I'm writing a migration to merge my first and last name fields into a single name field. However, writing to the new name column doesn't work within the migration. Why is this so?
def self.up add_column :users, :name, :string
for user in User.all user.name = user.first_name + ' ' + user.last_name user.save! # <= name is not actually saved here. end
remove_column :users, :first_name remove_column :users, :last_name end
