title: Replacing the 'auto_link' method in Ruby on Rails 3.1
body: <p>I am using Ruby on Rails 3.0.7 and I know that in the 3.1 version there won't be the <code>auto_link</code> method anymore (see the <a href="https://github.com/rails/rails/blob/v3.1.0.rc4/actionpack/lib/action_view/helpers/text_helper.rb">actionpack/lib/action_view/helpers/text_helper.rb</a> for RoR 3.1). </p>
  
  <p><strong>Is there another way to have similar functions as the old <code>auto_link</code> method? That is, how can I replace that useful method in Ruby on Rails 3.1?</strong></p>
  
  <p><em>BTW</em>: why will the <code>auto_link</code> method will be removed?</p>
