传递参数后保存文件 [英] saving file after passing parameter

问题描述

以下是父级问题：将字符串保存到文件
我想传递的参数将被保存在文件（.csv）单击按钮后。

@bigtable是每行中有字符串的表。
这里是我的show.html.erb中的代码：

$ p $ ...一些代码在这里...
<％= form_tag do％>
<％text_field_tag，id =bigtable，value = @ bigtable.to_s％>
<％= submit_tag'Zapisz'％>
<％end％>


和我的控制器方法：

<$ p $
$ def






$ b $ File.open（path / to /文件，w）{| file | file.write @ bigtable.join（\\\
）}
end

我的代码不起作用：/
我想保存@bigtable字符串到文件。该表的每一行记录都是该文件的新行。而我想保存文件，而不重定向当前页面的任何地方，但完全不知道为什么:(请帮助。

好的，我知道为什么它不工作 - 我要添加一些新的路线来初始化 savefile 方法 - 但是如何不重定向/刷新当前页面的结果？plz help 解决方案

Here is the parent question: save string to file I want to pass the parameter which will be saved in file(.csv) after clicking button.

@bigtable is a table with strings in each row. Here is the code in my show.html.erb:

...some code here...
<%= form_tag do %>
  <% text_field_tag, id = "bigtable", value = @bigtable.to_s %>
  <%= submit_tag 'Zapisz' %>
<% end %>

and my controller method:

 def savefile
    @bigtable = param[:bigtable]
    @bigtable.join("\n")
    File.open("path/to/file", "w") { |file| file.write @bigtable.join("\n") }
  end

But mine code doesn't work :/ I want to save @bigtable strings to file. Each row record of the table is a new line of the file. And I want to save file without redirecting current page anywhere but completely don't know why:( Please help.

okay, I know why it doesn't work - I shoud add some new route to initialize savefile method - but how do it without redirecting/refreshing current page with results? plz help
