我有一个网站,用户可以在帖子上发表评论或回复评论。用户还可以喜欢回复或评论。但是,在回复表中还有另一个名为reply_to的字段。这是我当前的架构:
Comment
id
user (foreign key)
post (foreign key)
comment
Reply
id
user (foreign key)
reply_to (who the user is replying to)
comment (foreign key)
reply
CommentLike (Table that shows which user liked which comments)
id
comment (foreign key)
user (foreign key)
like (1 = likes, 0 = dislikes)
ReplyLike (Table that shows which user liked which replies)
id
reply (foreign key)
user (foreign key)
like (1 = likes, 0 = dislikes)
这看起来像是一个好的架构,还是有更好的方法来创建这种结构?
我建议下面的结构只有2个表:
Comment:
id
user (foreign key)
post (foreign key)
comment_text
parent_comment_id (null or -1 if a new comment and comment_id of the parent if a reply)
CommentLike (Table that shows which user liked which comments):
id
comment (foreign key)
user (foreign key)
like (1 = likes, 0 = dislikes)
reply
本身只是一个comment
,只是一个父母评论的孩子。因此,我不会把它变成一个单独的实体。
