title: How I use post method in Ruby on Rails
body: <p>when I submit one page to another, the sites shows the information!
  Someone told me to use post to avoid it. however, when I use post method it doesn't work.</p>
  
  <pre><code>&lt;form action="\look\at", method="post"&gt;
  Select your new car's color.
  &lt;br&gt;
  &lt;input type="radio" name="radios1" value="red"&gt;red
  &lt;input type="radio" name="radios1" value="green"&gt;green
  &lt;input type="radio" name="radios1" value="blue"&gt;blue
  &lt;br&gt;
  &lt;br&gt;
  &lt;input type="submit"/&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>When I submit I can not see <code>\look\at</code> page. but I delete <code>method="post"</code> It works well.
  How I use post method?</p>
