I have a word counting function that returns an object with a set of key value pairs. Something like this: {a: 4, tale: 3, of: 8, two: 3, cities: 3 }
我有一个单词计数功能,它返回一个带有一组键值对的对象。这样的事情:{a:4,故事:3,of:8,2:3,城市:3}
Obviously this object can be of varying lengths and have different key/value pairs. I'd like to add this data to an 'article' document in Mongodb. Using mongoose.js this is the best schema I can come up with. I'm concerned that mongo is creating a ton of "Word" documents with one key/value pair and an id. Is there a better way?
显然,该对象可以具有不同的长度并且具有不同的键/值对。我想将此数据添加到Mongodb中的“文章”文档中。使用mongoose.js这是我能想到的最好的架构。我担心mongo会创建大量的“Word”文档,其中包含一个键/值对和一个id。有没有更好的办法?
in /models/article.js
在/models/article.js中
mongoose.Schema({
wordcounts: [wordSchema]
})
in /models/word.js
在/models/word.js中
mongoose.Schema({
word: String,
count: Number
})
So the it would end up looking like:
所以它最终看起来像:
[{
_id: 3980923urjf0e232902343252,
wordcounts: [
{_id: 2039840297502938402934, word: "Apple", count:3},
{_id: 20398sdfsdfsdfaaa4asd3, word: "Banana", count:5}
]
}]
Is there a better way?
有没有更好的办法?

If you don't need indexing, you can use Schema.Types.Mixed
(see: http://mongoosejs.com/docs/schematypes.html )
如果您不需要索引,可以使用Schema.Types.Mixed(请参阅:http://mongoosejs.com/docs/schematypes.html)
Otherwise, you don't have to define a sub-collection, as you could just define it as:
否则,您不必定义子集合,因为您可以将其定义为:
mongoose.Schema({
wordcounts: [{
word: String,
count: Number
}]
})
