ActiveSupport::InheritableOptions (original) (raw)

Inheritable Options

InheritableOptions provides a constructor to build an OrderedOptions hash inherited from another hash.

Use this if you already have some hash and you want to create a new one based on it.

h = ActiveSupport::InheritableOptions.new({ girl: 'Mary', boy: 'John' })
h.girl # => 'Mary'
h.boy  # => 'John'

If the existing hash has string keys, call Hash#symbolize_keys on it.

h = ActiveSupport::InheritableOptions.new({ 'girl' => 'Mary', 'boy' => 'John' }.symbolize_keys)
h.girl # => 'Mary'
h.boy  # => 'John'
