 A new file will be created at app/enums/alarm_priority.rb that will look like:

 Then in my ActiveRecord model, Alarm, I've added a line that calls @classy_enum_attr@. The first argument is required, and is the name of the module defined above. The second argument is optional and specifies which Alarm attribute will be used as an enumerable. 
 
 In this case, I am using the module AlarmPriority, but the name of my attribute is priority. By default, it will use the name of module as the attribute name. If I wanted to do @alarm.alarm_priority@, I would not have included the second argument.
 
 <pre>
-  class Alarm < ActiveRecord::Base
-    classy_enum_attr :alarm_priority, :priority
+class Alarm < ActiveRecord::Base
+  classy_enum_attr :alarm_priority, :priority
 
-    delegate :email?, :to => :priority
-  end
+  delegate :email?, :to => :priority
+end
 </pre>
 
 With this setup, I can now do the following:
 
 <pre>
-  @alarm = Alarm.create(:priority => :medium)
+@alarm = Alarm.create(:priority => :medium)
 
-  @alarm.priority => AlarmPriorityMedium
+@alarm.priority => AlarmPriorityMedium
 
-  @alarm.email? => false
+@alarm.email? => false
 
-  @alarm.update_attribute(:priority, :high)
+@alarm.update_attribute(:priority, :high)
 
-  @alarm.email? => true
+@alarm.email? => true
 </pre>
