Module: NuecaRailsInterfaces::V3::FormInterface::InstanceMethods

Defined in:
lib/nueca_rails_interfaces/v3/form_interface.rb

Overview

Prepended so these methods precede ActiveModel::Model’s versions in the method resolution order. When ‘base.include(ActiveModel::Model)` is called inside the `included` hook, ActiveModel ends up earlier in the ancestor chain, which would otherwise cause ActiveModel::API#initialize to intercept `new` before our param-splitting logic runs.
