Models for subdocuments. about mongorito HOT 17 OPEN

There's no ability to save sub-models, but you can save document with nested fields. Is that what you want?

from mongorito.

Well let's say I have a domain model. And within domain model I have an array of server documents which I want to have a model for. Very much like mongoose child schema models.

from mongorito.

No, this feature is not supported currently.

I actually just realized the mongoose does not allowed for subjdocument child schema models. They do allow subdocument arrays of models though:
eg:

Not Allowed:

parentSchema = new Schema({
attr: 'hi',
child:  childSchema  // not allowed
children: [childSchema] //allowed
})

👍 -- I was thinking of switching over from Mongoose to Mongorito but I can't without this feature.

Is this possible yet?

from mongorito.

No, not yet. If this functionality is critical for you, I recommend going with Mongoose, because I'm very short on time lately, so I can't promise any ETA.

@vdemedes I guess I can do a pull request with some of the code I have come up with.

I have one question you might be able to help with, how would you go about figuring out where the sub document class is. With Doc.get('sub').get('test') you can load the entity into the parent class because it is already imported; But do you have any idea how you might figure out what class to load the sub into?

Actually i guess it could be done with module.parent however not the best solution... It would require modules never change their directory

Something like:

May work, not sure how to make the getAttributes more efficient?

from mongorito.

Not sure I understand your question, could you clarify?

from mongorito.

If we were to allow sub-documents; wouldn't when we run a query on a parent document we need to require the sub-document class:

class parentDocument extends mongorito.Model {

}

class childDocument extends mongorito.Model {

}

let ParentDocument = new parentDocument({
    'child' : yield new childDocument({
        'title' : 'test'
    }).save();
});

In the above case, finding the parent document would return information about the child document, but I am unsure how to use this information to require and load the childDocument class. What would you use to store the location of the childDocument class in the parentDocument document?

Oh I see now. We could modify Query#populate() to convert inline data to models straight away. Right now populate() works just like in Mongoose. Given this document:

{
  "comments": [1, 2, 3]
}

where [1, 2, 3] are ObjectIDs, we can find documents with those ids and create a Comment model for each of them:

let post = await Post.populate('comments', Comment).findOne();
// post.comments now is an array of Comment models

So we could modify implementation of .populate() to avoid find operation and create a new model straight away, if current array item is not an ObjectID:

if (isObjectId(item)) {
  return model.findById(item);
} else {
  return new model(item);
}

Let me know if that's unclear ;)

from mongorito.

That works, I will put together a pull request this week.

Cool!

is this merged yet?

from mongorito.

Nope, it was never implemented. Hope to implement this in the next major version - #138.
