I think the problem with doing that is that the arrays contain instances of models.
Sounds like skt wants to consider an instance unique based on only two attributes of each instance. The best way might just to loop over the arrays and append them to a 4th array if the 4th array doesn't already contain the item. Might be able to turn it into a one-liner using inject or map, but that might not be readable. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
