title: Adding and Updating records with EmberData
body: <p>I may be being daft but the Ember.js's Model section seems to really only cover GETing data from a REST server but not adding a new one or updating an existing one. I did notice the following:</p>
  
  <ul>
  <li><a href="http://emberjs.com/guides/models/pushing-records-into-the-store/" rel="nofollow">Pushing Records into a Store</a> -brings up <code>store.push()</code> but the coverage is brief and the use case is not practical for most web applications. </li>
  <li><a href="https://github.com/emberjs/data/blob/master/TRANSITION.md#transaction-is-gone-save-individual-records" rel="nofollow">TRANSITION.md</a> - this vital reference for folks getting into the ember-data 1.0 beta has a section which discusses the removal of transactions and thereby covers this topic inadvertently</li>
  </ul>
  
  <p>Can anyone suggest some other examples of adding or updating data using Ember Data's 1.0-beta codebase?</p>
