ember-changed-relationships v0.0.2

ember-changed-relationships

Provides a mixin that can be imported to your models adding a single function, changedRelationships. It works similar to changedAttributes. Use selectively.

Installation

• ember install ember-changed-relationships

Usage

Simply call changedRelationships on a model.

Given:

import ChangedRelationships from 'ember-changed-relationships';

const {
  Model,
  belongsTo,
  hasMany
} = DS;

export default Model.extend(
  ChangedRelationships, {

  user: belongsTo(), //initial state to user with id 1
  items: hasMany() //inital state to ids [1,2,3]
}

after calling:

model.set('user', newUser); //id 2
model.set('items', newItems); //ids [2,3]

You would be returned:

relationships: {
  user: [1,2],
  items: [ [1,2,3], [2,3] ]
}

After each model.save(), the canonical state will reset.
