Question

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
