There is an Audit Type class

Each Audit Type has many Audit Items, they are accessible with the  
method:

AuditType.audit\_items

It is possible to expire audit items, this sets the expired column to 1.  
They still need to be linked with the Audit Type though, so i can not  
delete the foreign key.

When i call AuditType.audit\_items i dont want the items that have been  
expired to show, but i do not know how to do this. Any ideas on the  
best way to do it??

Thanks,  
Chris

Some how this conjures up a scene from a John Wayne movie for me.

You don’t need to use grep to see whether an array contains an element.  
You  
can use include?:

if (states.include?(‘closed’) || states.include?(‘feedback’)) &&  
(states.include?(‘open’) || states.include?(‘analyzed’))

Another aopproach is to use the Array & operator, which gives the  
intersection  
between two arrays. You can do something like this:

first\_group = [‘open’, ‘analyzed’]  
second\_group = [‘closed’, ‘feedback’]

if !(states & second\_group).empty? && !(states & first\_group).empty?

The reasoning is that, if states contains either the ‘open’ or the  
‘analyzed’  
entries, then its intersection with first\_group (states & first\_group)  
won’t  
be empty. The same for the second group.

I hope this helps
