Class BooleanTransform
publicThe 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
attr function.
Usage
import Model, { attr } from '@ember-data/model';
export default class UserModel extends Model {
@attr('boolean') isAdmin;
@attr('string') name;
@attr('string') email;
}
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 })
import Model, { attr } from '@ember-data/model';
export default class UserModel extends Model {
@attr('string') email;
@attr('string') username;
@attr('boolean', { allowNull: true }) wantsWeeklyEmail;
}
