[Ruby] Active Record and Array error

[Neil Moomey]

Hi everyone.  I'm stumped on this seemly simple task.  Below is my Model and
the error message.  If Owner3 exists (from the db table anchorage_prop)
everything works fine but if Owner3 is null I get this error.  There is
something special about the last member of this array.  If I add something
else to the end of the array it works fine again.  It's almost as if my
@anchorage_prop.owners.each do |q| wants to loop one more time than it
should.  Any ideas?  Thanks. - Neil

# Model AnchorageProp
class AnchorageProp < ActiveRecord::Base
set_table_name "anchorage_prop"


  def owners
    owner_array=[]
    owner_array << "Owner1="+self.Owner1 unless self.Owner1.nil? ||
self.Owner1.strip == ""
    owner_array << "Owner2="+self.Owner2 unless self.Owner2.nil? ||
self.Owner2.strip == ""
    owner_array << "Owner3="+self.Owner3 unless self.Owner3.nil? ||
self.Owner3.strip == ""
  end
