How do I make my response upto the required standard

So, I have a backend rails application running which is responding for a particular request as follows

{"id": 68,"name": "name","email": "email"}

But in ember, I'm getting this error

Error: Assertion Failed: normalizeResponse must return a valid JSON API document:
* One or more of the following keys must be present: "data", "errors", "meta".
at Object.assert (index.js:163)
at normalizeResponseHelper (-private.js:7428)
at -private.js:13291
at Backburner._run (backburner.js:1010)
at Backburner._join (backburner.js:986)
at Backburner.join (backburner.js:757)
at -private.js:13287
at tryCatcher (rsvp.js:335)
at invokeCallback (rsvp.js:506)
at publish (rsvp.js:492)

I tried wrapping everything under a 'data' array, then I got this error

Error: Assertion Failed: normalizeResponse must return a valid JSON API document:
* Top level of a JSON API document must be an object
at Object.assert (index.js:163)
at normalizeResponseHelper (-private.js:7428)
at -private.js:13291

at -private.js:13287
at tryCatcher (rsvp.js:335)
at invokeCallback (rsvp.js:506)
at publish (rsvp.js:492)

How do I normalize it all and where, backend or frontend?

update: I made a hash response = {:data=>@user}, and then returned response.to_json I got this 

Error: Assertion Failed: Encountered a resource object with an undefined type (resolved resource using (unknown))

So, the only way I was able to make this work was by strictly adhering to the JSON standards.

I changed my response to be exactly like in the format specified in the ember guides

{
    "data": {
        "type": "user",
        "id": "123",
        "attributes": {
            "name": "Jeff",
            "email": "[email protected]"
        }
    }
}

Still looking for a way to override it

The default for ember-data is to use the JSON:API standard. This isn't a requirement though so you have two options:

1) You can modify the output on your server to meet that standard, there are some libraries to do this for you, but I haven't gone that route so I'm not up to date on what is current.

2) You can tell ember to parse your response differently, you do this by customizing the adapter for you application.

Our API looks a lot like yours and in my app/adapters/application.js file I have:

import DS from 'ember-data';

export default DS.RESTAdapter.extend({
});

Documented at https://guides.emberjs.com/release/models/customizing-adapters/. This is a fully supported way to customize ember to meet your needs and other tools like ember-cli-mirage also offer support for this less structured REST adapter approach.

I don't know Ember, but going from the error messages you have provided there's two constraints that have been highlighted.

  • The top level of the JSON must be an object, and
  • that object must have one of these keys present: "data", "errors", "meta"

Given that information I would try returning this:

{"data": {"id": 68,"name": "name","email": "email"} }
