    def was_published_recently(self):
        #return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
        now = timezone.now()
        return now - datetime.timedelta(days=1) <= self.pub_date <= now 
        
        
    def __str__(self):
        return self.question_text

mysql 赋给root用户权限 grant all privileges on
grant all on *.* to root@'%' identified by 'root' with grant option;

flush privileges;
刷新flush privileges;然后重启mysql，通过/etc/init.d/mysql restart命令
/etc/init.d/mysql restart　　-- 重启Mysql
