Yes, but you should do Owner.reset_column_information first
I mean before updating the data.
Question
If I change my mind about how I store Model data, how might I add new columns and migrate existing data over?
For example, would the following be appropriate:
class AddPropertyAAndPropertyBToOwner < ActiveRecord::Migration
def change
add_column :owners, :property_a, :string
add_column :owners, :property_b, :string
# Now I need to migrate the existing 40 records
# populating the new columns from an existing one
# Owner.all.each do |o|
# original = o.original_property
# o.property_a = original.match(/foo/).captures.first
# o.proptery_b = original.match(/bar/).captures.first
# o.save
# end
end
end
