Thanks Bryan for your reply. For first part of my problem, I am able to figure out the nested attributes with belongs_to.
For second part, I am looking for Rails way solution to my problem. Using nested attribute. I can able to create Movie if it does not exist. And able to associate it with song model (movie_id populated correctly) work really good by rails way. I want this behavior. *But when movie already exist. I want to associate that movie id with the new song to be created using accepts_nested_attributes_for.* * * Thanks!
