Is this the multiple-models-one-form problem? If so, see this & the prior 2 railscasts:
http://railscasts.com/episodes/75-complex-forms-part-3 The problem that's not treated in those (IIRC) is how to give informative error messages when child item validation fails. IIRC, you get *something* but it's not super informative...

Here is a simple example: class Blog < ActiveRecord::Base has_many :posts validates_presence_of :name end class Post < ActiveRecord::Base belongs_to :blog validates_presence_of :name validates_presence_of :blog_id end Now, if I want to create a blog and post at the same time I don't want either to be created if one of them fails. So imagine that I have a new valid blog, but a post with no name. I do not want the blog to be created because the post failed validation.
