Subject Re: delete key value pair?
Date Thu, 16 Jul 2009 23:37:43 GMT
Try:

Person.all.each do |p|
 p[:name] = "#{p[:first_name]} #{p[:last_name]}"
 p.delete(:first_name)
 p.delete(:last_name)
 p.save
end

If not try using a string key instead of a symbol: p.delete('first_name')

Also, make sure to remove the first_name and last_name properties in your
model.
