从上传中获取文件路径 [英] Grab file path from upload

问题描述

我有一个 RoR 脚本，当给定 XML 文件的文件路径时，它会解析它.我希望能够使用 GUI 找到该文件，然后允许我的脚本运行.这是我在视图中的内容:

I have an RoR script that when given the file path for an XML file, will parse it. I want to be able to find the file with the GUI, and then allow for my script to run. Here's what I have in the view:

<%= form_for :setup, :html=>{:multipart=>true}, :url=>{action=>"create"} do |f| %>
<%= f.file_filed :my_file %>
<%= f.submit "Upload" %>
<% end %>

创建区域的控制器是:

$XML_FILE = params[:my_file]
routers = Router.new
@title = routers.overall_setup
if @title == "Everything worked" then
  redirect_to "/"
end

基本上从这里开始，您如何找出文件路径?我知道一旦可以将正确的文件路径放置到 $XML_FILE 中，其余代码就可以工作

Basically from here, how do you snag the file path out? I know that once the correct file path can be placed to $XML_FILE that the rest of the code works

推荐答案

提交表单后，您可以通过以下方式找到上传的文件:

After you've submited a form you can find upploaded file this way:

path = params[:setup][:my_file][:tempfile].path

其中 params[:setup][:my_file] 是您在表单中的 file_filed 名称

where params[:setup][:my_file] is your file_filed name in the form

path = params[:setup][:my_file].path
