def getEnvironment
  fullpath = File.expand_path(__FILE__,RAILS_ROOT)
  if fullpath =~ /\/dev\// then 'development'
  elsif fullpath =~ /\/test\// then 'test'
  elsif fullpath =~ /\/prod\// then 'production'
  else 'development'
  end
end

#RAILS_ENV  = ENV['RAILS_ENV'] || 'development'
RAILS_ENV = getEnvironment
