Ho due modelli:
User
(e-mail: stringa)
Profile
(name: String)
Rails chiamata aggiornamento delegato
class User < ActiveRecord::Base
has_one :profile
delegate :name, :name=, :to => :profile
end
class Profile < ActiveRecord::Base
belongs_to :user
end
rails c
u = User.new
u.build_profile #=> init Profile
u.name = 'foo'
u.email = '[email protected]'
u.save #=> both User and Profile are saved
u.name = 'bar'
u.save #=> true, but changes in Profile were not saved!
u.email = '[email protected]'
u.save #=> true, new User email was saved, Profile - still not!
u.name #=> 'bar', but in database it's 'foo'
Perché il profilo non viene aggiornato (salvato solo per la prima volta)? Come risolvere questo?
