Deprecation Guide for recordIsLoaded

until: 3.0.0
id: recordisloaded

recordIsLoaded has been deprecated and is an alias for hasRecordForId, which should be used instead.

If you have this:

store.recordIsLoaded('post', 1); // false
store.findRecord('post', 1).then(function() {
  store.recordIsLoaded('post', 1); // true
});

You can change it to this:

store.hasRecordForId('post', 1); // false
store.findRecord('post', 1).then(function() {
  store.hasRecordForId('post', 1); // true
});

When using DS.RESTSerializer with previous versions of Ember Data, store.queryRecord provided support for normalizing payloads containing an array of primary data. This behavior has been deprecated because it is basically the same as using store.query and returning the first model.

Deprecated payload example with an array as the primary data:

// GET /users?username="GummyBear"

{
  "users": [{
    "id": "1",
    "username": "GummyBear"
  }]
}

Expected payload example with a single object as the primary data:

// GET /users?username="GummyBear"

{
  "user": {
    "id": "1",
    "username": "GummyBear",
  }
}

If you need to support an API that responds with an array as the primary data, you have a few options. The simplest option is to use store.query instead of store.queryRecord:

this.store.query('user', { username: 'GummyBear' }).then((users) => {
  return users.objectAt(0);
});

Another option is to override normalizeQueryRecordResponse in your serializer, manipulating the payload so it matches the expected format:

app/serializers/user.js
import DS from 'ember-data';

export default DS.RESTSerializer.extend({
  normalizeQueryRecordResponse(store, primaryModelClass, payload) {
    if (payload.users) {
      payload.user = payload.users[0];
      delete payload.users;
    }

    return this._super(...arguments);
  }
});

Another option is to customize the URL of the request made by store.queryRecord so that it makes a request that returns the expected payload with a single object as its primary data. This can be done by overriding urlForQueryRecord in your adapter:

app/adapters/user.js
import DS from 'ember-data';

export default DS.RESTAdapter.extend({
  urlForQueryRecord() {
    let baseURL = this.buildURL();
    return `${baseURL}/user-query`;
  }
});
