Module: Ecoportal::API::Common::Content::DoubleModel::Attributable::Nesting::CascadedCallback

Defined in:
lib/ecoportal/api/common/content/double_model/attributable/nesting/cascaded_callback.rb

Overview

Note:

this happens at instance level (not tracked at class level)

We offer helpers to implement cascaded callbacks to nested objects i.e. #as_update or #dirty?
