Saving a file after passing a parameter

Question

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

@bigtable - a table with rows 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 my code does not work: / I want to save @bigtable lines to a file. Each row entry in a table represents a new row in a file. And I want to save the file without redirecting the current page anywhere, but I don’t completely know why :( Please help.

Okay, I know why this does not work - I will add a new route to initialize the savefile method, but how to do it without redirecting / updating the current page with the results? Help plz

I found a solution - do not write a double post here - link to the topic with the answer: saving the variable to a file and loading it

Use <%= form_tag(url, :remote => true) do %> to make a call using Ajax, so your page will not be redirected. Use your server’s logs to see if the request is being executed (if you want to get the result of ajax call on your page, see http://www.alfajango.com/blog/rails-3-remote-links-and-forms/ ).
