title: link_to send parameters along with the url and grab them on target page
body: <p>How can i have a link on a page that takes the user to another URL and passes along a parameter and on the target url how can we pick up that parameter.</p>
  
  <p>usually I add links like following:</p>
  
  <pre><code> &lt;%= link_to "Add Product", '/pages/product' %&gt;
  </code></pre>
  
  <p>But how can I send parameters along with this url? Can I pick them in the target action by <code>using params[:parm_name]</code></p>
