mongoid_nested_fields

MongoidNestedFields is a gem aimed at CMS projects that need handling of complex types in one field. Nested fields can be nested into each other. Validations are performed on whole tree.

Example

class Article
  include Mongoid::Document

  field :title
  nested_field :body, :allowed_types => [ParagraphWithSubtitle, ImageWithCaption, ImageGallery]

end

class ParagraphWithSubtitle
  include MongoidNestedFields::NestedField

  field :paragraph
  field :subtitle

  validates_presence_of :paragraph
end

class ImageWithCaption
  include MongoidNestedFields::NestedField

  field :image
  field :caption

end

class ImageGallery
  include MongoidNestedFields::NestedField

  field :gallery_name
  nested_field :gallery, :allowed_types => [ImageWithCaption]

end
