class String
Ruby on Rails 8.0.4
Since v5.2.8.1Active Model String Type
Attribute type for strings. It is registered under the :string key.
This class is a specialization of ActiveModel::Type::ImmutableString. It performs coercion in the same way, and can be configured in the same way. However, it accounts for mutable strings, so dirty tracking can properly check if a string has changed.
