TypeError: Ember.A(...).mapBy is not a function

Getting this error after loading a payload via store.query()

TypeError: Ember.A(...).mapBy is not a function at ember$data$lib$system$record$arrays$record$array$$default.extend.loadRecords (adapter-populated-record-array.js:54)

Ember: 1.13.2
Ember-Data: 1.13.4

Hey @billpull! What does your payload look like and what serializer are you using? Would you be able to put together a JSBin demonstrating this issue? Makes it much easier to debug.

@wecc I'm getting this as well. It's a blocking issue and I can't load any routes.
Shown here is the payload, after normalizeResponse, and the error.

import Ember from "ember";
import DS from "ember-data";

export default DS.RESTSerializer.extend({
    isNewSerializerAPI: true,

    normalizeResponse: function (store, type, payload, id, requestType) {
        //console.log('normalizeResponse', arguments);

        for (var key in payload.data.links) {
            if (typeof payload.data.links[key] == "object")
                payload.data.links[key] = payload.data.links[key].related;
        }

        // Example type: Skilltapper@model:user:
        // Goal is to just get "user"
        var model = type.toString();
        var new_payload = new Object();

        Ember.assert("First part of type is not 'skilltapper@model:' in <" + model + ">", model.slice(0,18) == "skilltapper@model:");
        Ember.assert("Last char of type is not ':' in <" + model + ">", model.slice(model.length-1) == ":");

        model = model.slice(18, model.length - 1);
        new_payload[model] = payload.data;

        return this._super(store, type, new_payload, id, requestType);
    },

    normalize: function (typeClass, hash, prop) {
        console.log("normalize");
        console.log(hash);
        return this._super(typeClass, hash, prop);
    },

    normalizeHash: {
        links: function (hash) {
            console.log("Got the links hash");
            return hash;
        }
    }
});

here's the serializer I have, also, Ember @1.13.0 and Ember-Data @1.13.4 and ember-cli @0.2.7

Perhaps the issue is that records should be an array but here it is a class?

[liamcoau]

@billpull and @wecc Issue resolved by using queryRecord instead of query. It was not very clear that I should have used queryRecord instead, it just said find was deprecated and I should switch to query.

[jorgelainfiesta]

@liamcoau I was also getting this error when using query, but when I tried queryRecord I get an error saying

Uncaught Error: Assertion Failed: You tried to make a query but your adapter does not implement `queryRecord`

I am using the default RESTAdapter with no custom serializer or anything fancy. Did you have to implement queryRecord by yourself?

[liamcoau]

Yes, I implemented queryRecord on my adapter. I also implemented urlForQueryRecord.

[jorgelainfiesta]

@liamcoau thanks, I'll do that then. I thought it was a default method in RESTAdapter.

[billpull]

@liamcoau can you link me to an example of your adapter implementation

Here's the full adapter:
http://pastebin.com/1EJRygXF

Here's an example of how it's called:

var user = _this.store.queryRecord("user", {
  "id": _this.session.content.auth_id,
  "include": "skills,job_title"
});

I had to do some "munging" with the id, since I needed to pass that along but the third parameter is a snapshot (not actually sure how that's supposed to be used?)...
Anyways it produces a url such as:
http://example.com/user/2lkj3l5l2jkl25j5?access_token=dkasjf43j3224256swrte&include=skills,job_title

[liamcoau]

@billpull also I know you should avoid this.session.content.etc if you can in favour of session.get("etc")

[wecc]

queryRecord should have been implemented in RESTAdapter, sorry about that. It's tracked in #3514

We should probably assert an array in finders/_query or AdapterPopulatedRecordArray.loadRecords.

@liamcoau would you like to provide a PR adding an assert?

[liamcoau]

Sure!

[IsaiahJTurner]

Is there a solution to this?

[bmac]

@IsaiahJTurner what version of Ember Data are you using? I believe this bug was fixed in ember-data 1.13.7.

[btecu]

I'm getting this error as well when I use query but findAll doesn't trigger the error.
Ember Data 2.x.

[bmac]

@btecu do you mind sharing a stack trace for this error?

@bmac If the stack trace is not enough, I could probably create a repository with this issue.
