename) 
    FileUtils.cp tmp.path, file 
    flash.now[:notice]="File has been uploaded successfully" 
    end 
end

，但同樣的問題。在「公衆」沒有文件:(

啊，上傳文件是YAML，改變什麼

我的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '3.2.8' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

gem 'sqlite3' 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 

    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

gem "comma", "~> 3.0.3" 
gem 'fastercsv', '1.5.4'

也許添加：url到form_for like

form_for :uploadFile, :url => "/upload/uploadfile"

會有幫助嗎？隨着鐵軌3.2.8你的上傳工作正常，除了我添加：url參數。

我也有導軌3.2.8，我已經添加了你的提示，但是......沒有。可能不是由於代碼而是其他問題？許可證或其他..你在你的應用程序中設置了一些東西？ –

不，全新的應用程序。也許這個問題是由Content-Type引起的：application/octet-stream？ –

我甚至不知道該說什麼，我該如何改變它？ –
