    return {
      filter: {
        author: context.get('username')
      }
    };
  }, 'username')
});

Querying for a single record

Options as an object

import Model from 'ember-data/model';
import attr from 'ember-data/attr';

import { queryRecord } from 'ember-computed-query';

export default Model.extend({
  username: attr('string'),

  newestComment: queryRecord('comment', {
    filter: {
      author: 'foobar'
    }
  }, 'username')
});

Options as a callback

import Model from 'ember-data/model';
import attr from 'ember-data/attr';

import { queryRecord } from 'ember-computed-query';

export default Model.extend({
  username: attr('string'),

  newestComment: queryRecord('comment', (context) => {
    return {
      filter: {
        author: context.get('username')
      }
    };
  }, 'username')
});

Notes

• Because they're computed properties, they're lazily loaded.
• In the examples above, changing username will invalidate the computed query cache. This means that the computed query will run again on the next access.
