Cannot add child to Parent's belongs_to

[morgz]

Seems a shame you can't do this:

Site.first.products << Book.first

Where

Site :has_many :products

Product :belongs_to :site

---

And

class Book < Product acts_as_citier

Throws an error:

ArgumentError: wrong number of arguments (1 for 0) from /Users/danmorgz/.rvm/gems/ruby-1.9.2-p0@rails3/gems/citier-0.1.12/lib/citier/child_instance_methods.rb:3:in save' from /Users/danmorgz/.rvm/gems/ruby-1.9.2-p0@rails3/gems/activerecord-3.0.9/lib/active_record/associations/has_many_association.rb:66:ininsert_record' from /Users/danmorgz/.rvm/gems/ruby-1.9.2-p0@rails3/gems/activerecord-3.0.9/lib/active_record/associations/association_collection.rb:136:in block (3 levels) in <<' from /Users/danmorgz/.rvm/gems/ruby-1.9.2-p0@rails3/gems/activerecord-3.0.9/lib/active_record/associations/association_collection.rb:480:inadd_record_to_target_with_callbacks'
