    copied!<p>I'm trying to make a rails app that tests some ports of a hostname I provide. This is what I have so far:</p> <p>routes.rb:</p> <pre><code>Diagnostics::Application.routes.draw do match 'port_testing/test', :controller =&gt; :port_testing, :action=&gt; :test end </code></pre> <p>index.html.haml:</p> <pre><code>= stylesheet_link_tag 'user' .spacey %h1 Port Testing = form_tag('port_testing/test', method: 'get') do = text_field_tag :hostname, 'localhost', size: 50 - @models.each do |key,value| %input{:type=&gt;"checkbox", :name=&gt;"#{key}", :value=&gt;1, :checked=&gt;value} =key %input{:type =&gt; :submit, :value =&gt; "Test"} </code></pre> <p>port_testing_controller.rb:</p> <pre><code>require 'socket' class PortTestingController &lt; ApplicationController def index @models = {"80" =&gt; false, "443" =&gt; false, "2195" =&gt; true, "28009" =&gt; false} end def test puts "\n" hostname = params["hostname"] puts hostname ports = ["80", "443", "2195", "28009"] ports.each do |key| #puts key if params.has_key?(key) port = key.to_i is_port_open?(hostname, port) end end redirect_to("#/port_testing") end def is_port_open?(ip, port) begin Timeout::timeout(1) do begin s = TCPSocket.new(ip, port) puts "Successful" s.close return true rescue Errno::ECONNREFUSED, Errno::EHOSTUNREACH puts "Error" return false end end rescue Timeout::Error puts "Timeout" end return false end end </code></pre> <p>Right now, what I have works. I can put in a hostname in the text field, check which ports I want tested, and I get the results printed to the screen. </p> <p>However, what I would like to do is to be able to save the most recent parameters I entered. Right now, after I click test, the page reloads so it resets to the default hostname and the default port. I would like it to keep the same hostname and port as I had before. How would I do this?</p> <p>Also, I would like to have the results be put in a table and displayed on the same webpage. How would I go about doing this?</p>
