Can Ember-Data handle two models from one JSON payload?

Question

I have JSON coming from the server which looks like:

data: {
       user: {
              address: {
                         id: "id",
                         city: "city",
                         street: "street",
                         .......
              }
              name: "name",
              ......
       }

       authentication-token: {
                         token: "token",
                         id: "id"
       }
}

The idea is to store this two models (user, authentication-token) in ember store under the same names. When I gat the above mentioned response from a server, model user is saved successfully, but model authentication-token does not get saved to the store at all. When I log the data (in the adapter) before the data is passed to serializer I see that JSON has a structure which Ember-Data expects. I don't know whether the problem is that Ember-Data cannot handle two models in success at one time, and then save it to the corresponding models, or something else. Ideas?

Now it all makes sense to me. Of course, this was the problem in your last question. Anyway, ember-data's RESTAdapter can't handle this. If you're requesting a singular resource user it expects at most this user as a singular answer. Any other resource that may be "side-loaded" has to be an array. The requested singular user can either be a record under the user key or the first entry in an array unter the users key. Everything else (except meta data) has to be plural.

In case you're requesting a plural resource users, the main response must be under the users key, any sideloaded users that aren't part of the response prfixed with _ under the _users key.

For your example all this means that your json must be formatted like this:

data: {
       user: {
              address: {
                         id: "id",
                         city: "city",
                         street: "street",
                         .......
              }
              name: "name",
              ......
       }

       authentication-tokens: [{
                         token: "token",
                         id: "id"
       }]
}

If you can't change your server, you'd have to configure the RESTAdapter to normalize the JSON data through normalize of the Serializer.
