DS.Model#errors

When the record is in the invalid state this object will contain any errors returned by the adapter. When present the errors hash contains keys corresponding to the invalid property names and values which are arrays of Javascript objects with two keys:

• message A string containing the error message from the backend
• attribute The name of the property associated with this error message

record.get('errors.length'); // 0
record.set('foo', 'invalid value');
record.save().catch(function() {
  record.get('errors').get('foo');
  // [{message: 'foo should be a number.', attribute: 'foo'}]
});

The errors property us useful for displaying error messages to the user.

<label>Username: {{input value=username}} </label>
{{#each model.errors.username as |error|}}
  <div class="error">
    {{error.message}}
  </div>
{{/each}}
<label>Email: {{input value=email}} </label>
{{#each model.errors.email as |error|}}
  <div class="error">
    {{error.message}}
  </div>
