#read_attribute_for_validation(attr) ⇒ Object

ActiveModel::Error#generate_message always calls read_attribute_for_validation to supply a :value interpolation, even when a custom :message is present. Compound nested attribute names (e.g. :“line_items.name”) are not real methods on the form — return nil for any attribute scoped under a registered nested association to avoid a NoMethodError.
