Loopback: Bug: nestRemoting bad applied over a referencesMany Model

[sebastianfelipe]

Description/Steps to reproduce

Supose that model A is a model which contains a relation referencesMany with model B. Then if a model C extends the model A functionalities (endpoints) using nestRemoting, we have a problem.

The error is "Error: Invalid remote method: __exists__relatedModelBName"

Thanks.

I am running into the same problem here. My setup is similar to @sebastianfelipe 's, after I had to change a relation type from "embedsMany" to "referencesMany":

PersistedModelA embedsOne ModelB
ModelB referencesMany PersistedModelC
PersistedModelA.nestRemoting("ModelB")

Also getting the error
"Cannot load the LoopBack application: Invalid remote method: __exists__PersistedModelC"

Removing nestRemoting for PersistedModelA removes the error - but also the sweet advantages of nested queries.

I submitted a PR here https://github.com/strongloop/loopback-datasource-juggler/pull/1614
But had some bugs compiling and didn't have much time to look at it again :/

Try doing this. At least, this was my patch.

 // Added because referencesMany bug
  ModelA.prototype.__exists__modelBs = function(fk, options, cb) {
    let self = this
    let types = self['modelBIds']
    if (types.indexOf(fk) > -1) cb()
    else {
      let error = new Error()
      error.statusCode = 404
      cb(error)
    }
    return cb.promise
  }

And done. The inheritance is solved. But wait... that's another bug haha, but for now it solves that problem.

The new bug is found in this thread -> https://github.com/strongloop/loopback/issues/4002

Good luck!
