This means that you either don't load any data or that the data you are looking for couldn't be found. For example:<pre lang="ruby">@page.permalink # nil error, @page is not initialized@page.find_by_permalink('i-dont-exist') @page.permalink # nil error, there is not page found.</pre>Hope this helps. If you're really new to RoR, consider buying a few books first before diving in head-first. It really helps.As an added bonus, you could check for the nil-ness of your variable:<pre lang="ruby">@page.find_by_permalink('i-dont-exist') if @page.nil? p "Page not found!" else @page.permalink end</pre> @Patrick: You are calling #permalink on a nil object.

As an added bonus, you could check for the nil-ness of your variable:

if @page.nil?
  p "Page not found!"
else
  @page.permalink
