在猫鼬中指定架构 [英] Specify schema in mongoose
问题描述
我想知道定义此架构的最佳方法是什么
I was wondering what the best way to define this schema is:
Newsitem只能具有1个用户ID和1个任务ID. 一个任务可以属于许多新站点. 一个用户可以属于许多新站点
Newsitem can only have 1 userID and 1 task ID. A Task can belong to many newsitems. A user can belong to many newsitems
我已经搜索了示例,但我想说它们不是很多示例.我该如何用猫鼬做这件事? mongodb?我想说Newsitem的用户和Newsitem的任务都是一对多的关系.
I've searched for examples, but I'd say they are not a lot of examples. How can I do this with mongoose & mongodb ? I'd say that both User to newsitem and Task to Newsitem are one to many relations.
推荐答案
在Mongodb中,您可以引用架构中的一个集合,这样当您在newsitem中找到()文档时,猫鼬会在用户和任务中执行一次find(),因此,返回newsitem文档的过程,它将连同用户和任务一起返回newsitem.
In Mongodb you can reference a collection within a schema so when you find() a document in newsitem mongoose does a find() in user and task, so instead of returning the newsitem document it returns the newsitem with the user and the task.
