title: Showing Link in Text Field in Rails
body: <p>In my Rails 3.1 app, I have a text field for comments and I want to be able to allow people to include clickable links (instead of just the url showing as plain text), as well as having the text field recognize when a user had line breaks in their text field (without the user adding html).  How can I do this?</p>
  
  <p>This works for showing a link if a user puts the html for a href:
  <code>&lt;%= simple_format(@user.description) %&gt;</code></p>
  
  <p>And this works for recognizing and displaying the line breaks from carriage returns in the text_field:
  <code>&lt;%= h(@user.description).gsub(/\n/, '&lt;br/&gt;').html_safe %&gt;</code></p>
  
  <p>However, I haven't figured out how to do both, together.</p>
