Empty content from promise?

问题

I'm using ember-data, I call to my API using

this.store.findAll('environment').then(function(values){
  //1
},function(reason){
  //rejected
});

And my code does go into the //1, problem is I get this object which seems pretty invalid.

Here is what my api sends back.

{
  "data": {
    "environments": [
      {
        "id": 1,
        "localePath": "C:\\XML_DEPOT",
        "name": "Acceptation 1",
        "remotePath": "D:\\XML_DEPOT",
        "databaseServerName": "blabla",
        "databaseName": "blabla",
        "port": 60903
      },
      {
        "id": 2,
        "localePath": "bob",
        "name": "Acceptation 2",
        "remotePath": "bob",
        "databaseServerName": "blabla\\blabla",
        "databaseName": "blabla",
        "port": 60904
      }
    ]
  }
}

on the second try i gave it this and still didnt like it.

{
  "data": [
    {
      "id": 1,
      "localePath": "C:\\XML_DEPOT",
      "name": "Acceptation 1",
      "remotePath": "D:\\XML_DEPOT",
      "databaseServerName": "W050A01SQL1",
      "databaseName": "MAMROT01P1_MSCRM",
      "port": 60903,
      "type": "environments"
    },
    {
      "id": 2,
      "localePath": "bob",
      "name": "Acceptation 2",
      "remotePath": "bob",
      "databaseServerName": "W050A01SQL1\\W050A01SQL1B02",
      "databaseName": "MAMROT01P1_MSCRM",
      "port": 60904,
      "type": "environments"
    }
  ]
}

this is my model declaration

//environment.js
export default Model.extend({
  id: DS.attr('number'),
  localePath: DS.attr('string'),
  name: DS.attr('string'),
  remotePath: DS.attr('string'),
  databaseServerName: DS.attr('string'),
  databaseName: DS.attr('string'),
  port: DS.attr('number')
});

Thank you !

Depending on what version of Ember you are using, and assuming your environments model is set up well (maybe you could list that just so we can rule that out), you would want the server to send you back data in one of two formats to make Ember Data happy:

Ember 1.13 (or earlier version) with its default DS.RESTAdapter (docs)

{
  "environments": [
    {
      "id": 1,
      "localePath": "C:\\XML_DEPOT",
      "name": "Acceptation 1",
      "remotePath": "D:\\XML_DEPOT",
      "databaseServerName": "blabla",
      "databaseName": "blabla",
      "port": 60903
    },
    {
      "id": 2,
      "localePath": "bob",
      "name": "Acceptation 2",
      "remotePath": "bob",
      "databaseServerName": "blabla\\blabla",
      "databaseName": "blabla",
      "port": 60904
    }
  ]
}

Ember 2.0+ with its default DS.JSONAPIAdapter (docs)

{
  "data": [
    {
      "type": "environments",
      "id": 1,
      "attributes": {
        "localePath": "C:\\XML_DEPOT",
        "name": "Acceptation 1",
        "remotePath": "D:\\XML_DEPOT",
        "databaseServerName": "blabla",
        "databaseName": "blabla",
        "port": 60903
      }
    },
    {
      "type": "environments",
      "id": 2,
      "attributes": {
        "localePath": "bob",
        "name": "Acceptation 2",
        "remotePath": "bob",
        "databaseServerName": "blabla\\blabla",
        "databaseName": "blabla",
        "port": 60904
      }
    }
  ]
}

And your model can drop the ID attribute, as you've discovered since it's assumed and added for you by Ember.

//environment.js
export default Model.extend({
  localePath: DS.attr('string'),
  name: DS.attr('string'),
  remotePath: DS.attr('string'),
  databaseServerName: DS.attr('string'),
  databaseName: DS.attr('string'),
  port: DS.attr('number')
});

Hope that gets you what you're after.
