问题描述

您好我是Grails的新成员，我实施了删除操作，删除收件箱中的邮件，但是现在我想更改闪存邮件以显示2条邮件已删除而不是已删除邮件4，已删除邮件5多条消息。请帮助，下面是我的删除操作

Hi am new at Grails i have implemented a delete action that deleted messages in an inbox,, but now i want to change the flash message to display "2 Messages deleted" not "Message 4 deleted,Message 5 deleted" if deleting multiple messages. Kindly assist, below is my delete Action

def delete（）{

def delete() {

    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])
        }
    }
}

推荐答案

您可以这样做：

You could do this:

    def device = MessagingDevice.findByPhoneNumber(params.phoneNumber)

    // invoke deleteFromDevice on domain object, which returns number of objects deleted
    def count = messageInstance.deleteFromDevice(device)
    if (count) {
        flash.message = message(code: 'default.deleted.message', args: [message(code: 'message.deleted.label', default: '{0} Messages deleted'), count])
        redirect(action: "phone", params:[phoneNumber:params.phoneNumber])
    }

和您的messages.properties

and in your messages.properties

message.deleted.label={0} deleted
