Class DS.BooleanTransform

The BooleanTransform class is used to serialize and deserialize boolean attributes on Ember Data record objects. This transform is used when boolean is passed as the type parameter to the DS.attr function.

import Model, { attr } from '@ember-data/model';

export default Model.extend({
  isAdmin: attr('boolean'),
  name: attr('string'),
  email: attr('string')
});

By default, the boolean transform only allows for values of true or false. You can opt into allowing null values for boolean attributes via attr('boolean', { allowNull: true })
