Public Class Methods
Add a new type to the registry, allowing it to be referenced as a symbol by ActiveRecord::Base.attribute. If your type is only meant to be used with a specific database adapter, you can do so by passing adapter: :postgresql
. If your type has the same name as a native type for the current adapter, an exception will be raised unless you specify an :override
option. override: true
will cause your type to be used instead of the native type. override: false
will cause the native type to be used over yours if one exists.
