Deprecation Guide for HasManyReference.push Invalid Data

feature: ds-overhaul-references

In previous versions of Ember Data, HasManyReference#push supported pushing data that was almost formatted as a JSON API Relationship Object, but wasn't quite correct. Pushing data that is formatted this way has been deprecated. You should refactor your code to instead push a properly formatted JSON API Relationship Object.

For example, if you previously had something like:

let commentsData = {
  data: [
    { data: { type: 'comment', id: 1 } },
    { data: { type: 'comment', id: 2 } }
  ]
};

let post = this.store.peekRecord('post', 123);

post.hasMany('comments').push(commentsData);

You could remove this deprecation by refactoring your code to:

let commentsData = {
  data: [
    { type: 'comment', id: 1 },
    { type: 'comment', id: 2 }
  ]
};

let post = this.store.peekRecord('post', 123);

post.hasMany('comments').push(commentsData);
