论坛帖子置顶功能的设计问题

hi,all

我最近在做一个论坛的推荐功能的时候,不知道该怎么实现会比较好。

  • 需求

    • 管理员可以在后台编辑帖子,帖子可以被推送到首页的推荐位,版块本身的推荐位,还有全局的推荐位(就是每个版块的推荐位都要出现这个帖子)。
    • 被推荐的帖子有多种属性类别,比如置顶帖、精华帖等等。
  • 初步的实现方案
    我用了三张表(common_top_recommend),让管理员可以在后台进行编辑。字段如下:

<br>-- common_top_recommend表

id  -- 自增id
post_id -- 帖子id
top_recommned_position_id --发布的位置id,关联另外一张位置表,比如首页、版块、全局等
type_id --类别id,关联另外一张类型表,比如是精华、置顶、公告等
category_id --版块id 

--common_top_recommend_position表
id  -- 自增id
name -- 显示的名字
codename -- 用来匹配的名字,比如index,category,global这样 

--common_top_recommend_type表
id -- 自增id
name -- 显示的名字
codename -- 用来匹配的名字,比如top/digest/announce等
Copy after login
Copy after login

比如,查找出某一个版块的置顶帖:

select r.post_id from common_top_recommend as r left join common_top_recommend_position as p on r.top_recommned_position_id=p.id where r.category_id=1 or p.codename="global" ;
Copy after login
Copy after login

这样的话,就可以查找出当前版块的置顶贴了。

不过我觉得这样的实现可能有些问题,我参考了下discuz和phpwind的代码,好像都是通过一个display_order字段来完成位置的操作的,但具体实现细节还不是很清楚。

不知道有没更好更轻量的方案呢?
