Rails - Feb 2011 - Rails 3 save parent model and association if nested attributes validation fails for uniqueness

Hi,

Song
has_and_belongs_to_many :people
accepts_nested_attributes_for :people

Person
validates :uniqueness => true

If person record not present, nested attributes working great! in rails way.
i.e., inserting into songs, people and people_songs table correctly.

I am interested in:-
*If there is person exist, it should skip insertion into people table but
data should be inserted in songs and people_songs table (association
table). *
*
*
There are lots of approach to solve this problem. I usually comes with some
ugly way to deal with this. Can some body suggest me the proper Rails way to
handle this.

Thanks!
Butu

Hi, I am also facing the same problem. Unfortunately googling around,
I see recommendations of using the method find_or_create_by. But what
if I''m using nested attributes to save?

Any advise?
