note, notebook都可设为blog
关键是, 怎么得到blog列表? 还要分页
??? 不用新建, 直接使用notes表, 添加IsBlog字段. 新建表 blogs {NoteId, UserId, CreatedTime, IsTop(置顶)}, NoteId, UserId 为unique!!
// 设置一个note为blog
添加到blogs中
// 设置/取消notebook为blog
创建一个note时, 如果其notebookId已设为blog, 那么添加该note到blog中.
设置一个notebook为blog时, 将其下所有的note添加到blogs里 -> 更新其IsBlog为true
取消一个notebook不为blog时, 删除其下的所有note -> 更新其IsBlog为false
