Validations on nested attributes fail on nil foreign key on object creation

Reported by Daniele Orlandi | May 15th, 2010 @ 12:50 AM


class Tag
  belongs_to :post
  validates_presence_of :post

class Post
  has_many :post_tags
  accepts_nested_attribute_for :post_tags

On Post creation save fails because tag's post is not yet set to the new Post id.

In facts, if the validation is removed the save is successful and the post_id is correctly filled in.
