Grails 编辑 Flash 删除消息

你好，我是 Grails 的新人，我已经实现了一个删除操作，删除了收件箱中的邮件，但现在我想更改闪现消息，以在删除多条邮件时显示“2 条邮件已删除”而不是“邮件 4 已删除，邮件 5 已删除”。请协助，以下是我的删除操作

def 删除() {

    def messageInstance = Message.get(params.id)

    // render error if no message found
    if (!messageInstance) {
        flash.message = message(code: 'default.not.found.message', args: [message(code: 'message.label', default: 'Message'), params.id])
        redirect(action: "phone")
    } else {
        // get the device that we are deleting from
        //specify phoneNumber so as to delete the device by phoneNumber
        def device = MessagingDevice.findByPhoneNumber(params.phoneNumber)

        // invoke deleteFromDevice on domain object, which returns true if successful
        if (messageInstance.deleteFromDevice(device)) {
            flash.message = message(code: 'default.deleted.message', args: [message(code: 'message.label', default: 'Message'), params.id])
            redirect(action: "phone", params:[phoneNumber:params.phoneNumber])
        }
    }
}

in code:

int count = 5 //number of deleted messages

flash.message = message(code: 'default.deleted.messages', args: [message(code: 'messages.label', default: 'Messages'), count])

在 messages.properties 中：

messages.label=Messages
default.deleted.messages={1} {0} deleted
