I assume the square brackets are not in the string, so that a real string might look like : "The administrator is logged in via michael-desktop" ? If so, you'll probably want to play with some string matching methods. http://www.ruby-doc.org/core-1.9.3/String.html "match" is a good place to start. class MyModel < AR::Base # my model has a big string field called "note_details", from # which I want to extract the username and hostname values def username note_details.match(/The (\S*) is logged in via (\S*)/)[1] end def hostname note_details.match(/The (\S*) is logged in via (\S*)/)[2] end end in the view you can access @my_model.username and @my_model.hostname like any other attributes. If you have any issue with performance, you could memoize the results, so you only run the .match once.
