Describing Records: to_label

When ActiveScaffold needs to present a string description of a record, it searches through a common list of record properties looking for something that responds. The search set, in order, is: :to_label
, :name
, :label
, :title
, and finally :to_s
. So if your schema already has one of those fields, it’ll be automatically used. But you can always define a to_label method to customize the string description.
Example:
class User < ActiveRecord::Base # ActiveScaffold will automatically use this name method to describe a # record of this type def name "#{first_name} #{last_name}" end end class ForumPost < ActiveRecord::Base # Assuming that every Post has a title attribute, ActiveScaffold will #automatically use that to describe a record of this type end class Car < ActiveRecord::Base # But you can always just define your own to_label method def to_label "#{self[:year]} #{self[:model]}" end end
