        return mark_safe(button_html)
    buttons.short_description = "操作"
    # 添加到list_display
    list_display = ['id','title','category','modified_time','views','status','over_time','buttons']

    tags = models.ManyToManyField(Tag, blank=True,verbose_name=u'标签')
    views = models.PositiveIntegerField(default=0,verbose_name=u'点击数')  # 阅读量
    status = models.SmallIntegerField(default=2,choices=status_choices,verbose_name=u'状态')  # 状态 

    def over_time(self):

            return mark_safe(text)
        else:
            return mark_safe("")
    over_time.short_description = '发表时间'
 
    class Meta:
