Loopback update embedded documents

Question

Loopback update embedded documents

Here the models :

I want to do an update of "FirstLevel" from "Master" with the "prop" as search criteria.

{
   "name": "Master",
   "base": "PersistedModel",
   "properties": {}
   },
   "validations": [],
   "relations": {
       "firstLevels": {
           "type": "embedsMany",
           "model": "FirstLevel"
       }
   },
   "acls": [],
   "methods": []
}

{
   "name": "FirstLevel",
   "base": "PersistedModel",
   "properties": {
        "prop": {
            "type": "number"
         }
   },
   "validations": [],
   "relations": {},
   "acls": [],
   "methods": []
}

With MongooseJS I can do it like this :

Master.update({'firstLevels.prop': 100},
     {
          $push: {
               'firstLevels.$.prop2': 'test'
          }
     }, { upsert: true },
          function (err) {
               ...
          }
     );

How can I do this with Loopback?

node.js
strongloop
loopbackjs

Fabien answered this question in the mailing list:

Loopback currently doesn't provide native MongoDB update commands like $push and so forth, so your best bet would be to use the connector directly - like:

var mongodb = app.dataSources.db.connector;
mongodb.collection('Master').update( ... );
