Search inside subdocument array in mongoose and treat it as if it was a normal collection (a model)

[samislam]

I have the following Schema:

const parentSchema = new mongoose.Schema({
   children: [childSchema]
})

where childSchema is:

const childSchema = new mongoose.Schema({
   name: String
})

---

I know that I can search by id as follows (when I already have the parent document):

parentDoc.children.id()

---

Now, I want to find by the name somehow as follows:

parentDoc.children.find({ name: 'Kinder' }) // not a real code, just to demonstrate what I want

• You might say, okay it's simple, just call the native JavaScript methods on arrays such as .map, since you're working with an array. That's correct, but I need to run the pre-find middleware I attached to the child schema.

---

Now, that was the first question, now, :

How about these methods?

parentDoc.children.create()
parentDoc.children.findOne()
parentDoc.children.findById()
parentDoc.children.updateOne()
parentDoc.children.findByIdAndUpdate()
parentDoc.children.deleteOne()
parentDoc.children.findByIdAndDelete()
parentDoc.children.removeOne()
parentDoc.children.findByIdAndremove()
parentDoc.children.replaceOne()
parentDoc.children.findByIdAndReplace()

Can we work with subdocument arrays just as collections? simply as if they were actually models, we can call all the above methods on them.

I'm sure there's a way to perform all the above, can anyone document this missing part of mongoose?
