# ember/no-empty-attrs

<!-- end auto-generated rule header -->

Be explicit with Ember data attribute types.

Ember Data handles not specifying a transform in model description. Nonetheless this could lead to ambiguity. This rule ensures that the right transform is specified for every attribute.

Note: this rule is not in the `recommended` configuration because the Ember Data team recommends not using transforms unless you actually want to transform something.

## Examples

Examples of **incorrect** code for this rule:

```js
const { Model, attr } = DS;

export default Model.extend({
  name: attr(),
  points: attr(),
  dob: attr(),
});
```

Examples of **correct** code for this rule:

```js
const { Model, attr } = DS;

export default Model.extend({
  name: attr('string'),
  points: attr('number'),
  dob: attr('date'),
});
```

In case you need a custom behavior, it's good to write your own [transform](https://api.emberjs.com/ember-data/release/classes/Transform).
