Class: View::DefinitionList

Inherits:
Formatter show all
Defined in:
lib/view/formatters/definition_list.rb

Overview

Creates a simple definition list for an object. This works well with ActiveRecord objects. Without a block it will render all fields. You can specify the fields using the `fields` option.

You can use a block, to further format the way the definition items are formatted.

Examples:

Without a block


= view @post, :as => :definition_list, :fields => [ :title, :author ]

With a block


= view @post, :as => :definition_list do |dl|
  = dl.view :title
  = dl.view :author
  = dl.view :published_at, :as => :date
