title: Using HTML in Rails flash messages
body: <p>I use flash[:error] to display a simple message to users that they cannot do a delete operation under certain conditions. I also have a link that will help them to get information about the entity that they wanted to delete and why they cannot do so. </p>
  
  <p>Is it advisable to include this hyperlink in the flash message? Which would mean that I would have a HTML fragment in my controller. If not, how would I go about doing this?</p>
