[["Alaska", "AK"],...].each do |name, abbreviation| Organization.update_all("state = '#{abbreviation}'", "state = '#{name}'") end You really don’t even need to load the AR objects…

[["Alaska", "AK"],…].each do |name, abbreviation|
Organization.update_all(“state = ‘#{abbreviation}’”, “state = ‘#{name}’”)
end

If you mean, in this specific case, could I have put in a callback to change the 'state' attribute at save time, sure. I seriously thought of that. But your blog post sort of inspired me to think about large collection updates. Plus, I've always been a bit anal about my data. If I see something that needs to be fixed, I want to fix it now. @Daniel: I’m not sure I follow.

Looks like it fits the problem well. I wonder if it would have been possible to change the input or to add a callback to Organization to prevent needing to do a bulk conversion after importing?
