Module: SimpleMapper::Attributes::Types::SimpleUUID

Defined in:
lib/simple_mapper/attributes/types.rb

Overview

Provides basic UUID type support derived from the simple_uuid gem.

Passes nils through unchanged, but otherwise expects to work with instances of SimpleUUID::UUID or GUID strings. Attributes using this type will store the data simply as a GUID-conforming string as implemented by SimpleUUID::UUID#to_guid. For both decoding and encoding, a GUID string or an actual SimpleUUID::UUID instance may be provided, but the result is always the corresponding GUID string.

Registered as :simple_uuid.

.encode(value) ⇒ Object

Encoded a SimpleUUID::UUID instance, or a GUID string, as a GUID string. GUID strings for value will be validated by SimpleUUID::UUID prior to passing through as the result.

Passes nils through unchanged.
