title: Rails - How to include the mail_to helper inside of a controller
body: <p>in my controller I need to format a json object, which is why I need to include several helpers.</p>
  
  <p>So far I have the following in my controller: </p>
  
  <pre><code>  include ApplicationHelper
    include ActionView::Helpers::TextHelper
    include ActionView::Helpers::TagHelper
  </code></pre>
  
  <p>This works great for simple_format, problem is when the comment.content has a email address, rails trys to do a mailto link which breaks, showing the following error in the logs: "NoMethodError (undefined method `mail_to' for...."</p>
  
  <p>Any ideas on how to add it in? I tried adding   include ActionView::Helpers::UrlHelper but that did not work.</p>
  
  <p>Thanks</p>
