推荐答案

你不必担心创建那些收藏;如果您在不存在的集合中插入文档，MongoDB将自动创建一个集合。



但是如果由于您需要一些特殊设置而不够，请使用 db.createCollection [ ^ ]在确定它是否已经存在 [ ^ ]。

You don't have to worry about creating those collections; if you insert a document in a non-existing collection, MongoDB will automatically create a collection.

However if that's not sufficient because you need some special settings, use db.createCollection[^] to create the collection after figuring out if it already exists[^].
