If I insist to use timestamp to store current time, how to do so in yaml? 回答1: You could use the 'Timestampable' functionality in doctrine, eg: actAs: Timestampable: created: name: created_time updated: disabled: true columns: created

问题 I'm attempting to build a query in Doctrine 2 that finds all Vacancy entities which are related to any of the given VacancyWorkingHours entities.
