如果用户在 grails 中被删除，如何在 update() 中设置当前数据

Question

删除用户时，我必须在'Date deletedDate'中设置当前数据。为此，我必须在 Update() 方法中执行此操作：如果删除了人员，请将 deletedDate 设置为当前日期。

我知道要设置我必须做的当前日期：

deletedDate = new Date(System.currentTimeMillis() - 30000))

但不确定如何在更新内部执行此操作，或者最好创建一个服务 class 来做。如果我必须创建一个新服务，我怎么知道用户何时被删除？

在此先致谢

域：

class Person{
..
String nameID
Date deletedDate
}

控制器：

 def update(Long id, Long version) {
        def personInstance = Person.get(id)
        if (!personInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'person.label', default: 'Person'), id])
            redirect(action: "list")
            return
        }
        if (version != null) {
            if (personInstance.version > version) {
                personInstance.errors.rejectValue("version", "default.optimistic.locking.failure",
                          [message(code: 'person.label', default: 'Person')] as Object[],
                          "Another user has updated this Person while you were editing")
                render(view: "edit", model: [personInstance: personInstance])
                return
            }
        }
        personInstance.properties = params
        if (!personInstance.save(flush: true)) {
            render(view: "edit", model: [personInstance: personInstance])
            return
        }
        flash.message = message(code: 'default.updated.message', args: [message(code: 'person.label', default: 'Person'), personInstance.id])
        redirect(action: "show", id: personInstance.id)
    }


    def delete(Long id) {
        def personInstance = Person.get(id)
        if (!personInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'person.label', default: 'Person'), id])
            redirect(action: "list")
            return
        }
        try {
            personInstance.delete(flush: true)
            flash.message = message(code: 'default.deleted.message', args: [message(code: 'person.label', default: 'Person'), id])
            redirect(action: "list")
        }
        catch (DataIntegrityViolationException e) {
            flash.message = message(code: 'default.not.deleted.message', args: [message(code: 'person.label', default: 'Person'), id])
            redirect(action: "show", id: id)
        }
    }

尝试以下方法（在类似情况下对我有用）：

def delete(Long id) {
    def personInstance = Person.get(id)
    if (!personInstance) {
        flash.message = message(code: 'default.not.found.message', args: [message(code: 'person.label', default: 'Person'), id])
        redirect(action: "list")
        return
    }
    try {
        // deleteDate should be saved as well
        personInstance.deletedDate = new Date(System.currentTimeMillis() - 30000))
        personInstance.delete(flush: true)
        flash.message = message(code: 'default.deleted.message', args: [message(code: 'person.label', default: 'Person'), id])
        redirect(action: "list")
    }
    catch (DataIntegrityViolationException e) {
        flash.message = message(code: 'default.not.deleted.message', args: [message(code: 'person.label', default: 'Person'), id])
        redirect(action: "show", id: id)
    }
}
