The nested_attributes plugin allows you to update attributes for associated objects directly through the parent object, similar to ActiveRecord‘s Nested Attributes feature.
Nested attributes are created using the nested_attributes method:
Artist.one_to_many :albums
Artist.nested_attributes :albums
a = Artist.new(:name=>'YJM',
:albums_attributes=>[{:name=>'RF'}, {:name=>'MO'}])
# No database activity yet
a.save # Saves artist and both albums
a.albums.map{|x| x.name} # ['RF', 'MO']
