Module | Sequel::Plugins::NestedAttributes
In: | lib/sequel/plugins/nested_attributes.rb

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.plugin :nested_attributes
      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']
