Module: Workflow::Adapters::ActiveRecordValidations::RevalidateOnlyAfterAttributesChange

Defined in:
lib/workflow/adapters/active_record_validations.rb

Overview

Override for ActiveRecord::Validations#valid? Since we are validating inside of a transition, We need to be able to maintain the errors list for the object through future valid? calls or the list will be cleared next time valid? is called.

Once any attributes have changed on the object, the following call to #valid? will cause revalidation.

Note that a change on an association will not trigger a reset, meaning that one should call errors.clear before #valid? will trigger validations to run anew.
