Strange behavior with embedded models (embedsOne --> embedsMany)

[Fadi Chalfoun]

I am encountering a strange behavior accessing embedded models. It might be the way I am structuring things but basically I have a model with an "embedsOne" relation and that model that is embedded has an "embedsMany" relation.

I have successfully created the "embedsOne" model and added a single record to that model's "embedsMany" collection.

User:

"relations": {

    "provider": {

      "type": "embedsOne",

      "model": "Provider",

      "property": "providerAccount",

      "options": {

        "validate": true,

        "forceId": false

      }

    }

  }

Provider:

"relations": {

    "allRatings": {

      "type": "embedsMany",

      "model": "Rating",

      "property": "allUserRatings",

      "options": {

        "forceId": false,

        "validate": true

      }

    }

  }

GET 

http://localhost:3000/api/providers/1/allRatings

RESULT

[

  {

    "rating": 4,

    "comment": "This rocks!!",

    "username": "Jack",

    "userId": 1,

    "id": 1

  }

]

However, when I do a COUNT:

GET

http://localhost:3000/api/providers/1/allRatings/count

RESULT

{

  "count": 0 <--- count is zero!

}

I'm a bit confused as to why this is happening, seems like I should be getting consistent results through these different APIs based on the model.

I think you are experiencing the issue that I had posted here https://groups.google.com/d/msg/loopbackjs/YyFXDDyOCQw/K3moL3MiBAAJ

And an issue reported on GitHub: https://github.com/strongloop/loopback-datasource-juggler/issues/258

Alternate: Get all embedded items and use .length to count.

Thanks for the response, I also opened an issue which brings up that problem and a few others related to embedded models here: https://github.com/strongloop/loopback-datasource-juggler/issues/727. Seems that embedded models implementation is still fairly incomplete in Loopback unfortunately.
