The important bit of this message is the bit about nil.  You have
tried to call a method service_options on something that is nil.

So ServiceDescription.find_by_name('region') is nil, so probably there
is no record in the service_descriptions database with that name.

I guess that you are a beginner in Rails to be confused by this error.
 I suggest you work through some tutorials on Rails in order to
understand the basic principles.  A few days doing that will save you
a lot of time in the long run.  railstutorial.org is good and is free
to use online.  Make sure that you install the version of rails that
the tutorial expects.
