Access a human name from the fields of an ActiveRecord-based model in several combinations:
-
first_name_middle_name
-
first_name_middle_initial
-
fullname: first_name_middle_name_last_name
-
first_name_middle_initial_last_name
-
first_name_last_name
-
list_name: last_name, first_name
Note that the model doesn’t need attributes called first_name, middle_name, and last_name to call the gem’s methods; the methods are protected by testing with respond_to?(name_field).
However all of these fields which are present must be strings.
class User < ActiveRecord::Base
include PersonName
end
u=User.first
=> {first_name => 'Zora', middle_name => 'Neale', last_name => 'Hurston'}
u.full_name => "Zora Neale Hurston"
u.list_name => "Hurston, Zora Neale"
u.first_name_middle_name => "Zora Neale"
u.first_name_middle_initial_last_name => "Zora N Hurston"
Use memoize to make these very fast in Rails:
class User < ActiveRecord::Base include PersonName memoize :full_name memoize :list_name end
