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



has_and_belongs_to_many :people

accepts_nested_attributes_for :people


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.



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?
