【问题描述】:
在带有 Mongoose 的节点中,我想在集合 Content 中找到一个对象。它有一个名为users 的子文档列表,它具有stream、user 和added 属性。我这样做是为了在users.user 字段中获取具有某个用户的_id 属性的所有文档。
Content.find( { 'users.user': user._id } ).sort( { 'users.added': -1 } )
这似乎有效(尽管我不确定.sort 是否真的在这里有效。但是,我想匹配 两个 字段,如下所示:
Content.find( { 'users.user': user._id, 'users.stream': stream } } ).sort( { 'users.added': -1 } )
这似乎不起作用。这样做的正确方法是什么?
这是一个示例文档
